Sources directory is already NetBeans project error

Question

i got that error and i can't add project in netbeans.. please teach me how to fix this

even if i rename my folder it doesn't work...

Answer 1

Netbeans tries to add a folder (nbproject) to your project during import. If it is already there NB fails to add it. Move the existing nbproject folder to a different directory outside your project and try to import again.

See this question.

Answer 2

Delete the nbproject folder in your project directory and restart the IDE.

Answer 3

I had a PHP project with maven pom.xml, with no nbproject directory and clear cache, and netbeans would refuse to create a new project from sources with that pom.xml in place. Had to remove pom.xml, create a project and put pom.xml back.
