I am unable to read my custom environment variables from a specific
projects previous builds.
stage("Test") {
node("master) {
env.TEST = "Hello World"
}
}
stage("Previous") {
final def lastBuild = currentBuild.rawBuild.getPreviousBuild()
final def upstreamEnv = lastBuild.getEnvironment(manager.listener)
final def test = upstreamEnv['TEST']
println "TEST="+test
}
TEST=null
1) Is this a bug?
2) Am I doing something wrong getting the environment variable from the
previous build?
Perhaps I must use a different listener than manager.listener, but I am
not sure how to get one.
3) Is it as intended, in other word it is not implemented, storing custom
build environment variables to the build?
The following work
def previousBuild = currentBuild.previousBuild
def upstreamEnv = previousBuild.getBuildVariables()
final def test = upstreamEnv['TEST']
However I was using currentBuild here as an example. I am actually getting
the previous build of a different project than the currentBuild project.
A WorkflowRun does not have a getBuildVariables() which RunWrapper does.
def getPreviousReleaseBuild(jenkinsProjectName) {
def releaseBuild = null
final def jenkinsInstance = jenkins.model.Jenkins.getInstance()
final def jenkinsProject = jenkinsInstance.getItemByFullName(
jenkinsProjectName)
if (jenkinsProject != null) {
final def job = jenkinsProject.getAllJobs().first()
final def lastBuild = job.getLastBuild()
final def upstreamEnv = lastBuild.getEnvironment(manager.listener)
final def buildRelease = upstreamEnv['BUILD_RELEASE']
if (buildRelease) {
releaseBuild = lastBuild
}
}
return releaseBuild
}
I have also tried
lastBuild.getEnvVars()
lastBuild.getCharacteristicEnvVars()
But neither of these contains the build environment variable I created in
the pipeline script.
I could set up BUILD_RELEASE as a build environment property that I then
can access with lastBuild.getEnvVars()
properties([
parameters([
booleanParam(defaultValue: false, description: 'Build a release'
, name: 'BUILD_RELEASE')
])
])
However I do not want this build environment variable exposed to users when
they "Build with Parameters".
