Description

I have a Maven job that fails occasionally with the following message:

ERROR: Processing failed due to a bug in the code. Please report this to jenkinsci-users@googlegroups.com
java.lang.NullPointerException
	at hudson.maven.MavenBuild$ProxyImpl2.close(MavenBuild.java:560)
	at hudson.maven.Maven3Builder.end(Maven3Builder.java:220)

	at hudson.model.ResourceController.execute(ResourceController.java:88)
	at hudson.model.Executor.run(Executor.java:145)

The workaround is to re-trigger the job. I don't know the exact failure rate, but let's say 1 in 4 or 5.

Sorry, but aren't you talking about two different things? My understanding of Maven's parallel build feature is that it allows Maven to build some modules in a multi-module project concurrently if the dependency graph allows it (and if the plugins are thread safe). But we're using the concurrent builds feature of Jenkins to run many jobs/builds concurrently. Specifically, a build is triggered as soon as someone pushes a commit for review to our Gerrit server. With concurrent builds, the machine is obviously utilized better - the alternative is a build queue with a lot of pending builds.

You're right. I was confusing this with 'Build modules in parallel'. Sorry for the confusion
