Spring Tool Suit: Trying to delete a folder within a web app

Question

Within my project I need to delete a folder, but everytime I try to I get this message:

Resource 'ProjectTemplate/node_modules' is out of sync with file system

I had issues deleting the entire folder, that I tried to delete individual folders within node_modules with success, but now I get another error.

Any help is greatly appreciated. Thanks

Answer 1

right click the folder and select Refresh. I tried that multiple times, but another attempt allowed me to delete the folder.
