currentBuild.getBuildCauses(type) fails when type is a cause contributed by a plugin

Issue Type:	Bug
Assignee:	Unassigned
Components:	workflow-support-plugin
Created:	2018-11-16 16:57
Environment:	Jenkins ver. 2.138.3 workflow support 2.22 all latest plugin uploads as of issue creation
Priority:	Major
Reporter:	Mike Kobit

currentBuild.getBuildCauses(type) was added in 2.22 which seems to work for Jenkins built-in causes but fails when trying to look-up causes contributed by plugins.

Example:

 
                                                                currentBuild.getBuildCauses('org.jenkinsci.plugins.workflow.cps.replay.ReplayCause')

Fails with:

 
                                                                java.lang.ClassNotFoundException: org.jenkinsci.plugins.workflow.cps.replay.ReplayCause
	at jenkins.util.AntClassLoader.findClassInComponents(AntClassLoader.java:1374)
	at jenkins.util.AntClassLoader.findClass(AntClassLoader.java:1327)

        ... 
                                                            

My presumption is that it is not using the correct classloader.

currentBuild.getBuildCauses(type) fails when type is a cause contributed by a plugin

Change By:	Mike Kobit

{{currentBuild.getBuildCauses(type)}} was added in 2.22 which seems to work for Jenkins built-in causes but fails when trying to look-up causes contributed by plugins.

Example - replay after building first time with failure to see echo'd output shown below :
{code:java}
echo "${ currentBuild. buildCauses}"
currentBuild. getBuildCauses('org.jenkinsci.plugins.workflow.cps.replay.ReplayCause')
{code}
Fails with:
{noformat}
[Pipeline] echo
[[_class:hudson.model.Cause$UserIdCause, shortDescription:Started by user anonymous, userId:null, userName:anonymous], [_class:org.jenkinsci.plugins.workflow.cps.replay.ReplayCause, shortDescription:Replayed #9]]
[Pipeline] End of Pipeline
