During the incremental build that follows a change to the POM, the m2e build participants suffer from a stale MavenProject instance being passed to them which does not reflect the POM change which has just been made. One user-visible effect of this is are error markers which basically reflect the previous POM contents but not the current.

At least one piece of the error is the following code from MavenBuilder:

    if(projectFacade.isStale()) {
      MavenUpdateRequest updateRequest = new MavenUpdateRequest(project, mavenConfiguration.isOffline() /*offline*/,
          false /*updateSnapshots*/);
      projectManager.refresh(updateRequest, monitor);
      IMavenProjectFacade facade = projectManager.create(project, monitor);
      if(facade == null) {
        // error marker should have been created
        return null;
      }
    }

While this code properly detects the isStale() state, the newly re-recreated facade object is not used, i.e. doesn't replace the stale projectFacade instance.
