I have a simple Command with one mandatory parameter:
@Parameters(index = "0", description = "manifest")
private File manifest;
When I call it from the command line without a parameter I get the expected message:
Missing required parameter: <manifest>
Usage ....
BUT: the return code for the call to java is 0, implying everything went fine.
Is there a way to have picocli return a non-zero code if a parameter (or option) is missing/incorrect?

Yes this is possible. The following program will exit with exit code 456 if the user provided invalid input:
@Command
class ExitCodeDemo implements Runnable
@Parameters(index = "0", description = "manifest")
private File manifest;
public void run()
// business logic here
public static void main(String... args)
CommandLine cmd = new CommandLine(new ExitCodeDemo());
cmd.parseWithHandlers(
new RunLast(),
CommandLine.defaultExceptionHandler().andExit(456),
args);
There are plans for adding better exit code support to picocli in version 4.0.
