Pax Exam выполнить команду против Карафа

В Karaf 4.x команды изменились, поэтому вам нужно изменить их соответствующим образом. Полный образец можно найти здесь

Подводя итог, вам понадобится SessionFactory в вашем тесте, см. ниже:

@Inject
protected SessionFactory sessionFactory;

и оттуда создайте объект сеанса:

@Before
public void setUpITestBase() throws Exception {
    session = sessionFactory.create(System.in, printStream, errStream);
}

Я сделал это в предыдущей части теста, чтобы убедиться, что сеанс всегда создается новым.

Следующее является важной частью для выполнения команд:

    String response;
    FutureTask<String> commandFuture = new FutureTask<String>(new Callable<String>() {
        public String call() {
            try {
                System.err.println(command);
                session.execute(command);
            } catch (Exception e) {
                e.printStackTrace(System.err);
            }
            printStream.flush();
            errStream.flush();
            return byteArrayOutputStream.toString();
        }
    });

    try {
        executor.submit(commandFuture);
        response = commandFuture.get(10000L, TimeUnit.MILLISECONDS);
    } catch (Exception e) {
        e.printStackTrace(System.err);
        response = "SHELL COMMAND TIMED OUT: ";
    }

Ахим Нирбек решил эту головную боль для меня, поэтому для справки посмотрите его ответ. Если кому-то просто нужен пик кода, который работал у меня.
