SonarQube Eclipse plugin throws error on local analysis

Question

We are running SonarQube 3.7. I'm using the SonarQube plugin for Eclipse, version 3.2.0.20130627-1142, on Eclipse 3.7.2. I have associated my projects with the SonarQube projects and am able to view issues from the server side great. However, if I switch to Local analysis, I get the following error, after CheckStyle, PMD, etc have run:

Everything runs fine on the server. Any ideas?

Answer 1

I also encountered a "Unable to execute Sonar... Fail to download... Response code: 500" with my installation (Sonar v3.7.2, Eclipse plugin v3.2 and Eclipse 4.3) when running a local analysis.

I noticed one of my classes in my stacktrace Caused by line (where yours shows "ClockEventHelperIT"). The class doesn't exist in my server side repository (it's new) and is also located in the default Java package. It was a throwaway class so I decided to remove it and re-run the analysis. That solved it for me.
