luntbuild + maven + findbugs = OutOfMemoryException
- by Johannes
Hi,
I've been trying to get Luntbuild to generate and publish a project site for our project including a Findbugs report. All other reports (Cobertura, Surefire, JavaDoc, Dashboard) work fine, but Findbugs bails out with an OutOfMemoryException. Excluding findbugs from report generation fixes the build --- although obviously without a Findbugs report.
The funny thing is that I first encountered this problem locally and solved it by setting MAVEN_OPTS=-Xmx512m. This does not seem to be enough in Luntbuild, however: setting that exact same option as an environment variable of my builder doesn't make a difference.
I've found a couple of posts on the 'net stating you should also add -XX:MaxPermSize=512m to MAVEN_OPTS and/or pass -Dmaven.findbugs.jvmargs=-Xmx512m to mvn.bat. None of these (or their combination) seem to help though so any hints would be greatly appreciated!
Cheers,
Johannes
Relevant information:
Luntbuild is 1.5.6, Maven is 2.1.0, findbugs-maven-plugin is 2.0.1.
This is the Findbugs section of the relevant pom.xml:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>findbugs-maven-plugin</artifactId>
<version>2.0.1</version>
</plugin>

Maven2 builder failed: build success condition not met!
Note that apparently maven only uses 70MB... but that probably doesn't mean anything since the Findbugs plugin forks its own process.
