How can pipelines unset environment variables

[Randall Becker]

I have a situation where I need to run a pipeline with a reduced set of 
environment variables. The build environment has a limit of the total size 
of the environment and Jenkin's contribution is causing an overflow to that 
limit. Is there a way to unset variable in pipelines as could be done in a 
single step in freestyle projects?

Re: SharedLibrary doesn´t allow git parameter to fetch all branches

[Ganesan Srinivasan]

Check this link https://plugins.jenkins.io/git-parameter/

Git parameter doesnt know from which repo(shared repo or project repo), it 
fetches the branch from shared repo. Follow the below steps to solve this 
issue

If in the task are defined multiple repositories, this option specifies 
which the repository is taken into account on getting data.
*If the option is not defined, is taken a first defined repository.*
This option is a regular expression, which is compared to the 'Repository 
URL'.

You can define the multiple SCM for few way, you can use Multiple SCMs 
Plugin , 
specified 
many 'Repository URL' in one SCM  or define them in pipeline.

Consider an example based on two repositories:

   - https://github.com/klimas7/exampleA.git
   - https://github.com/klimas7/exampleB.git


Pipeline: Complex example

pipeline {
agent any
parameters {
gitParameter branchFilter: 'origin.*/(.*)', defaultValue: 'master', 
name: 'BRANCH_A', type: 'PT_BRANCH', useRepository: '.*exampleA.git'
gitParameter branchFilter: 'origin.*/(.*)', defaultValue: 'master', 
name: 'BRANCH_B', type: 'PT_BRANCH', useRepository: '.*exampleB.git'

}
stages {
stage('Example') {
steps {
git branch: "${params.BRANCH_A}", url: 
'https://github.com/klimas7/exampleA.git'
git branch: "${params.BRANCH_B}", url: 
'https://github.com/klimas7/exampleB.git'
}
}
}
}

Hope this solves the issue
