Hudson build does not work with FATAL: null java.lang.AbstractMethodError

Question

I installed Hudson on Ubuntu and I am using the git plugin. Git integration and a simple shell script I execute as a build step, it seems to work fine, but I get the following error and the build fails:

FATAL: null java.lang.AbstractMethodError at hudson.model.AbstractBuild.getCulprits(AbstractBuild.java:278) at hudson.model.AbstractBuild.getCulprits(AbstractBuild.java:275) at hudson.model.AbstractBuild$AbstractRunner.post(AbstractBuild.java:565) at hudson.model.Run.run(Run.java:1386) at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:46) at hudson.model.ResourceController.execute(ResourceController.java:88) at hudson.model.Executor.run(Executor.java:145) 

I have no action after the build.

Answer 1

I have the same exception, and the reason in my case was incompatibility when using hudson 2.0.0 and hudson git plugin 2.0.1. Either upgrade your hudson server, or remove the git plugin and manually install the older git plugin from http://hudson-ci.org/downloads/plugins/git/2.0.0/ .
