Capturing stdout when calling Runtime.exec

Question

When experiencing networking problems on client machines, I\'d like to be able to run a few command lines and email the results of them to myself.

I\'ve found Runtim

Use Plexus Utils, it is used by Maven to execut all external processes.

Commandline commandLine = new Commandline();
commandLine.setExecutable(executable.getAbsolutePath());

Collection args = getArguments();

for (String arg : args) {
    Arg _arg = commandLine.createArg();
    _arg.setValue(arg);
}

WriterStreamConsumer systemOut = new WriterStreamConsumer(console);
WriterStreamConsumer systemErr = new WriterStreamConsumer(console);

returnCode = CommandLineUtils.executeCommandLine(commandLine, systemOut, systemErr, 10);
if (returnCode != 0) {
    // bad
} else {
    // good
}
