I have removed the spine extension from my game project. But each time I start the editor I get the following error message (in its own window):

The editor plugin ‘/.defold/assets/defold-spine/editor/src/spineguiext.clj’ is not compatible with this version of the editor. Please edit your project dependencies to refer to a suitable version.

And then a second similar error. I have already tried “Project → Fetch libraries”…

I would guess I have to manually delete some cached data in the project directory but I don’t know what. And I don’t want to destroy the project by deleting some wrong directory 🙂

Any help?

You could try closing Defold then deleting the ‘build’ and ‘.internal’ folders from within your project folder.

Then restart Defold. You might need to do the ‘Project → Fetch libraries’ thing again, not sure.
