Maven 在下面一行挂了一段时间
Concurrency config is parallel='none', perCoreThreadCount=true, threadCount=2, useUnlimitedThreads=false
我不知道如何为 maven 开启更多调试。
我看到 Log4J 输出的第一行会在 1.5 分钟后出现，原因不明。
我想调查一下为什么会发生这种挂起，有没有人遇到过类似的问题？如何获得更多关于正在发生的事情的调试输出？
非常感谢任何帮助。

【问题讨论】：
-
诊断这类错误真的很困难，因为它可能是你的一个测试造成了死锁（或类似的）。您可以做的是在挂起时进行线程转储，您将看到哪些线程正在等待。另一方面，Log4J 可以配置为异步记录......这可能是 1.5 分钟没有日志的原因（但您的测试确实在运行）
-
亲爱的奥古斯托。添加了 log4j 配置。您是否看到任何用于异步日志记录的配置。
-
您似乎没有使用 AsyncAppender。您是否尝试过获取线程转储？这将为您提供有关测试无响应原因的更多信息。
