Java Plugin 4.0 and Sonar 5.6

[qjafc...@gmail.com]

Hi,

i've just update my Sonar 5.6 with the latest Java plugin 4.0
My maven command (mvn sonar:sonar) uses version 3.0.2 of org.sonarsource.scanner.maven:sonar-maven-plugin.

With the new Java plugin 4.0, my mvn command fails :
[ERROR] Failed to execute goal org.sonarsource.scanner.maven:sonar-maven-plugin:3.0.2:sonar (default-cli) on project : Execution default-cli of goal org.sonarsource.scanner.maven:sonar-maven-plugin:3.0.2:sonar failed: An API incompatibility was encountered while executing org.sonarsource.scanner.maven:sonar-maven-plugin:3.0.2:sonar: java.lang.NoSuchMethodError: org.sonar.plugins.java.api.JavaResourceLocator.findResourceByClassName(Ljava/lang/String;)Lorg/sonar/api/resources/Resource;

With the previous version of Java plugin, my maven command success.

Best Regards,
qj

Hello qj,

Do you have version 3.3 of the Findbugs plugin installed on your SonarQube (SQ)?

If you don't have the findbugs plugin, I would be interested by the list of plugin you currently have installed in your SQ instance.

The Java Analyzer 4.0 introduced slight changes in API in order to stay aligned with API from SQ 5.6. Unfortunately, it also had as side effect to introduce potentially breaking changes for plugins relying on the Java Analyzer. 

However, as far as we know, only the findbugs plugin is affected. Note that version 3.4 of the Findbugs plugin, currently under request for feedback period (see this thread), should get back compatibility.

Okay, so you have 3 options:

• Delay the update to version 4.0 of the Java Analyzer, waiting for Findbugs next release fixing compatibility
  
• Remove the findbugs plugin from your plugins
• Try the release candidate of version Findbugs 3.4 (and provide feedback if compatibility is restored in the related topic, which would be really appreciated).

I've installed the 3.4.2 version of Findbugs, and all it's ok now.

tx Michael for your help.

Michael,

I was having the same problem, tried updating findbugs to 3.4.2 and was still getting the same error. Ultimately, I also had to remove the Cobertura plugin and then life got good again.

Thanks a lot for the notification David!

I created the a Github issue on the Cobertura project to notify its maintainer of the compatibility issue: Github Issue #5
