Node info in Jenkins pipeline environment

[conso...@gmail.com]

I'm write a jenkins plugin to get some infos of jobs,  i want to get the node info which the job running on.  now i have the code by extend RunListener,  the code works fine in free style project, but in pipeline, the EnvVars not contains NODE_NAME,  so it not works.

@Override

public void onCompleted(Run<?, ?> run, TaskListener listener) { 

  Node node = run.getExecutor().getOwner().getNode();

  String nodeName = node.getNodeName();

  EnvVars environment = run.getEnvironment(listener);

  if (nodeName.equals("") && environment.containsKey("NODE_NAME")) {

      nodeName = environment.get("NODE_NAME");

  }

}

But in the code workflow-durable-task-step-plugin ,  the NODE_NAME is put in the EnvVars. I don't know why this happened and is there any way  to get node info.

In my plugin I’m simply using build.getExecutor().getOwner().getName(). Note that getOwner() might return null.

In pipeline, the information is added to ENV_VARS only for the time that the pipeline really is using an executor on a node. So you will not be able to collect this information in the onCompleted method of a RunListener. Also consider that a pipeline can run on multiple nodes.

You might consider implementing an ExecutorListener.

Right, the problem statement does not even make sense. What you _can_
collect is a possibly empty set of nodes a build used.

You can use `RunListener`, just get the `FlowNode` graph and look for
those nodes with a `WorkspaceAction` attached.
