Visual Studio Code projectName

Question

Using VS Code for Java debugging, there must be projectNamedefined in the launch.json file for using the watch-window while debugging.

How to determine and/or define the name of the Java project?

I always get the error message:

Failed to resolve classpath: The project '??' is not a valid java project.

Here my launch.json extract:

        "type": "java",
        "name": "Debug (Launch)-Application<foo>",
        "request": "launch",
        "cwd": "${workspaceFolder}",
        "console": "internalConsole",
        "stopOnEntry": false,
        "mainClass": "FooClass",
        "args": "",
        "projectName": "??",
        "windows": {
            "classPaths": [
                "%CLASSPATH%","C:\\JUnit\\junit-4.12.jar", "C:\\JUnit\\hamcrest-junit-2.0.0.0.jar", "."
            ]
         }

i was going crazy trying to figure out why the update i made to .project and pom.xml didn't change the project name in vs code...

1. edit projectDescription / name in .project

2. edit artifactId in pom.xml

3. here's what i did to get it to reload and show the updated project name:

Answer 2

The VSCode contains JAVA PROJECTS on the sidebar. I am using SSH plugin to connect to a machine where the project actually resides (VS Code runs locally) so the name of the java project is my name and some hash to it

After adding the hash "_c4503cca" to the projectName in launch.json, the watches in debug mode work fine.
