Java Question

API incompatibility with SonarQube 5.6 and Java Analyzer 4.0 with Findbugs 3.3 or Cobertura 1.6.3

The analyzes of my projects are failing with SonarQube

5.6
, after updating the Java Plugin from version
3.14
to
4.0
.

In my SonarQube instance, among other plugins, I currently have the Findbugs plugin (version
3.3
) and the Cobertura plugin (
1.6.3
) which require the Java plugin.

Looking at the log, I get the following message:

[ERROR] Failed to execute goal org.sonarsource.scanner.maven:sonar-maven-plugin:3.1-build231:sonar (default-cli)
on project MyProject: Execution default-cli of goal org.sonarsource.scanner.maven:sonar-maven-plugin:3.1-build231:sonar failed:

What should I do to get my analysis not failing?

Answer

Version 4.0 of the SonarQube Java Analyzer introduced changes in its API, in order to stay aligned with the new API of SonarQube 5.6 LTS (Long Term Support).

Unfortunately, these changes potentially broke compatibility with plugin directly relying on the Java Analyzer. If last released versions of PMD and Checkstyle plugins are not affected, version 3.3 of the Findbugs is unfortunately not compatible anymore, as well as version 1.6.3 of the Cobertura plugin.

In order to solve the issue with Findbugs, you have the following option:

  • Update to version >= 3.4 of the Findbugs plugin, which is currently in Request For Feedback period (see this thread), and should be released soon (confirmed with version 3.4.2).
  • Remove the Findbugs plugin or temporarily disable its rules.

For the Cobertura plugin, update to version >= 1.7 (requires LTS 5.6 and Java 8), which solve the issue. The update should be available using the SonarQube UI.
