Java Language Process ch.vorburger.exec
Example
Launching external processes from Java using the raw java.lang.ProcessBuilder API directly can be a little cumbersome. The Apache Commons Exec library makes it a little easier. The ch.vorburger.exec library further extends upon Commons Exec to make it truly convenient:
ManagedProcess proc = new ManagedProcessBuilder("path-to-your-executable-binary")
.addArgument("arg1")
.addArgument("arg2")
.setWorkingDirectory(new File("/tmp"))
.setDestroyOnShutdown(true)
.setConsoleBufferMaxLines(7000)
.build();
proc.start();
int status = proc.waitForExit();
int status = proc.waitForExitMaxMsOrDestroy(3000);
String output = proc.getConsole();
proc.startAndWaitForConsoleMessageMaxMs("started!", 7000);
// use service offered by external process...
proc.destroy();
