java.lang.RuntimeException

There are no available Samebug tips for this exception. Do you have an idea how to solve this issue? A short tip would help users who saw this issue last week.

  • From Hudson 1.374, JDepend plugin breaks generation of "build.xml" for every build which eventually makes build unusable and it gets removed from history when hudson service is restarted/reloaded. We use hudson to do CI of our PHP based projects (I am not java guy, so forgive me if I could not provide exact details.). We use JDepend 1.2.2 plugin to generate JDepend report for hudson from generated jdepend.xml which gets created during the build. We generate that file using Phing (which has a task to generate JDepend file.) + PHPDepend softwares. From version 1.374, JDepend plugin has stopped to generate report from file and gives following errors in hudson's log file: =========================================================================

  • Hudson fails to serialize the build file after the build when I use the gerrit-trigger plugin, and gerrit is not updated build results. Although this error appears to be in the git data, the other jobs here that use the git plug without gerrit trigger don't have this problem, so perhaps I've just configured this job incorrectly. The other gerrit plugin doesn't have this issue, either.

  • Hudson fails to serialize the build file after the build when I use the gerrit-trigger plugin, and gerrit is not updated build results. Although this error appears to be in the git data, the other jobs here that use the git plug without gerrit trigger don't have this problem, so perhaps I've just configured this job incorrectly. The other gerrit plugin doesn't have this issue, either.
