git plugin 4.4.3
Some of our builds started to fail during a checkout step with the following error:
java.lang.NullPointerException at hudson.plugins.git.GitSCM.createClient(GitSCM.java:852) at hudson.plugins.git.GitSCM.createClient(GitSCM.java:833) at hudson.plugins.git.GitSCM.checkout(GitSCM.java:1240) at org.jenkinsci.plugins.workflow.steps.scm.SCMStep.checkout(SCMStep.java:125) at org.jenkinsci.plugins.workflow.steps.scm.SCMStep$StepExecutionImpl.run(SCMStep.java:93) at org.jenkinsci.plugins.workflow.steps.scm.SCMStep$StepExecutionImpl.run(SCMStep.java:80) at org.jenkinsci.plugins.workflow.steps.SynchronousNonBlockingStepExecution.lambda$start$0(SynchronousNonBlockingStepExecution.java:47) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) Finished: FAILURE
The code, that used to work in the past, was configured (for some reasons) as follow:
stage("Checkout branch") { checkout scm // Specific configuration to clone the branch into a dedicated local branch. checkout([$class : 'GitSCM', branches : [[name: "*/${env.BRANCH_NAME}"]], extensions: [[$class: 'LocalBranch', localBranch: env.BRANCH_NAME]] ]) }
It looks like this was introduced by a recent change in https://github.com/jenkinsci/git-plugin/pull/931, specifically in the following changeset: if getUserRemoteConfigs() doesn't return any "user remote config", then chooser stays null and the call to chooser.getGitTool() fails with a NullPointerException.
