Examples of org.zeroturnaround.exec.ProcessExecutor.execute()

org.zeroturnaround.exec.ProcessExecutor.execute()
Executes the sub process. This method waits until the process exits, a timeout occurs or the caller thread gets interrupted. In the latter cases the process gets destroyed as well. @return exit code of the finished process. @throws IOException an error occurred when process was started or stopped. @throws InterruptedException this thread was interrupted. @throws TimeoutException timeout set by {@link #timeout(long,TimeUnit)} was reached. @throws InvalidExitValueException if invalid exit value was returned (@see {@link #exitValues(Integer)}).
