【问题描述】：

我编译了自己的 JDK，它位于 /home /fashion/desktop/openjdk ，并且我的 vscode 用户 settings.json 的内容是

{
    "editor.suggestSelection": "first",
    "vsintellicode.modify.editor.suggestSelection": "automaticallyOverrodeDefaultValue",
    //set project jdk
    "java.configuration.runtimes": [
        {
          "name": "JavaSE-15",
          "path": "/home/fashion/Desktop/openjdk/build/linux-x86_64-server-slowdebug/images/jdk",
          "sources": "/home/fashion/Desktop/openjdk/build/linux-x86_64-server-slowdebug/support/src.zip",
          // "sources": "/home/fashion/Desktop/src!/",
          "default": true,
        },
        {
            "name" :"JavaSE-14",
            "path" :"/usr/lib/jvm/java-14-openjdk-amd64",
        },
      ],
      //set editor jre
      "java.home" :"/usr/lib/jvm/java-14-openjdk-amd64",
      "java.trace.server": "verbose"
}

按照这个配置，我只能单步到JDK源码。（Java Source Code Not C/Cpp ,For example I Want to Step into System.out.prinf("HelloWorld"); ) 但是我不能添加任何cmets，也就是不能编辑JDK的源代码。

我该如何解决这个问题？谢谢

要调试 JDK 源代码，您应该安装扩展 C/C++。另外需要配置C++环境，请参考Using C++ on Linux in VS Code

在VS Code中打开JDK文件夹，按Ctrl+F5进入调试，选择环境C++(GDB/LLDB)，然后在launch.json中设置

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "compile java file",
            "type": "cppdbg",
            "request": "launch",
            "program": "/.../jdk/bin/javac",
            "args": ["Main.java"],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "lldb"
        },
        {
            "name": "run java project",
            "type": "cppdbg",
            "request": "launch",
            "program": "/..../jdk/bin/java",
            "args": ["Main"],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "lldb"
        }
    ]
}

试一试。
