You can try some of these methods:

i. In the humongous stack trace, search for workflow script with the line 
number, like, for example, 'workflow script: 70'.

Pls excuse for the shameful drum beating.

ii. https://dzone.com/articles/10-tips-to-debug-jenkins-pipelines

If the image was built by you, then you can provision groovy (kind of 
startup) scripts that can be baked in to the Docker image (as part of 
Docker build process). 

Docs in this repo could give you some leads,

Adding to what has been confirmed by Alok Kumar, with the plugin installed, 
you can set fixed uptime for the instances to be alive. Post that, they 
will be destroyed.

checkmarx plugin installation

[Ramanathan Muthaiah]

>From the update center, it is possible to install checkmarx plugin, the 
plugin version available is 8.90.4.

However, checkmarx releases page 
(https://github.com/jenkinsci/checkmarx-plugin/releases) shows many 
versions later than 8.90.4; however, there is no hpi files to download.

Has anything changed with the integration of checkmarx in Jenkins?

Am interested to know how you managed this config i.e. SSH connectivity 
from the master to external build agent or node.

For a while, I have been searching thru' docs, this forum and SO but could 
not find proper solution.

Would appreciate if you can pls outline the functional config or procedure.

 Maybe, you could add a check (prior to the checkout stage) for the 
incoming branch, if it's per the requirements, then move on to build other 
stages.

This sounds like some missing or incorrect config settings.

Also, if you are using declarative pipeline model in the code repo, this 
thread may be of some help to you.

Why not save the return values to a file in the build workspace and use 
that file in the subsequent stages?

Git(hub) plugin and triggering freestyle build based on comment string in PR

[Ramanathan Muthaiah]

In our enterprise setup, we have bunch of 'freestyle' jobs that use Github 
pullrequest builder plugin (GHPRB)   -- 
in the config of these jobs, it it setup to look for certain words in the 
incoming pull requests (PRs). This setup is working without any problems.

We want to consolidate the use of such external plugins. Specifically, to 
move away from GHPRB plugin and start using the suite of plugins related to 
Git, and Github.

However, it seems migrating the freestyle jobs to re-use (already installed 
and used for pipeline build jobs) the suite of Git and GitHub plugins, it 
is not possible(?) to trigger fresh builds for the incoming PR by scanning 
the comments. Is this true (that this functionality cannot be achieved with 
this combination of freestyle + git* plugins)? 

Would be interested to know if anyone has explored this and got it working?

/Ram

P.S: 

Eclipse' CI infra hosts several builds jobs for JGit. One among them is 
pipeline style build setup -- 
https://ci.eclipse.org/jgit/job/stable/job/jgit.gerrit-pipeline/. In the 
landing page, it is claimed that ". . . can also be triggered by a comment 
containing "trigger build" "

Access build duration in 'freestyle' jobs, for use in mail notifications

[Ramanathan Muthaiah]

Hi Folks,

New Year wishes to all of you.

Few weeks back, I migrated a production instance of Jenkins from v2.32 
(legacy infra inherited few years back) to v2.190. 

Post successful upgrade, some of the jobs, hosted in this instance, are 
unable to compute(?) BUILD_DURATION -- this is manifested in the mail 
notification that's sent out as part of mail triggered via the "post-build 
actions" section.

Does anyone know if "BUILD_DURATION" parameter is available by any other 
name or this could be caused due to missing plugin?

As a workaround, I can record start and end times and do some math. But 
this step may have to repeated across 10+ jobs and, personally, I want to 
avoid such repetitive tasks.

Another option could be using email templates written in Groovy -- any 
pointers to this would be welcome too.

Ram

Sharing a tidbit of what I did earlier to avoid triggering fresh builds 
jobs for changes in Jenkinsfile -- you may need additional logic to process 
the changeset, i.e. checkout the repo, gather the list of changed files ( 
this will help to determine if the changeset includes only Jenkinsfile), 
and then take the necessary action.

In short:

The second (temporary) workspace is the area that's used by the pipeline to 
handle all of the code within the 'sh' step.

Based on what I analyzed, the pipeline creates a .sh file in that temporary 
workspace, the script's contents are what's there inside the 'sh' step. 
Apart from the shell script, in that temp workspace, there are few more 
files (in the tmp folder) for the purpose of pipeline durability.

HTH.

Not familiar with GitLab config options, so, pls ignore if this note is 
irrelevant.

Will it help if the user (that does the build, can clone the repo, etc.) as 
one of the members in the specific repo within GitLab?

Jenkins Scripted Multi-branch Pipeline: Is it possible to have different build numbering schemes?

[Ramanathan Muthaiah]

Hi,

Am looking at having different build numbering schemes - one for timer 
triggered and another for builds triggered via git events.

As of now, I cannot install any new plugin as that might force us to 
upgrade Jenkins -- ours is quite older version and the upgrade is long 
overdue.
However, am exploring the possibility of having this customization handle 
via Groovy code.

So, what's the need for different build numbering scheme?

a) Codebase (repo hosted in github enterprise) receives commits on 'master' 
-- this should generate artefacts. However, timer triggered build should 
not for this codebase.

b) We are running Jenkins v2.x Pipeline with multi-branch setup and shared 
library. So, essentially, 'master' branch shares the Groovy library with 
another 'dev' branch in the same code repo. This Groovy library (in 
scripted pipeline) triggers the build for both the branches at the 
specified time, does a branch check; if the branch is 'dev' proceed 
further, but will stop if the branch is 'master'. However, in the latter 
case, build number gets incremented and that's not the desired behavior 
(per project requirements).

c) Jenkinsfile in the codebase sets a bunch of params with default values 
using Groovy closure. This is picked by the Groovy library (i.e. 
vars/buildCodeArtefacts.groovy)

buildCodeArtefacts{
param1 = "value1"
VERSION = "0.2"
}



Are there better ways to handle this than the idea of different build 
numbering scheme?

Start simple, then expand. Also, I presume you should adjust the cmd, to be 
like, "curl . . . -X POST".

Avoid using "-s" option during the initial trials. man curl is your best 
help.

Remember, getting curl working from CLI and in an automated env like 
Jenkins involves several iterations, depending on the complexity (speaking 
from my personal experience).

Logging using fluentd, with Jenkins (stdout, stderr) running in a container

[Ramanathan Muthaiah]

Hey,

On a CentOS vm, am running fluentbit (as td-agent) configured with basic 
options.

1. Running a simple ubuntu container with a) /bin/bash or b) /bin/echo 
"Hello World" echoes the output (from the container) in the td-agent log 
at, /var/log/td-agent/td-agent.log

docker run -d -ti  --name  echome  ubuntu:latest  --log-driver=fluentd   --
log-opt  tag=docker.{{ID}}  /bin/bash

docker run -d -ti  --name  echome  ubuntu:latest  --log-driver=fluentd   --
log-opt  tag=docker.{{ID}}  /bin/echo "Hello World"


2. However, in my attempt to run Jenkins in a container, logs (from the 
running container) do not show up in the td-agent logs in '/var' folder.
docker run -d -ti  --name  cijenkins  jenkins/jenkins:lts  --log-driver=fluentd 
  --log-opt  tag=docker.{{ID}}  /bin/bash


Would appreciate any inputs or comments.

1) If you can 'ssh to the node', using the same credentials, can you 
checkout the repo ?

2) In the Git repo, if accessible via Github UI or some form of UI, does 
the user have necessary privileges to clone ?

3) Remember, when the build happens in the agent node, it runs as a user 
different from your user id.

Getting cause for branch indexing in multibranch pipeline

[Ramanathan Muthaiah]

Am referring to this API doc to find out which method should be used to 
identify the reason for a build job to be triggered.

http://javadoc.jenkins-ci.org/hudson/model/class-use/Cause.html

Would appreciate if anyone on this list could point me to the relevant 
method ?

For some strange reason, GHE org folder config (in prod Jenkins) does not 
have periodic triggering / scanning (that initiates branch indexing) but 
the detected repos have that option enabled !!!

How to know if the pull requests are trusted ?

[Ramanathan Muthaiah]

Hello,

We're running Jenkins v2.32.2 (agreed, it's very very old, but this is in 
the enterprise) and am trying to setup multibranch for one of Git repos 
(hosted in github enterprise - GHE).

For every build job, triggered by Jenkins multibranch, pipeline kicks in 
but Jenkinsfile changes in PR branch isn't picked but from 'master' !

I have searched thru' cloudbees knowledge base, and various other forums. 
GHE user, who created the PR, has 'write' access in that GHE repo.

Inspite of this config and setup, PR builds are falling back to Jenkinsfile 
from the 'master'. Is there a way to know what trust is lacking and how to 
fix this issue ?

Pick and choose the events to be sent over from GH to Jenkins. For the rest 
of the checks, you can write Groovy scripts.

If you need help, refer to doc on shared libraries -- with that, your 
Groovy code can scale and serve multiple projects, if they all follow the 
same workflow as you outlined.

Multibranch (or GHE organization, if you prefer) is the way to go for this, 
saves you from setting up that many projects for each branch. In GH, select 
all the events to be sent to your Jenkins.

If you choose multibranch, there will be additional steps in the branch 
selection, what to do with origin and fork PRs.

Please be considerate of the size of the error logs that you post ; trim 
them as you see fit, after initial troubleshooting at your end.

On a quick scan, there is no signature related to Jenkins, error is from 
some csproj.

How about like this ?

def tag = sh (returnStdout: true, script: "git describe --candidate=1 
--tags").trim() 
env.TAG = sh (returnStdout: true, script: "echo ${tag} | cut -d\'-\' -f 1").
trim()

I haven't tested this code though, so, cannot guarantee it's success or 
failure, you may want to tweak and customize according to your needs. But, 
it's worth looking at / using the 'sh' step's return status and output.

Remember to use them inside 'script' block if you're using Declarative 
syntax.

Have you looked at flow 
control, https://jenkins.io/doc/book/pipeline/syntax/#flow-control ?

Another option is to use 'when' 
directive, https://jenkins.io/doc/book/pipeline/syntax/#when

Can you try this in your pipeline script ?

withCredentials([[$class: 'UsernamePasswordMultiBinding', credentialsId: 
'jiracreds', usernameVariable: 'JIRAUser', passwordVariable: 'JIRAPwd']]) {
 withEnv(["JIRA_USERNAME=${JIRAUser}",
 "JIRA_PASSWORD=${JIRAPwd}",

   }
 }

Re: How to pass Jenkins env variables in SaltStack Jenkins plugin

[Ramanathan Muthaiah]

If you need to access environment variables in saltstack, aren't there any 
methods to access them.

I have not used saltstack but you should the tool's documentation to 
understand how to access env vars. Using such provision, you should access 
env var rather than passing to saltstack.

ECS slave to agent connection fails due to JNLP's SSL engine errors

[Ramanathan Muthaiah]

Hello,

In my AWS setup, we have two separate clusters – one for master, another 
for agent. But both are in same vpc, subnet, and have security group 
assigned. Other than this, there is no other fancy stuff going on here, 
like, ELB, SSL certs (all communication happens over http, its a private 
setup).


1) I have configured ecs plugin – jenkins agent cluster is used here with 
url pointing to private ip of master, added simple cloudbees template with 
task ARN and given the template a label that can be used in the pipeline.


2) When the pipeline is triggered, master, using the plugin config, spins 
up a new task dynamically and starts a container in one of the instances 
attached to agent cluster. But, the agent to master connection is broken 
with the error -- snippet of docker logs from the slave agent where the ecs 
task spins up a new container.

Take some time to look at the notes that shows up when you click on the 
question mark inside the blue colored circle (next to each and every option 
available in only UI). Side note, the matrix level can be set global 
security and at job or folder level too (if the project matrix plugin is

Thanks for the notes on deserialization. 

Immediately after posting my query to this forum, I  did few changes to the 
code, like, assigning null values to some of the variables.

This did solve the problem for me!

Groovy code in Pipeline and CPS trouble

[Ramanathan Muthaiah]

Hello All,

I have tested the below snippet of code in myjenkinsurl/script and it works 
fine.

However, same code (embedded or loaded via external Groovy code) in 
Pipeline workflow script fails, inspite of CPS annotation (with the 
stacktrace that's given after this code snippet) ?

NOTE:
First print statement in 'getjobName' function successfully matches the job 
(using regex).

#!/usr/bin/env groovy

import org.jenkinsci.plugins.workflow.job.*

@NonCPS
def getjobName(String job) {
for (item in Jenkins.instance.items) {
if (item =~ /metamon-alert-configs/ ) {
println item.getName()
jobname = item
}
}

for (build in jobname.Builds()) {
println build
}
}


node('master') {
stage('getlog') {
def jobname = getjobName("mon-alert-configs")
}
}


Reading (novice at it) the stacktrace suggests it's to do with 
serialization of variables but the annotation should take care of that, 
isn't it ?

an exception which occurred:

There are tons of Groovy scripts

To store cmd status or output, you should use sh(). You will find code

BTW, Jenkins Pipeline doc has step called, "findFiles" but there is nothing 
like, findbugs. Is that your custom function?

Yes, configure webhook in GH repository to send event related to Pull 
Request, if that's sufficient for your requirement. Select all the events 
(don't remember the exact name) if you have need for all the events to be 
passed to jenkins master.

NOTE:
Jenkinsfile may or may not need the property (related to github push) to be 
set. There were few threads in this group on this setting.

GitHub Branch Source plugin and pull requests from forked repos

[Ramanathan Muthaiah]

https://go.cloudbees.com/docs/cloudbees-documentation/cje-user-guide/index.html#_controlling_what_is_built

Documentation mentions that "By default, Jenkins will build any branches it 
finds in the “origin” repository (the actual repository found in your 
organization). Also, any pull requests that have been filed from “forks” 
(clones in user accounts) will also be built . . ."

In our setup, running Jenkins v.2.60.1 with this plugin v2.2.0, the latter 
usecase i.e. pull requests filed from forks is not triggering automatic 
builds -- user A forks a repo, commits his/her changes to 'master' in 
forked repo and then creates a pull request from the actual repo.

I hope this is valid use case. So, does anyone know why this fails ?

Pipeline property for GitHub PullRequest

[Ramanathan Muthaiah]

While regular GitHub PUSH event can be handled via this property setting in 
Jenkinsfile pipeline script, am interested to know if there is similar 
property for GitHub Pull Requests?

>>> pipelineTriggers([githubPush()])

Setup: 

Jenkins ver is @ 2.60.1, have webhook setup between GitHub Enterprise and 
Jenkins master.

Project is setup to trigger automatic build upon GitHub events (Push, PR), 
it is a regular pipeline job -- with regular Push event from GitHub, 
automatically fresh build job is triggered in the above setup, want to know 
if there is a similar way to handle PRs too via properties?

NOTE:
Am aware of other options that can be chosen while setting up project, 
like, GitHub organizational folder, MultiBranch Pipeline ; but, wanted to 
explore this PR topic with simple pipeline project setup in Jenkins.

[Resolved] : Github push event fails to trigger pipeline job in jenkins

[Ramanathan Muthaiah]

For the benefit of those who may come across similar issue, let me share 
some details of how this was fixed.

Internal Setup:

Jenkins instance is in cloud, from the cloud we have no direct connectivity 
to enterprise github server which is in a data center.
And, requests from Jenkins to github was routed via proxy in cloud.

Given this setup, we opted to go for AWS SNS + AWS Lambda solution.

Event Flow:
==
In Github repo, SNS topic is added and the payload of Github event is sent 
to Lambda which subscribes to SNS topic.
Lambda processes the payload and relays it to appropriate Jenkins master 
(multiple masters in cloud).

Problem:
===
However, PUSH event that reaches the master (correctly) was not triggering 
the job (both freestyle and pipeline).
It turned out be that github URL that reaches the master was not matching 
with URL set in the job config.

Recall from the setup section, Jenkins' communicates with the github server 
via the proxy.
It was this URL (pointing to the proxy) that was in the job but the event 
payload sent from github had different URL.

So, in the Lambda, we changed the URL to match with that of the proxy 
before relaying to Jenkins master.
Eventually, this did the trick and PUSH event was followed by poking of the 
job that resulted in triggering a fresh build of that job.

Overall, it was good learning experience.

Great news and thank you very much for sharing your findings.

In a fresh instance of Jenkins, with JJB 2.0.0.0b2 beta version, I reran
the script and it worked.

Why JJB project did not mention this issue in their project website [
https://docs.openstack.org/infra/jenkins-job-builde ] is surprising?

Jenkins behaviour with github webhook and github service

[Ramanathan Muthaiah]

Hi All,

Am working to setup webhook trigger between github enterprise and Jenkins. 

As part of this, enabled AWS SNS in Github repo and have Lambda subscribed 
to the AWS SNS topic. 
With this setup in place, on Jenkins side, in the job (where build should 
be triggered automatically) these two options were enabled.

"Github Project" 
"GitHub hook trigger for GITScm polling"

Is it correct to assume that with the service option enabled (with SNS in 
this case) and turning on these features in the specific job, will enable 
Jenkins to trigger the job when the event from Github is passed to the 
Jenkins server?

Or the two features will work only if webhook is enabled in github repo by 
setting the webhook URL, like, http://my-jenkins-server.com/github-webhook/?

Yes, the job is setup as pipeline style and that option (to trigger build 
on Github change) is enabled.

Are there any extra commands needed in the pipeline job to indicate that it 
should be triggered when github event occurs, like, commit or pull request?

I think it may be helpful to share details of the jenkins build job that's 
failing, info about usage of any special plugins.

Jenkins job builder -- Cannot create pipeline style jobs

[Ramanathan Muthaiah]

Hi All,

Pls bear with me for the lengthy post. I did go through the documentation 
(JJB) on how to create jobs of freestyle and pipeline style. 


With JJB installed in an Ubuntu box (running in Vagrant), I could create 
simple freestyle jobs. 

However, the same is not the case with simple pipeline jobs.


a) YAML code used to create pipeline job was based on the example in the 
section, “Pipeline as code” example", given here, 
https://docs.openstack.org/infra/jenkins-job-builder/project_pipeline.html


- job:






-job:

   name: JJB_OSFY

   project-type: pipeline

   sandbox: true

   pipeline-scm:

 scm:

  - git:

  url: https://github.com/mramanathan/OSFY.git

  clean: true

 script-path: Jenkinsfile



b) And the command tried to create pipeline job. Example code was stored in 
pipdemo.yaml

jenkins-jobs --conf server.ini update pipdemo.yaml


c) Output from the command:


++

INFO:root:Updating jobs in ['pipdemo.yaml'] ([]) 
INFO:jenkins_jobs.builder:Number of jobs generated: 1 Traceback (most 
recent call last): File "/home/ubuntu/.local/bin/jenkins-jobs", line 11, in 
sys.exit(main()) File

191, in main execute(options, config) File

line 356, in update_jobs 
self.parser.xml_jobs.sort(key=operator.attrgetter('name')) AttributeError: 
'NoneType' object has no attribute 'name'

+


d) FWIW, freestyle jobs were created using the same server.ini.


Any help would be appreciated.


NOTE:

Pls excuse me for posting this issue to this group. I did post it to JJB 
forum but haven't got any response until now, so, trying my luck here!

Re: Job Scheduling per 10 secs

[Ramanathan Muthaiah]

Hi ,

Freestyle or pipeline job configuration has few items that should satisfy 
what you're looking for.

1) Build Periodically

2) Do not allow concurrent builds.

Have you looked at them and tried to customize for your wants?

Re: Unable to connect to to the git repository, can any one please suggest what is wrong with the configuration

Adding to Victor's response, you may want to explore additional options 
available for checkout and cloning.

You should also evaluate if the git operations have to pass thru' proxy to 
complete repo checkout or cloning.

So, the URL with username and password is working (as expected).  If you 
are using withCredentials (meta-step ?) with credentials id, username and 
password are variables that help to store authentication info that can be 
used for git operations.

Have you looked at the console log, these values will be masked and 
displayed as asterisks ?

BTW, you should avoid having generic names, like, 'git' within dir() as 
seen in the code snippet shared by you.
It should reflect the purpose for which is meant for, like, it could be 
same as the repo name that you are trying to update with new commits.

Solution:

Retaining the same config values in the "properties" (step ?), I was able 
to get over this problem with only minor change to this:

text(defaultValue: 'us-west-2,us-west-1', description: 'AWS regions to copy 
AMI', name: 'ami_regions')

Removed the single blank space between the two values and double quotes at 
the start and end.

Pipeline build expects multiple values for a parameter

[Ramanathan Muthaiah]

Hello,

Am using parameters( [ . . . ] ) inside the pipeline script to define the 
values for the various parameters. These params are used while invoking 
packer tool.

properties([
  parameters([
string(name: 'region',  defaultValue: 'us-west-2',   description
: ''),
text(defaultValue: '"us-west-2, us-west-1"', description: '', name: 
'ami_regions')
  ])
])


For the packer tool, among other variables, I need to pass multiple region 
names, like this,

packer -var ami_regions="us-west-2, us-west-1" . . . 

Am able to access them like, ${params.ami_regions} but then the double 
quote is missing and the input to packer cmd is partial i.e. us-west-1 is 
missed out.

Does anybody know why is this ? And, is there a better way to handle this, 
via some groovy script embedded within the pipeline ?

Regd item 2), returnStatus will return the execution completion status of 
commands enclosed within "script: " 

It can be either 127 (if the command is not found) or 1 for failed valid 
command or 0 for valid command that has been executed successfully.

Pipeline build fails using "withAWS"

[Ramanathan Muthaiah]

Hello,

Pls excuse for the lengthy post.

Am looking to make use of IAM roles in the given AWS account (jenkins 
master runs in the same account) and run packer build to generate AMI. 
This is to avoid storing / using AWS keys in Jenkins master.

For this purpose, I wanted to make use of this plugin, 
https://github.com/jenkinsci/pipeline-aws-plugin

Jenkins master is at v2.32.3

This is the primitive pipeline code which am attempting but it fails with 
error pointing to secure token being non-available.

Has anyone got this plugin working with pipeline script ?

node {
stage('aws') {
withAWS(role:'jenkins-ec2-master') {
  // awsIdentity()
}
}
}


For your ref, attached snippet of errors from build console log.

Jenkins pipeline build fails to run script inside Docker container

[Ramanathan Muthaiah]

Hello All,

Using standard + Pipeline + Docker plugins in Jenkins v2.53, am trying to 
run flake8 within a Docker container environment.

1. Jenkins master is running in a Vagrant VM and there is no dedicated 
agent as this is meant for experimentation and learning purposes.

2. Docker toolbox is installed on the Jenkins master and pipeline build is 
set to run in the master.

3. In the Jenkins master:

ubuntu@ubuntu-xenial:~$ grep 112 /etc/passwd
uuidd:x:108:112::/run/uuidd:/bin/false
jenkins:x:112:117:Jenkins,,,:/var/lib/jenkins:/bin/bash


4. via pipeline, with Dockerfile as input, pipeline build is able to create 
image.

jenkins@ubuntu-xenial:~$ docker images flake8-node 
REPOSITORY  TAG IMAGE ID
CREATED SIZE
flake8-node latest  7c6e568293f322 hours 
ago277 MB


5. Manually launched the docker container using the built image to check 
"jenkins" user:

jenkins@ubuntu-xenial:~$ docker run -ti flake8-node:latest
. . . . 
. . . .
jenkins@513b3c3988ca:/data$ id
uid=1000(jenkins) gid=1001(jenkins) groups=1001(jenkins),1000(docker)

However, during pipeline build, while attempting to execute flake8 shell 
script using "docker.inside", build fails with this error:

*docker run -t -d -u 112:117 args . . . . . . . *
. . . . . . . . . . . 
. . . . . . . . . . .

*"fatal: unable to lookup current user in the passwd file: no such user"*
Mining through the archives, I found this thread related to this issue but 
there isn't any conclusion.

https://groups.google.com/forum/#!searchin/jenkinsci-users/docker$20containers%7Csort:relevance/jenkinsci-users/dMxdQrJJAOg/ueBtrl1LCQAJ

Any ideas welcome !!!

Re: Jira/Jenkins integration Plugins

[Ramanathan Muthaiah]

Hi Marlene,

I have not used JIRA plugin in Jenkins but aware of Python library that 
allows CLI interaction to JIRA.

My experience with jira-python module is pretty limited but it looks 
interesting.

Another way to get this done (if you have done prior Python programming) is 
to use REST APIs available in Jenkins.

It's quite fun to deep dive and learn.

Howto integrate OWASP dependency check plugin in Jenkins Pipeline ?

[Ramanathan Muthaiah]

Hi ,

After reading thru' OWASP dependency check plugin wiki and JIRA issues, I 
could not find examples of simple usage of this plugin in Jenkins Pipeline 
with the exception of this code snippet (sourced from one of the PR 
conversations in this plugin's GH page):

step([$class: 'DependencyCheckPublisher'])

I would like to collect data from OWASP dependency check by scanning mostly 
Python-ish codebase.

Has anyone tried this combination i.e Jenkins Pipeline + OWASP dependency 
check ?

NOTE:
There is not much documentation available here too, 
https://github.com/jenkinsci/dependency-check-plugin

Appreciate any pointers on this topic.

This issue is solved. Usage of incorrect syntax (marked in italics) was 
causing Pipeline build errors.

node('master') {
  stage(' == Capitals == ') { 
 configFileProvider([configFile(*fileId*: 
'', variable: 'capitals_info')]) {
 echo " == content of json cfg == "
 sh "cat $capitals_info"
 }
  }
}

Dominik suggested he will make improvements to display a better error 
message.

It will help if you can list what did you try and what did not work

Two (actually three) possible options:

1) Explore "Managed Scripts" plugin (I suppose this supports only shell 
scripts) alongwith Config File Provider plugin.

2) If you have Pipeline plugin installed, then these Python scripts can be 
invoked using step, "sh" but this will demand your scripts in version 
control.

3) If the Jenkins job is a freestyle project, then the entire script can be 
added as a 'build step' ; but then, every change to the build script (for 
bug fixes or new improvements), job needs to be modified and the script 
content should be replaced.

Jenkins Pipeline build error: Failed to prepare configFileProvider step

[Ramanathan Muthaiah]

Hello All,

Need help with pipeline build error in this setup:

Jenkins v2.36 with standard pipeline plugins + configFileProvider plugin 

Here is the content of Jenkinsfile, pipeline script:

node('master') {
 stage(' == Capitals == ') {   
   configFileProvider([configFile(field: 
'capital_jsoncfg', variable: 'capitals_info')]) {
echo " == content of json cfg == "
sh "cat $capitals_info"
 }
   }
 }

And, the pipeline build fails with this error (followed by verbose output):

java.lang.IllegalArgumentException: Failed to prepare configFileProvider step
at 
org.jenkinsci.plugins.workflow.cps.DSL.invokeDescribable(DSL.java:315)
at org.jenkinsci.plugins.workflow.cps.DSL.invokeMethod(DSL.java:129)
at 
org.jenkinsci.plugins.workflow.cps.CpsScript.invokeMethod(CpsScript.java:108)
at groovy.lang.GroovyObject$invokeMethod.call(Unknown Source)


Read thru' the example given here:
https://wiki.jenkins-ci.org/display/JENKINS/Config+File+Provider+Plugin

Searched this forum and stack overflow for possible clues but no successful 
hits until now.

Does anyone know what's wrong with the pipeline script ?

P.S :

In the same setup of Jenkins master, I have a freestyle job configured to 
use the same json cfg, in that job there are no such issues. 
Simple shell command, like, cat-ing the contents of JSON cfg works in the 
freestyle job.


TIA,
/Ram

If I were you, would be doing these to check this error:

Build job is executed as 'what user', determine from the build logs.

On the Linux box, if I can connect via ssh (independent of Jenkins), as 
what user PeopleSoft commands can be run ?

Not sure if this is needed.

It would help if you could share details on any scripts you use while the 
job is tirggered ? like, using  any shell or pipeline scripts or ansible 
playbooks ?

[Ram] : I did start writing the library with this separation ; after

repo. 

Than, make sure you know what version of the library you are using:

With these changes, global shared libs are now usable from the Jenkinsfile.

2. Using in-line editor

Choose the "Pipeline Script" option, editor should show up on the same UI 
page.

3. Pipeline Script from SCM

And, then there is the third option to be more specific with SCM (git / 
subversion and provide details of repo, credentials, etc.) if you choose, 
"Pipeline Script from SCM"

However, all this depends on the version of Jenkins and the plugins 
installed.

Create Jenkinsfile and store it in the root of your repo. Setting,

Are you looking to do remote trigger the build for a particular project / 
job setup in Jenkins ?
If so, then look for "Trigger build remotely (e.g. scripts)" in the job 
configuration.
Remember this will expect you to pass the token of the user.

Trouble using shared pipeline libraries

[Ramanathan Muthaiah]

Am running Jenkins v2.3x with Pipeline plugin running at v2.x

In the repo root, I have a Jenkinsfile from which shared library is meant 
to be used.

repo_root / 
 |_ Jenkinsfile
 |
 |_ vars /
 |
 | buildUtils.groovy

Within the buildUtils.groovy, this is the code snippet:

#!groovy

def call(body) {

def config = [:]
body.resolveStrategy = Closure.DELEGATE_FIRST
body.delegate = config
body()

node('linux') {
checkout scm
def url = "https://github.com/jenkinsci/${config.name}-plugin.git";
echo " == URL with repo name == "
echo "${url}"
}
}


With this setup in place, running Jenkins build job for this repo, fails 
with this error:

[Pipeline] End of Pipelinejava.lang.NoSuchMethodError: No such DSL method 
'buildUtils' found among steps 

I have been scourging forums here, in SO, in Google but no real solutions seem 
to 
be available (atleast, it seems to escape my eyes).

What's going wrong here ?

TIA,
/Ram

Using Rundeck as a step in Pipeline script ?

[Ramanathan Muthaiah]

Am experimenting with Jenkins v2.36 and Rundeck v2.x ; have installed

For few days, I have been Googling to find / know how to use Rundeck within

So far, have not found any source on the Net on this topic. Does anyone in 
this group have experience ?

P.S:
As a fallback option, installed Rundeck CLI and wrote a short shell script 
invoked from Pipeline script.
