Tweet<\/a><\/div>\n\n

I’m attempting to obtain a Git Repo URL from a Jenkins Change set in a Groovy Scripted Pipeline, but I keep running into the same issue: the browser<\/code> property (obtained via .getBrowser()<\/code>) on my hudson.plugins.git.GitChangeSetList<\/code> object is undefined.<\/p>\n\n\n\n

I’m running the below code (with inline “status comments”) from the Jenkins groovy script console in an attempt to extract the RepoUrl from Chagesets in a Jenkins Multi branch groovy scripted pipeline:<\/p>\n\n\n

\ndef job = Jenkins.instance.getItem("MyJenkinsJob") \ndef branch = job.getItems().findAll({ \n            item -> item.getDisplayName().contains("Project\/CreateChangeLogs")\n        })\n\nprintAllMethods(branch[0].getFirstBuild()) \/\/this works, and is a org.jenkinsci.plugins.workflow.job.WorkflowRun\n\ndef builds = branch[0].getBuilds()\ndef currentBuild = builds[0]\n\ncurrentBuild.changeSets.collect { \n  printAllMethods(it) \/\/ this works too, and is a hudson.plugins.git.GitChangeSetList.\n  \/\/ enumerated methods are equals(); getClass(); hashCode(); notify(); notifyAll(); toString(); wait(); createEmpty(); getBrowser(); getItems(); getKind(); getRun(); isEmptySet(); getLogs(); iterator(); \n\n  it.getBrowser().repoUrl \/\/ this fails\n  \/\/ the error is java.lang.NullPointerException: Cannot get property 'repoUrl' on null object\n}\n<\/pre><\/div>\n\n\n
I found the utility class for PrintAllMethods here (https:\/\/bateru.com\/news\/2011\/11\/code-of-the-day-groovy-print-all-methods-of-an-object\/):<\/p>\n\n\n
\n  void printAllMethods( obj ){\n    if( !obj ){\n        println( "Object is null\\r\\n" );\n        return;\n    }\n    if( !obj.metaClass && obj.getClass() ){\n        printAllMethods( obj.getClass() );\n        return;\n    }\n    def str = "class ${obj.getClass().name} functions:\\r\\n";\n    obj.metaClass.methods.name.unique().each{ \n        str += it+"(); "; \n    }\n    println "${str}\\r\\n";\n}\n<\/pre><\/div>\n\n\n
The API spec for GitChangeSetList<\/a> indicates that in extends hudson.scm.ChangeLogSet<\/a> which implements getBrowser()<\/code>, so the call should<\/em> be valid.<\/p>\n\n\n\n
Additionally, the source for GitChangeSetList<\/a> invokes the super()<\/code> constructor with the passed browser<\/code> object.<\/p>\n\n\n\n
At this point, I’m probably going to continue diving through the source code until I figure it out. <\/p>\n\n\n\n
It looks like this is a documented issue with Jenkins: https:\/\/issues.jenkins-ci.org\/browse\/JENKINS-52747<\/p>\n\n\n\n
