John Zila created an issue   Jenkins / JENKINS-41207 NullPointerException in Github branch source plugin after upgrading Issue Type: Bug Assignee: Unassigned Components: github-branch-source-plugin Created: 2017/Jan/19 8:53 AM Environment: Jenkins 2.41, all current SCM/Github/Pipeline plugins in the experimental repo, according to https://jenkins.io/blog/2017/01/17/scm-api-2/ Priority: Major Reporter: John Zila I upgraded according to the guide, and suddenly all my multibranch jobs are gone from Jenkins. I look at the logs and see this for each of my job types: Failed Loading item kbfs-server java.lang.NullPointerException at jenkins.branch.MultiBranchProject.onLoad(MultiBranchProject.java:171) at hudson.model.Items.load(Items.java:372) at jenkins.model.Jenkins$17.run(Jenkins.java:3061) at org.jvnet.hudson.reactor.TaskGraphBuilder$TaskImpl.run(TaskGraphBuilder.java:169) at org.jvnet.hudson.reactor.Reactor.runTask(Reactor.java:282) at jenkins.model.Jenkins$7.runTask(Jenkins.java:1066) at org.jvnet.hudson.reactor.Reactor$2.run(Reactor.java:210) at org.jvnet.hudson.reactor.Reactor$Node.run(Reactor.java:117) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) I can recreate the jobs with the same names, upon which Jenkins reindexes from GitHub, "finds" the jobs for still-open branches and PRs, including their whole histories, and everything works as it should. But then when I restart Jenkins they're all gone again, and I have to do the whole dance again. As you can imagine, this is incredibly frustrating and a terrible time sink. What can I do to fix this, short of creating brand new jobs with lost history? I've tried to downgrade but the dependencies are too entangled. I have a backup of my plugin directory and plugin configs, but I'd really rather avoid regressive steps like that.
