Jenkins Git Environment variables not set in Pipeline

问题

I am trying to read some environment variables in Jenkins pipeline script that should be set by Git plugin, but it seems they are not set, because when I tried to use in script its value is empty string and also if I use sh 'printenv' I can see that they are not set.

Probably I am missing something but I cannot find what.

Any idea?

Per this page:

http://JenkinsURL/pipeline-syntax/globals:

SCM-specific variables such as GIT_COMMIT are not automatically defined as environment variables; rather you can use the return value of the checkout step.

This is supposed to be resolved in Jenkins 2.60, I believe:

https://plugins.jenkins.io/pipeline-model-definition

See the item for JENKINS-45198

You can workaround by running the appropriate git commands in a shell and assigning them to a variable:

GIT_REVISION = sh( script: 'git rev-parse HEAD', returnStdout: true )

In a Declarative pipeline, you will have to wrap this in a script{} block, and probably declare the variable outside of your pipeline to get the appropriate scope.
