Re: [m2e-dev] JDTCompilationParticipant

[Laurent RUAUD <laurent.ruaud@xxxxxxxxx>]

I have it used in GenericBuildParticipant:
  private boolean getRequireFullBuild(IMavenProjectFacade
projectFacade) throws CoreException {
    if(projectFacade.getResolverConfiguration().isSkipCompiler()) {
      // see MNGECLIPSE-823
      return projectFacade.getProject().getSessionProperty(IMavenConstants.FULL_MAVEN_BUILD)
!= null;
    }
    return false;
  }

While JDTCompilationParticipant calls:
  public void requestFullMavenBuild(IProject project) throws CoreException {
    project.setSessionProperty(IMavenConstants.FULL_MAVEN_BUILD, Boolean.TRUE);
  }

Removing JDTCompilationParticipant solves my looping builds; though it
does not mean it is the cause of my issue.
But it certainly contributes to it.

Regards.
