Re: Jenkinsfile Accessing variables from shared libraries
Hi,
First, if you want "echo", you could just use echo without the sh :
echo "hello"
Then, if you want to print a variable in the echo, use this syntax :
echo "hello ${myGroovyVariable}"
You must use double quote, if you use single quote the echo will print
*exactly* what you have written

Hello there
Maybe this is a very basic question, but am not being able to access a
global variable
from a shared library from a Jenkinsfile
under vars I defined something like this
globalVars.groovy
class Vars () {
def CustomMessage = "This is a new deployment"
}
from my Jenkinsfile
library identifier: 'globalVars@master', \
retriever: modernSCM([$class: 'GitSCMSource', \
credentialsId: 'tfsservice', \
remote: 'http://myrepo.com', \
traits: [gitBranchDiscovery()]])
pipeline {
stages {
stage('Do Some Stuff') {
steps {
script {
sh 'echo ${CustomMessage}'
}
}
}
}
}
But the above returns nothing, what am I doing wrong?
Thanks

Re: Jenkinsfile Accessing variables from shared libraries
Hello
Is there a way to access those variables from as sh command from the script
section?
for example this works:
script {
echo GlobalVariables.MyVariable
}
but the same with sh does not, that just echos GlobalVariables.MyVariable
and not the variable content.
script {
sh ' echo GlobalVariables.MyVariable'
}
Thanks

Hello
Defining a global class worked for me, at least did what I wanted to do,
Thanks you very much for your time and support

Re: Jenkinsfile Accessing variables from shared libraries
Hi,
I think you should not use global variables at all : only global functions.
Trust me : you don't need global variables :)
To use global functions :
# /vars/myGlobFunc.groovy
def call() {
//
}
// This way you can call you function directly in "steps" if you are in
declarative pipeline, from anywhere in scripted
// This function has access to other global methods
# Or this way, in /vars/myClass.groovy :
def myGlobFunc.groovy {
// ...
}
return this
// myClass.myGlobFunc()
// This function has also access to other global methods because of this
special class declaration
// But you cannot call this from steps in declarative, you must be inside
script
But if you really want global variables, I would recommand to use a single
object containing what you need and give this object to people who need it,
for example a class or a map :
def myVars = [:]
myVars['myGlobVar'] = 'hello'
pipeline {
// ...
aFunction(myVars)
}
# But if you really really want global, just remove the "def" :
myVars = [:]
myVars['myGlobVar'] = 'hello'
pipeline {
// ...
aFunction() // myVars can be read in this function
}
// But I thihnk this is a bad code
Another way is to use static field of class, but it is also a bad pratice
to use static field if you want them mutable.
You could also just try to use the existing global var "env". This is a
clean solution, but you must only use text values.
env['myGlobVar'] = "hello"
echo env.myGlobVar
Good luck

Re: Jenkinsfile Accessing variables from shared libraries
In my case, I do the following. I have a GlobalVars.groovy file with below
content.
#!/usr/bin/env groovypackage com..;public
class GlobalVars { static String myVar = ""}
Then in my Shared Library class, I use it like below.
GlobalVars.myVar = ""
Try it like this and check. Here, I have declared the class as Public
and the variable as static. That's the only difference.
Regards,
Venkatesh

Re: Jenkinsfile Accessing variables from shared libraries
I see several problem
1. using ' will not expand the parameters is your call should be sh
"echo ${CustomMessage}"
2. CustomMessage is declared within the class Vars(), so you cannot
access it
You could implement a getter an then do something like this "echo
${globalVars.getCustomMessage()}"
Maybe others have better ideas...?
