Simple Java subprocess management

## What? ## A simple library for executing a subprocess from within a Java program. java-exec provides: * Simple capture of output as a string * Handling output as streaming lines * Piping the output to another stream * Error capture * Subprocess timeout ## Examples ## ### Simple output capture ### CommandExecutor executor = new CommandExecutor(Arrays.asList("ls")); String dirContents = executor.run(); System.out.println(dirContents); ### Process output as lines ### CommandExecutor executor = new CommandExecutor(Arrays.asList("ls")); executor.run(new LineHandler() { public void handleLine(String line) { System.out.println(line); } }); ### Stream output ### CommandExecutor executor = new CommandExecutor(Arrays.asList("ls")); executor.run(System.out); ### Subprocess timeout ### long cmdTimeout = 3000; // 3 seconds CommandExecutor executor = new CommandExecutor(Arrays.asList("sleep", "5"), cmdTimeout); try { executor.run(); } catch (CommandExecutorException e) { System.out.println("Caught exception: " + e.getMessage()); // handle timeout if you like, however // CommandExecutorException extends RuntimeException, so // you can also let it kill your program if the // scenario cannot reasonably be handled } ### Copyright Copyright 2010 ThoughtWorks, Inc.
