我正在尝试运行PAX考试，该考试启动了Karaf实例版本4.0.2，然后部署了一些功能。一切都运作到目前为止。
但是，我还想运行一些命令来检查捆绑包是否已经安装，即运行＆＃34;捆绑：列表＆＃34;命令。
我在这里添加了executeCommand和getOsgiService方法： https://github.com/christian-posta/rider-auto-osgi/blob/master/itests/src/test/java/org/jboss/fuse/example/support/FuseTestSupport.java#L80
但是我得到了RuntimeException：
root这是导致异常的代码。

使用Karaf 4.x命令确实发生了变化，因此您需要相应地更改它。 可以找到完整的样本here
作为快速总结，您需要在测试中使用SessionFactory，请参阅下文：
@Inject
protected SessionFactory sessionFactory;
并从那里创建一个会话对象：
@Before
public void setUpITestBase() throws Exception {
session = sessionFactory.create(System.in, printStream, errStream);
}
我在测试的前一部分做了这个，以确保会话总是创建新的。
以下是执行命令的关键部分：
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: ";
}

Achim Nierbeck为我解决了这个问题，以便参考他的答案。如果有人只想在代码上找到适合我的高峰。
