Pure NetBeans doesn't work

I had system: ubuntu-9.04-amd64. I installed IDE NetBeans 6.5 from official default repositories. Everything worked correctly.

But now, I decided to use ubuntu-9.10-desktop-amd64.

I formated parts of my hard with: (/ and /usr). /home remains as before. I've correctly installed ubuntu-9.10, correctly (probably) installed IDE NetBeans 6.5.

But NOW, I even can't create simplest java application using this IDE. If I use CommandLine to compile java classes, everything works (~/javac someclass.java | java).

If I launch IDE (NB 6.5), then File->New Project-> This New Project is created, but isn't compiled: if put (F6) error is shown:

What can I do to compile simplest application using IDE. I must make my work, please help me.

Your problem looks to be related to https://bugs.launchpad.net/ubuntu/+source/netbeans/+bug/401589.

My understanding is that there are actually 2 solutions:

• Install NetBeans 6.7 without importing the settings from 6.5 (this would be my recommendation).
• Downgrade libnb-javaparser-java 6.7-0ubuntu1 to 6.5-0ubuntu1.
