"Sources directory is already netbeans project" error when opening a project from existing sources

Thank you!

I was having the same problem:
Sources directory is already NetBeans project (maybe only in memory).

Netbeans creates a folder in your project named "nbproject". Once you delete that, restart the IDE and you're good to go.
