I just installed Eclipse IDE using Ubuntu Software Center and Synaptic, but in both cases it don't shows for example "Java Project" in the wizard (File > New), just shows General and CVS. How can I fix that?
It seems you have installed just eclipse-platform. For Java development you need to install:
apt-get install eclipse-jdt
I run in a terminal sudo eclipse -clean with this I could see the other resources, then close eclipse and run again eclipse normally and let me see the other projects. Maybe this work for others.
