With a matrix job, by default for a SCM checkout, this step is exectued:

• at job level (before each axe)
• for each axe
  All source code are gathered in a single directory: the workspace

Can you confirm it the same behaviour for the Clearcase Jenkins plugin?

EnvInject variables are only injected at the moment for each axe.
Therefore, you're right there is an issue.

Code changed in jenkins

Log:
Proposal to JENKINS-15507

I don't know why I previously excluded the environment injection at the matrix job level.
However, I added it.
Please could you check if this new version suit you (about an official release)?
The snapshot version can be found here:
https://buildhive.cloudbees.com/job/jenkinsci/job/envinject-plugin/59/org.jenkins-ci.plugins$envinject/

Can you please share when new version of envinject with this fixed issue will be realease officially!!!

Available from EnvInject 1.73

Reopening/Bug seen in 1.73 - 1.88

• We've been stuck at EnvInject version 1.72 for the past year.
• Using SharedObjects 0.44
• Using Rebuilder 1.20

Simple usage scenario to recreate bug

• Create a matrix job with one user-defined axis named SERVICE_NAME; values are A B C
  • check : Run each configuration sequentially

• Rebuild settings
  • check: Prepare an environment for run
  • check: Keep Jenkins env var's
  • check: Keep Jenkins build var's
  • Evaluated Groovy script

    def env = [:]
    if ( SERVICE_NAME == 'C' ) {
       env = ["ADDITIONAL_SETTINGS" : " xyz " ];
    } else {
       env = ["ADDITIONAL_SETTINGS" : "" ];
    }
    

Results

1.72

• Each axis job runs successfully
• Example log for SERVICE_NAME = C

• Parent matrix job fails and thus no axis children jobs are executed.

• In the failed job above, the Evaluated Groovy Script doesn't recognize the axis value SERVICE_NAME as an exported property/env var.

Is there any progress on this issue? I am unable to use Git Publisher to create a tag with tagname from an environment variable I have injected into the build process.

Resolution is still Unresolved, but the latest version of this plugin does work (partly). Environment variables defined in "Prepare an environment for the run" are available for matrix parent and all axis. However environment variables defined in "Inject Environment Variables" Build step is not available on matrix parent.

I'm currently facing this issue with Jenkins 1.643 and EnvInject 1.92.1 . I'm happy to provide debugging data if that would be useful.
