Can not execute Findbugs: java.lang.OutOfMemoryError: Java heap space, while running mvn sonar:sonar -X
build, maven, out-of-memory, sonarqube
Solution
This is a well-known problem: Findbugs is really memory hungry, so I'm not surprised that with a 900MB project, you have to increase the JVM memory options quite a lot.
3 things you can do:
increase again the JVM memory options till it is OK
reduce the amount of activated Findbugs rules in your Sonar quality profile
refactor your project is smaller modules so that each module requires less memory to get analyzed by Findbugs
If I were you, I'd really go for at least option #3, because 900MB for a single project is really huge.
Problem
i am trying to do the code analysis in sonar 2.11, using maven 3. I am facing this error `java.lang.OutOfMemoryError: Java heap space`. i tried to increase the MAVEN_OPTS to `-Xmx1024m -Xms512m -XX:MaxPermSize=256m` but no use. The project is of large size of about 900MB. I am using the command `mvn sonar:sonar -X` in maven 3. But the build is failure. I am not running the tests or nor using any surefire plugin in my superPOM. So i am unable to find the cause of the problem. Please help me to figure out where the problem exixts. Thanks in advance...
