Java 使用maven project的NetBeans在附加到另一个应用程序中的jvm时不会单步执行代码

java maven debugging netbeans

Java 使用maven project的NetBeans在附加到另一个应用程序中的jvm时不会单步执行代码,java,maven,debugging,netbeans,Java,Maven,Debugging,Netbeans,我第一次在Maven中使用NetBeans。在NetBeans中，一切都很好。可以构建、包安装等。可以调试和单步执行代码。当我试图通过附加到另一个链接JVM实例的应用程序而不是在NetBeans中调试代码时，问题就开始了我使用共享内存传输连接到一个进程，它成功了。当我从该进程调用带有断点的java方法时，它会中断。我可以检查变量，可以看出它停在了正确的位置，但它拒绝单步执行代码。NetBeans没有在它停止的那一行用绿色高亮显示，代码的单步执行导致NetBeans进入一些Java内部，弹出In

我第一次在Maven中使用NetBeans。在NetBeans中，一切都很好。可以构建、包安装等。可以调试和单步执行代码。当我试图通过附加到另一个链接JVM实例的应用程序而不是在NetBeans中调试代码时，问题就开始了

我使用共享内存传输连接到一个进程，它成功了。当我从该进程调用带有断点的java方法时，它会中断。我可以检查变量，可以看出它停在了正确的位置，但它拒绝单步执行代码。NetBeans没有在它停止的那一行用绿色高亮显示，代码的单步执行导致NetBeans进入一些Java内部，弹出Integer类、HashMap类等，并抱怨没有可用的源代码。不过，我可以在代码中设置另一个断点，然后单击“继续”。它会停在那里，但不会再前进

我的猜测是它与maven和类文件中不完整的调试信息有关。如果我重新配置我的项目以使用ant，那么一切都正常工作，但是回到maven会再次把它搞砸

NetBeans中的调试视图显示“隐藏的源代码调用”：

有人有什么想法吗？谢谢

我使用链接的jvm.dll启动应用程序，并使用以下选项：

-Xdebug-Xrunjdwp:transport=dt_shmem，address=myexecutable，server=y，suspend=n

以下是我的示例pom文件：

问题已解决。解决方法非常简单。事实证明，对于在NetBeans环境之外创建的Maven项目，不仅要打开父项目，还要打开项目中的所有模块。由于我的无知，我没有这样做。我只打开了父项目

在“打开项目”对话框中，实际上有一个复选框“打开所需的项目：”并且该复选框处于关闭状态。我选中该复选框后，我的父项将所有模块作为单独的项目打开，所有模块都运行得很好

因此，这个问题与Java类文件中不完整的调试信息无关。默认情况下，此复选框处于关闭状态只是NetBeans的一个特性
