You need to do the following:
- Go to the project structure dialog (either by clicking the warning or through file=>project structure
- select the modules item in the left hand list
- go through and right click on the modules with missing files and select Add=>Spring
- in the new tab click the + button
- you should now see a list of the xml files. Check the boxes next to them
It’s not entirely clear to me what this achieves apart from getting rid of the warnings! If anyone could shed any light on that it’d be good.
