Conditional breakpoint evalutation fails -- where do I look for the problem?

[chauser]

Describe the question you have.
When simulating one of my 2025 java robot projects with a conditional breakpoint set, a popup appears when the breakpoint location is reached with the message:

Breakpoint condition '(this.m_positionCorrection > 0.01)' error: Cannot evaluate, please specify projectName in launch.json.

Conditional breakpoints work in other 2025 java projects. I can't figure out what's different about the one where they don't work. The pointer to launch.json seems to be a red herring as projectName does not appear to be a valid field in the configurations listed there, according to Intellisense. Further, the contents of launch.json in this project are the same as in the projects where it works:

{

  "configurations": [

    {
      "type": "wpilib",
      "name": "WPILib Desktop Debug",
      "request": "launch",
      "desktop": true,
    },
    {
      "type": "wpilib",
      "name": "WPILib roboRIO Debug",
      "request": "launch",
      "desktop": false,
    }
  ]
}

This is on linux, Ubuntu 22.04. I haven't tried it for this project on Windows. I'll do that now and update the question with what I find.

Where do I look next? Thanks.

You don't happen to have a space in the project name, right? Otherwise, thats not really anything we've seen.

You're right that error isn't great. Due to the native library requirements, we actually inject a custom launch.json into VS Code when you run either that command or the sim command.

If you run the WPILib: Show Log Folder command, that will open up the logs, which I think has the launch.json contents we inject. You theoretically can replace the one in the project with that and it should work. Hasn't been tested in a while though. But you can also compare that to one of the projects that work.

Here's the content of the log file. I added spaces between the lines for readability. The first pair, referencing robot-2025-practice, corresponds to a project where conditional breakpoints work. The second pair, referencing robot-2025, is for the project where they don't work. I'm not spotting any fundamental difference. However, on my windows machine the breakpoints work in the robot-2025 project so I'll move on to doing the work I need to do there and come back to this at a less critical time. Thanks, Thad, for the help.
