[JIRA] (JENKINS-50418) when {branch} stage conditional regression

Issue Type:	Bug
Assignee:	Unassigned
Components:	pipeline
Created:	2018-03-27 03:00
Environment:	Jenkins 2.112 Pipeline: API 2.26 Pipeline: Model API 1.2.7
Priority:	Minor
Reporter:	Eric Nelson

The when branch conditional seems to still be broken. Similar to ~~JENKINS-41012~~. In this case we are using GitHub with webhooks to trigger a build. Following the good test code in 41012 I tested with the following.

Results - I get echo expression and echo env, but branch is always skipped.

Test pipeline code stage is:

 
                                                                stages {
stage('test condition: expression') {
when {
expression {
return env.GIT_BRANCH == "origin/master"
}
}
steps {
sh 'echo "expression"'
}
}

stage('test when: env') {
when {
environment name: "GIT_BRANCH", value: "origin/master"
}
steps {
sh 'echo "env"'
}
}

stage('test when: branch') {
when {
branch "master"
}
steps {
sh 'echo "branch"'
}
}
}

Re: when {branch} stage conditional regression

The branch conditional is checking against the more generalized BRANCH_NAME environment variable, which is only set for multibranch Pipelines. Is this on a multibranch Pipeline or just a standalone Pipeline job?

Re: when {branch} stage conditional regression

This one is a stand alone pipeline job. Which explains why when I checked BRANCH_NAME it also did nothing.

Is there a recommendation for branch checking in stand alone pipeline jobs?
