在Eclipse中使用Maven SureFire插件进行调试

Question

当我在Eclipse中调试时，我得到了以下错误。

我已经调试了配置，其中goal = -Dmaven.surefire.debug干净安装，远程java应用程序配置，其中host=localhost和port=5005。这可以让我调试junit测试用例并停止工作。

Answer 1

当端口5005已在使用中时，通常会发生这种情况。假设您使用的是windows，您可以使用下面的命令来查找监听端口5005的进程的PID，您将获得所有监听的PID和端口的列表，并且您必须检查5005

netstat -aon | find /i "listening"

在linux上这很简单。

lsof -i:5005

一旦你有了PID，你就可以在windows上使用下面的命令来杀死它

taskkill /F /PID {PID}

在linux/mac上

kill -9 {PID}

然后尝试调试maven测试，它应该可以工作。
