How do I properly set the property ProjectName for a JNI program?

[Lyxien]

My project is using C++ to call JAVA code via JNI and there is no static main method in the code. When using the debugging watch function, the program reminds me that I need to specify the projectName in launch.json, but I don't know where this ProjectName comes from?

Environment

• Operating System: Ubuntu
• JDK version: openjdk version "17.0.12"

this is my launch.json:

            "type": "java",
            "name": "mydebug",
            "request": "attach",
            "hostName": "localhost",
            "port": 8002

You can use Java Projects view to find out what Java project your source file is located.
