I installed this plugin AppMap, and after I uninstalled I was unable to run any junit test cases or our java app.
When I run my junit test case, I get options to Test with AppMap. I choose one of them and I get this error
command 'appmap.getAppmapDir' not found
I uninstalled the extension and also did what some answers recommended, tried to find the extension folder in ~/.vscode/extensions folder. Unable to find a folder with appmap.
After doing a search I realized that launch.json and settings.json had enteries for Test with AppMap and Run with AppMap. Removed those configs and things started to work again.
This has been documented in the extension documentation too here, thanks @petecheslock.
