How to check Jenkins build status

I'm actually executing my own Jenkins plugin and I have a class that extends from RunListener<Run>

, with the following method onCompleted()

:

@Override
public void onCompleted(Run build, TaskListener listener) {
    int number = build.number;
    EnvVars env;
    String name = "";
    try {
        env = build.getEnvironment(listener);
        name = env.get("JOB_NAME") + "-" + env.get("BUILD_NUMBER");
    } catch (IOException | InterruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    GraphicAction act = new GraphicAction(name);
    build.getActions().add((Action) act);
}

      

        
        
        
      

    

Is it possible to execute the last two lines only if the build is successful?

Thank!
