如何将数据从FileCallable发送到记录器，再通过Jenkins插件发送给主服务器? [英] How can i send data to the logger from FileCallable back to master in a Jenkins plugin?

问题描述

我正在使用此处中的以下示例:

I'm using the following example from here:

 void someMethod(FilePath file) {
     // make 'file' a fresh empty directory.
     file.act(new Freshen());
 }
 // if 'file' is on a different node, this FileCallable will
 // be transferred to that node and executed there.
 private static final class Freshen implements FileCallable<Void> {
     private static final long serialVersionUID = 1;
     @Override public Void invoke(File f, VirtualChannel channel) {
         // f and file represent the same thing
         f.deleteContents();
         f.mkdirs();
         return null;
     }
 }

Freshen类将被序列化并发送到从站以执行.我如何从Freshen类内部访问并记录主记录器上的记录器进度?

The Freshen class will be serialized and sent to a slave for execution. How can i get access and log progress to the logger on the master from inside my Freshen class?

推荐答案

我参加聚会有点晚了，但是我偶然发现了同一个问题，并通过将TaskListener传递给FileCallable来解决了这个问题:

I am a bit late to the party, but I just stumbled upon the same problem and solved it by passing the TaskListener to the FileCallable:

private static final class Freshen implements FileCallable<Void> {
    private static final long serialVersionUID = 1;

    private final TaskListener listener;

    public Freshen(TaskListener listener) {
        this.listener = listener;
    }

    @Override public Void invoke(File f, VirtualChannel channel) {
        RemoteOutputStream ros = new RemoteOutputStream(listener.getLogger());
        ros.write("hello there".getBytes(StandardCharsets.UTF_8));

        return null;
    }
}
