Romi (Java) example code doesn't build

[mjhealy]

Describe the bug After generating a new instance of the Romi (Java) example project, I attempted a build, which fails out of the box.

To Reproduce Steps to reproduce the behavior:

1. Generate a new "RomiReference" example instance, targeting Java.
2. Kick off a build.

Expected behavior Code should build without issues, since it is an unmodified example.

Actual behavior Errors reported:

Build file 'C:\Users\quasi\Desktop\quasics-frc-sw-2015-pre-light-fix.git\trunk\Experimental\2023\Romi-Beta\build.gradle' line: 38

It looks like there's an extra "}" on line 38 of the generated build.gradle file. Removing that (or commenting it out) appears to resolve the issue.

However, I see a similar failure when trying to start the simulator in order to work with the Romi, so I'm guessing that there's another issue that needs to be fixed.

Error when trying to run the simulator:

What is the error that occurs when trying to start the simulator?

[rzblue]

Try running "Java: Clean Java Language Server Workspace" in the command palette, that should fix it.

That does seem to resolve the issue. (At the least, the simulator starts running; I don't currently have the Romi powered up/connected to verify full functionality.)
