Project manager should warn when two projects share the same groupId and artifactId

Is your feature request related to a problem? Please describe.

I have a workspace of multiple Java projects. When two projects share the same groupId and artifactId, one of them do not get recognized by Project Manager, and thus not able to get built and debugged.

Describe the solution you'd like

In the case, project manager should either support it or throw error about it, instead of silently doing nothing.

Describe alternatives you've considered

I have to remove one of the projects from the same workspace to get the other loading.

Comienza localizando la lógica de Project Manager en el repositorio vscode-java que identifica los proyectos mediante groupId y artifactId; después, reproduce el problema con dos proyectos Java que compartan ambos valores en un mismo espacio de trabajo. Se considerará completado cuando los proyectos sean compatibles entre sí o cuando Project Manager muestre un error explícito en lugar de ignorar uno silenciosamente.
