Gradle multi-module project breaks on reload, requires cleaning Java Language Server workspace every time

Description
I am working with a Java Gradle multi-module project in VS Code.
On the first load, the project fails with an error like:

The project was not built due to "xxx does not exist". Fix the problem, then try refreshing this project and building it since it may be inconsistent.

The suggested workaround is:

• Disable Gradle for Java extension
• Run "Java: Clean Java Language Server Workspace"
• Reload the project

This workaround does fix the problem, but only temporarily.

Problem
Every time I:

• reload the window, or
• close and reopen the project

I have to run "Java: Clean Java Language Server Workspace" again, otherwise the same error appears.

This makes working with the project very inconvenient.

Expected behavior
Once the project is cleaned and loaded successfully:

• It should stay in a consistent state
• Reloading or reopening the project should not require cleaning the Java Language Server workspace again

Actual behavior

• Project breaks again after reload
• Same error repeats
• Manual workspace cleaning is required every time

Environment

• VS Code
• Java multi-module Gradle project
• Java Language Server
• Gradle for Java extension enabled

Additional notes
This looks like a workspace cache or Gradle project import inconsistency issue.
It seems the Java Language Server does not correctly persist the resolved multi-module Gradle state across reloads.

Beginne damit, den Fehler in VS Code mit einem Java-Gradle-Projekt mit mehreren Modulen zu reproduzieren, wobei du die Erweiterung Gradle for Java und den Java Language Server verwendest. Vergleiche das anfängliche Laden mit dem erneuten Laden oder Öffnen nach dem Ausführen von "Java: Clean Java Language Server Workspace"; abgeschlossen ist die Aufgabe, wenn das Projekt konsistent bleibt, ohne den Arbeitsbereich erneut zu bereinigen.
