Process.destroy is not working

Question

Im trying to kill a process from my JAVA code:

    File file = new File("c://test//test.jar");
    String folderToFile = file.getAbsolutePath();
    String filePath = folderToFile.substring(0,folderToFile.lastIndexOf(File.separator));
    String[] cmd = String.format("cmd /c java -jar %s", file.getName()).split(" ");
    Process pSimulator = (new ProcessBuilder(cmd))
            .directory(new File(filePath))
            .redirectErrorStream(true)
            .start();

    Thread.sleep(300);
    pSimulator.destroy();

I don't know why but the process that i'm trying to kill remains open... the "test.jar" that i'm running here is just a rendom jar that i've picked on the web...

any ideas?

Try using `pSimulator.waitFor();` before the `pSimulator.destroy();` — Gabriel Ilharco, Jan 14 '16 at 12:21

Looks like it is a bug in Java's Process.destroy() implementation on Windows. Refer this.

You can try to use Apache Commons Exec.

Does ```java -jar %s``` work instead of ```cmd /c java -jar %s```? – Jan 14 '16 at 13:15
