Question

基本上，我有完全相同的问题链接在这里： How can i send data to the logger from FileCallable back to master in a Jenkins plugin?

但我无法让它发挥作用。我编写了自己的自定义Jenkins插件，它必须在奴隶上运行。但是，我想记录主jenkins（或者至少是构建日志）。这是我的代码（为简单起见，有点简单）：

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中给我以下输出：（这是主记录）

所以基本上，记录器（它是一个PrintStream）是不可序列化的。我如何让我的奴隶登录主詹金斯？

Answer 1

侦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listener.getLogger().println();函数中使用call()。

Answer 2

这应该打印到构建日志：

listener.getLogger().println(your_text);

Jenkins自定义插件可以在奴隶日志上掌握吗？
