I’ve installed NetBeans 6.9.1 and installed few updates for it.
Then I’ve created a new project from existing sources. After a few changes I’ve closed it. And now I am having an error, when trying to open a new project from existing sources (the same files):
Sources directory is already netbeans project (maybe only in memory).
After Googling it, I noticed it happened not only with me. But I didn’t find the correct solution. I’ve tried to restart the IDE, I’ve tried to restart the PC, I’ve tried to reinstall NetBeans. Nothing helped.
When you create a NetBeans project from existing sources, NetBeans uses the same directory to add its own files: a
netbeansfolder with .proj files.Solution: delete the
netbeansfolder and restart the IDE. Opening a new project should now work.
