Stuck at "Building: 0% [0/1000]" in "Task - Java Build Status"

I wrote a Maven plugin to generate .class files and a .jar from OpenOffice .idl files.
When i open the workspace which uses said plugin the project compiles fine and auto completion works. But when i edit one of these .idl files autocompletion stops working and i'm getting stuck at "Building: 0% [0/1000]" in "Task - Java Build Status". The goal of my Maven plugin will still finish tho, so the issue seems to occur after my plugin finishes execution.
My Maven plugin uses the "META-INF/m2e/lifecycle-mapping-metadata.xml" file to make the plugin compatible with eclipse.
I also made sure that there's no compilation if nothing actually changed. I can run mvn install as often as i want and it won't change the modification dates of any of my generated files.

It would be nice if someone could show me how to debug the task "Java Build Status" so i can figure out what's wrong.

I'll try to somehow create 2 sample projects to reproduce if there is no way to debug it myself.

Environment

• Operating System: openSUSE Leap 42.2
• JDK version: 11.0.8, 2020-07-14
• Visual Studio Code version: 1.50.0, 2020-10-07
• Java extension version: 0.72.0, [2020-12-02]

Comienza reproduciendo el “Java Build Status” atascado con un workspace que utilice el plugin de Maven indicado y su archivo META-INF/m2e/lifecycle-mapping-metadata.xml. Compara el comportamiento antes y después de editar un archivo .idl de OpenOffice y utiliza la ruta de depuración solicitada para identificar por qué se detiene el autocompletado; se considera completado cuando el estado de compilación finaliza y el autocompletado sigue disponible después de que se ejecute el plugin.
