Jenkins / JENKINS-38763 NPE while loading build with workflow job Issue Type: Bug Assignee: Unassigned Components: workflow-job-plugin Created: 2016/Oct/05 11:39 PM Priority: Major Reporter: olamy I have a plugin https://github.com/olamy/loadgenerator-plugin. The pipeline generate a NPE (because of lazyLoading I guess). Is there any way to avoid that?

Jesse Glick resolved as Cannot Reproduce

The buildMixIn should be initialized in all usage modes. If it is unset, something is deeply wrong with the Jenkins item tree. Any known way to reproduce from scratch?

Re: NPE while loading build with workflow job Resolved? really I'm reproducing that everyday until the first run of the project. The code plugin is here: https://github.com/olamy/loadgenerator-plugin Line https://github.com/olamy/loadgenerator-plugin/blob/master/src/main/java/com/webtide/jetty/load/generator/jenkins/LoadGeneratorProjectAction.java#L66 I have added an ugly workaround to prevent NPE. Well after the job has been executed, it works again and I can see previous results. Not a big problem but not really convenient when developing the plugin and restarted very frequently (hpi:run)

Re: NPE while loading build with workflow job I know nothing about the thing you are pointing to. Are there specific instructions to reproduce the problem from scratch?

Re: NPE while loading build with workflow job

This is a plugin I'm hacking and I got the issue with. By the way the issue happen with non pipeline project as well. I have created a sample plugin to reproduce. https://github.com/olamy/JENKINS-38763 use mvn hpi:run Use this plugin as a build step. Run one build. Now restart hpi:run then go to the project page see the logs. Run the project once again no more NPE. Caused by: java.lang.NullPointerException at hudson.model.AbstractProject._getRuns (AbstractProject.java:954) at hudson.model.AbstractProject._getRuns (AbstractProject.java:145) at hudson.model.Job.getBuilds (Job.java:683) at org.olamy.jenkins.foo.FooProjectAction.getData (FooProjectAction.java:37) at org.olamy.jenkins.foo.FooProjectAction.doTrend (FooProjectAction.java:32) I hope it help to reproduce.

Jesse Glick resolved as Not A Defect

The mistake is in your sample plugin. FooProjectAction.project should be made transient and initialized by implementing RunAction2.
