How to distinguish assembly triggers in a Jenkins pipeline

Question

I hope to add a conditional step to my Jenkinsfile, which starts depending on how the assembly was created. We are currently configured so that assemblies are either started using:

• changes to our git repository, which is selected when indexing branches
• the user manually starts the build using the 'build now' button in the user interface.

Is there a way to start different transition steps, depending on which of these actions caused the assembly?

Answer 1

The following code should work to determine if the user has started a pipeline or timer / other trigger:

def isStartedByUser = currentBuild.rawBuild.getCause(hudson.model.Cause$UserIdCause) != null

2.22 (2018 02) API . JENKINS-41272.

currentBuild currentBuild :

getBuildCauses

• JSON-

- getBuildCauses(String causeClass)

• , Cause JSON- , , JSON-, .

, :

echo "${currentBuild.buildCauses}" // same as currentBuild.getBuildCauses()
echo "${currentBuild.getBuildCauses('hudson.model.Cause$UserCause')}"
echo "${currentBuild.getBuildCauses('hudson.triggers.TimerTrigger$TimerTriggerCause')}"

:

[Pipeline] echo

Answer 5

Jenkins Pipeline currentBuild.rawBuild :

// started by commit
currentBuild.getBuildCauses('jenkins.branch.BranchEventCause')
// started by timer
currentBuild.getBuildCauses('hudson.triggers.TimerTrigger$TimerTriggerCause')
// started by user
currentBuild.getBuildCauses('hudson.model.Cause$UserIdCause')
