Cannot attach project in DataSpell

Question

On the welcome screen of DataSpell I chose to open a project with Get from Version Control to get a project from GitHub, although in the left pane I didn't choose GitHub, so it created an empty .git repository.

After that, I git cloned elsewhere the git repository or tried to clone it correctly from GitHub but in every occasion I get

Error
Cannot attach project Module name 'project name' already exists. 
Trying to load module: /path/to/project name.iml

Where does DataSpell save the imported projects, to detach the empty project that I imported initially?

Answer 1

I managed to open the project following the instructions of Open your project from disk section of the DataSpell site.

For avoiding further trouble, I opened the project in a new window. After the configuration in step 2 Reopen projects on startup --> Ask , Dataspell will ask how to open the project.

Answer 2

File --> Invalidate caches... --> INVALIDATE AND RESTART worked for me (with no options selected for the final step).

Answer 3

This has been happening to me more frequently in DataSpell 2022.3 on my M1 Apple machines. To solve the issue, I did the following:

• Settings > Project: [Project Name] > Project Structure .

• Click + Add Content Root and select the root folder of your project.

• Press Apply or OK

You should now see your project folder in the Files section of the Workspace.
