Newly created projects do not show correct package structure when created outside of the workspace

I'm unsure if this is a bug in Eclipse because I cannot find any difference in, e.g., `MANIFEST.MF`, `.project` etc.
However, supposes one creates a new GIPSL project and chooses a location *outside* of the current workspace (e.g., to create a new project in an existing git repository). In that case, Eclipse does not display the package hierarchy inside `src-gen` correctly.
Therefore, all builds of the generated code fail.
