【问题标题】：IntelliJ debug breakpoints not working for Tomcat Run ConfigurationIntelliJ 调试断点不适用于 Tomcat 运行配置

上下文

我有一个带有端点的小应用程序，它调用了一些转换器库。我的Run Configuration 是Tomcat 类型，并部署了一个爆炸战争，这是我的应用程序。

在该应用程序的pom.xml 的<dependencies> 中，我有一个需要调试的外部库。显然，该库是在我的应用程序中调用的。

当我在Debug 模式下启动Tomcat Run Configuration 时，日志表明代理似乎已正确设置并且工件已成功部署（以下是我认为相关的日志子集）：

然后，我可以看到由于白色复选标记，我的断点已注册：

但是，这只是模块src/main/java 目录中的代码的情况。我正在尝试调试的库（位于 External Libraries 中）不会注册断点：

我添加了几行日志记录，并修改了该库的 pom.xml 中的版本，并在库和我的应用程序中运行了 mvn clean install，以确保我指向了正确的代码版本。

诊断

现在奇怪的部分来了。当我运行调用我的应用程序端点的测试时，我看到以下日志：

com.my.app.ExecutionServiceException: java.lang.NullPointerException: TheConverter.java, notWithinYearBoundaries line 1110
    at com.my.app.handleTransaction(MyAppEndpointHandler.java:143)

这向我证明，我在日志记录 (L1109) 上有断点的库代码确实正在运行（我在 Tomcat 日志中看到了实际日志）。

此外，当我点击MyAppEndpointHandler.java:143 时，IntelliJ 确实打开了我设置断点的类，该断点标记为已注册（是的，L61 与L143 在同一函数内）。

问题

当代码到达L61 上的注册断点时，IntelliJ 甚至不会中断正在运行的应用程序以向我显示调试窗口。
IntelliJ 拒绝在外部库中注册我的断点。

我尝试过的事情

这很令人不安，我尝试了很多不同的东西（我在that other SO question 看到的一堆东西，等等）：

clean & rebuild
关闭所有项目，并删除target、.idea/和*.iml
更新我的 IntelliJ 版本（从 2020.3 到 2020.3.2）
尝试另一个版本的 Tomcat
Invalidate Caches & Restart
还有更多...

值得一提的是，我团队中的另外两个开发人员报告说，在他们的机器上，他们没有遇到我的问题。而且我们似乎必须使用相同的 IntelliJ 配置和设置。

设置和运行配置

这里是Tomcat Run Configuration：

这是我的Debugger 设置：

IntelliJ 调试控制台输出

这是控制台日志的部分版本：

断点属性

【问题讨论】：

Minimal, Complete, and Verifiable example 能够重现和调查这个问题会很棒。库是在启用调试信息的情况下构建的吗？您还可以为 Java 调试器启用日志记录，以查看断点未获得复选标记的原因：intellij-support.jetbrains.com/hc/en-us/articles/207241125。
@CrazyCoder 1) 我如何知道库是在启用调试信息的情况下构建的？ 2) 我在 IntelliJ 的日志记录 output.txt 上看到了 [JDI: EventSet: SUSPEND_NONE]。会是这样吗？ 3）您可能想要更新链接的博客文章：我不得不使用这个技巧来实际重定向输出stackoverflow.com/a/1420981/9768291
@CrazyCoder 我用调试控制台日志的缩短版本更新了 OP。
你能显示断点属性吗？为它设置了什么暂停政策？
@CrazyCoder 用截图更新了 OP（在日志之后）

【解决方案1】：

原来是有误会。我以为 Test 类是在对 localhost Tomcat 实例进行网络调用，而实际上它直接调用了源代码。

这就是为什么当我在调试模式下启动 Tomcat 运行配置时，我会在我的源代码中获得一个已注册的断点，但它永远不会暂停应用程序，尽管我看到了日志。

由于应用程序被配置为在target 的文件中输出日志，我认为这些日志来自 Tomcat。

从以 Debug 模式启动的 Test 类进入，将我带到应用程序代码，最终也到达库代码。这也是为什么我在调试模式下启动 Tomcat 运行配置后正常运行测试类时看到来自库的日志，但没有看到注册断点的原因。

呃。这是一段既尴尬又耗时的旅程。
