Resources (application.properties) automatically deleted from bin folder shortly after generation in Gradle project

Describe the bug
In a Gradle multi-module project environment, the application.properties file is correctly auto-generated/copied into the bin/main folder after a "Clean Java Language Server Workspace" command or project build. However, after approximately 5-10 seconds, the file is automatically deleted from the disk without any user interaction.
To Reproduce
Steps to reproduce the behavior:

1. Open a Gradle multi-module project in VS Code.
2. Run the command: Java: Clean Java Language Server Workspace.
3. Open the file explorer and navigate to the output directory (e.g., project/bin/main).
4. Observe that application.properties is generated.
5. Wait for about 5 seconds.
6. The file disappears from the folder automatically.

Expected behavior
The language server should copy resources from src/main/resources to the output folder and ensure they persist there for the application to use during runtime and debugging.

Environment

• Operating System: Windows 11
• JDK version: 25
• Visual Studio Code version: v1.104.0
• Java extension version: v1.54.0

Additional Information

• This issue occurs specifically in a Gradle setup where the Language Server (Eclipse JDT.LS) seems to have a conflict with the internal build/sync process.
• Attempting to set a separate output folder (e.g., bin/main/) results in a "Cannot nest output folder" error.
• The logs show a warning: WARNING: Reflective call to EquinoxBundle#getModuleClassLoader(boolean) detected.
• A temporary workaround is manually running .\gradlew.bat processResources, but the file is eventually deleted again by the language server's background synchronization.

Reproduzca el problema en un proyecto Gradle multimódulo de Windows 11 con Java: ejecute Clean Java Language Server Workspace y, después, inspeccione los registros del servidor de lenguaje mientras compara el contenido generado de bin/main con .\gradlew.bat processResources. Use como punto de partida el comportamiento notificado de la carpeta de salida y de la sincronización. Se considera completado cuando application.properties permanece en la carpeta de salida después de la sincronización en segundo plano y está disponible para la ejecución y la depuración.
