Here’s an example of what I think you want to do:
ProcessBuilder pb = new ProcessBuilder(args);
pb.redirectErrorStream(true);
Process proc = pb.start();
InputStream is = proc.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line;
int exit = -1;
while ((line = br.readLine()) != null) {
// Outputs your process execution
System.out.println(line);
try {
exit = proc.exitValue();
if (exit == 0) {
// Process finished
}
} catch (IllegalThreadStateException t) {
// The process has not yet finished.
// Should we stop it?
if (processMustStop())
// processMustStop can return true
// after time out, for example.
proc.destroy();
}
}
You can improve it 🙂 I don’t have a real environment to test it now, but you can find some more information here.
