I wrote a quick amper project for some data analysis the other day, and noticed that breakpoints didn't work on jvm when running debug in fleet. Is this expected?

Hi Landry, thanks for the report. This is not expected, but I couldn't reproduce your issue 🤔 Would you mind sharing more information? If you can share your sample project as a whole that's great, but otherwise at least a bit more details about the kind of project and your setup. For instance is it a pure JVM project or a multiplatform one? Which version of Fleet and Gradle did you run?

[Landry Norris]

It's a pure jvm app, so my module.yaml only contains product: jvm/app, and it's a small project, so only a main function. I checked that I can't reproduce with just a simple hello, world in main, so I'll have to play around with it and see if I can find a minimal reproducer. I'm on the latest Fleet.

Interestingly, when I copied my code, then trimmed it to just a hello, world, then pasted it back, breakpoints work now. They didn't work on the same code before.

Oh, thanks for the additional info. Well, good to hear that this is resolved. Though it's still a bit puzzling that breakpoints didn't work consistently for you 🤔

I spent a fair bit of time trying to figure it out yesterday, but really just wanted to check if I was wasting my time on a known limitation. It's good to know that breakpoints should work. The only thing I could think of is that I got an error in Fleet at some point that the IntelliJ engine was out of sync and had to restart the IDE. That may have messed with something.
