java - Jenkins 可以在 slave 日志上自定义插件到 master 吗？

Question

基本上，我有与此处链接完全相同的问题: How can i send data to the logger from FileCallable back to master in a Jenkins plugin?

但我无法让它工作。我已经编写了我自己的自定义 Jenkins 插件，它必须在从服务器上运行。但是，我想记录到 master jenkins(或至少到构建日志)。这是我的代码(为简单起见删减了一点):

public class SanityTestResultsToJUnitXMLBuilder extends Builder implements Serializable  {

  // Some initialization code

  @Override
  public boolean perform(AbstractBuild build, Launcher launcher, BuildListener listener) {   

    // Define what should be run on the slave for this build
    SlaveChannel slaveChannel = new SlaveChannel(sourceDirectories, destinationDirectory, listener.getLogger());
    if (launcher.getChannel().call(slaveChannel).equals("NOK")){
        return false;
    }
    return true;
  }

  private static final class SlaveChannel implements Callable<String, IOException>
  {
    // Again, some initialization code

    public SlaveChannel(String sourceDirectories, String destinationDirectory, PrintStream logger){
        this.sourceDirectories = sourceDirectories;
        this.destinationDirectory = destinationDirectory;
        this.logger = logger;           
    }

    public String call() throws UnknownHostException
    {
        logger.println("Running the SanityTestResultsToJUnitXML plugin on host: " + InetAddress.getLocalHost().getHostName());
        if (startProcess()){
            return "OK";
        } else {
            return "NOK";
        }
    }

    private boolean startProcess(){
      // The code that needs to run client side
    }
  }

现在它在 Jenkins 中为我提供了以下输出: (这是主日志记录)

所以基本上，记录器(它是一个 PrintStream)是不可序列化的。我如何仍然让我的奴隶登录到主要的 Jenkins ？

Answer 1

监听器对象是可序列化的。因此，您可以将此对象传递给可调用类构造函数，并在 call() 函数中使用 listener.getLogger().println();。
