Run Windows Command in Jenkins Plugin

[micha...@gmail.com]

Hi,

I would like to run a Windows command inside my Jenkins Plugin.

How can I achieve that?

The following code is not working:

@Override
public void perform(Run<?,?> build, FilePath workspace, Launcher launcher, TaskListener listener) {

try {
Launcher.ProcStarter procStarter=launcher.launch().pwd(workspace).cmdAsSingleString("dir " + workspace + " &&  attrib -R /S");
procStarter= procStarter.stdout(listener);
procStarter.join();
 } catch (IOException e) {
            e.printStackTrace();
            listener.getLogger().println("IOException !");
        } catch (InterruptedException e) {
            e.printStackTrace();
            listener.getLogger().println("InterruptedException!");
        }

}

I get the following error when I run a Job that uses this plugin:

java.io.IOException: Cannot run program "dir" (in directory "C:\LocalJenkins\plu
gins\michaelPlugin\work\jobs\buildTest\workspace"): CreateProcess error=2, The s

What should be the correct code to run some Windows commands?

Many thanks

I think you need to prepend cmd.exe to the dir command so something like cmd.exe /C dir

BTW, it's not a Jenkins specific question. More like a general Java one. So googling should give many answers.

Cheers
