sonar 5.2 NullPointerException

Question

My environment is the following:

http://localhost:9000/sonar/api/server/version :: 5.2
java,sonar-java-plugin-3.7.jar|07dba2b9cad37584d82522414b2dccd0
scmgit,sonar-scm-git-plugin-1.0.jar|e1d9d8e1d3524f9f0f69017e6dbead02
scmsvn,sonar-scm-svn-plugin-1.2.jar|188d526ad86ec7f2dc7de694bf5f1851

printenv | grep MAVEN<BR>
MAVEN_OPTS=-Xmx1024m -XX:MaxPermSize=512m

I launch the command:

mvn sonar:sonar -Dsonar.verbose=true

and it fails as reported here below.

If I insert the file MyFileName.java (ref. backtrace) in the SonarQube Global Source File Exclusions, then the process goes ahead, up to a next file (likely to a next file that needs to be traced because it's affected by some issue) and it fails again with the same symptoms.

There's no specific trace in the sonar.log file.

Same results with:

mvn org.codehaus.mojo:sonar-maven-plugin:2.6:sonar -Dsonar.verbose=true

The main project I'm trying to analyse is very wide and the "module" that is failing is the 103rd one; this is only to say that there are several modules already processed in the previous stages without any sonar failures.

Any suggestions on how I could investigate this issue?

Would you be able to test Sonarqube 5.2 with sonar-java-plugin-3.6 to see if this issue is due to version 3.7 of the java plugin? — Massimo - SonarSource Team, Nov 04 '15 at 15:00
Thanks for the feedback but we already performed exactly the tentative you're suggesting. Also with Sonar Java Plugin 3.6 the output is the same: failure with same symptoms. — railnet, Nov 04 '15 at 16:02
Would you be able to share the source code of the file where the failure is happening ? — benzonico, Nov 05 '15 at 08:53
Hi, I installed again the system from scratch and it solved. — railnet, Nov 05 '15 at 21:59

I also had this issue and found that upgrading (from 5.2) to SonarQube 5.3 resolved it. This suggests that the issue is related to a bug with 5.2 however I have not been able to track down the specific fix. I'll update this answer with a link to the Jira if I find it
