Closing all open command prompt leads to error in forked process in testNG

Question

I am using testNG for mobile automation and I want to close multiple command prompts(appium servers) which i launched. For this, I am using the below code

@AfterSuite
    public void closeCommandPrompts() throws IOException, InterruptedException{
    System.out.println("After suite");
    Thread.sleep(8000);
    Runtime.getRuntime().exec("taskkill /F /IM node.exe");
    System.out.println("closed node.exe");
    Runtime.getRuntime().exec("taskkill /F /IM cmd.exe");

The last line if I commnet it out works fine, however if they are not commented it gives an error in the forked process.

I guess testNG is internally using command prompt which i am trying to close when iam using taskkilll in @aftersuite.

Please help me in getting some work around.

You can use following code :

     CommandLine command = new CommandLine("cmd");
      command.addArgument("/c");
      command.addArgument("taskkill");
      command.addArgument("/F");
      command.addArgument("/IM");
      command.addArgument("node.exe");

      DefaultExecuteResultHandler resultHandler = new DefaultExecuteResultHandler();
      DefaultExecutor executor = new DefaultExecutor();
      executor.setExitValue(1);
      try {
            executor.execute(command, resultHandler);
            System.out.println("Stopped appium node ! ");
      } catch (IOException e) {
            System.out.println("FAIL => Unable to stop appium server "+e.getMessage());
            e.printStackTrace();
      }
