Create new Java project, java preferences unavailable

Question

I finished installing Eclipse 3.7.2 (Indigo) on my Ubuntu 12.04 system.

I am unable to have any options pertaining to either creating a Java project, running one as a Java project, can't find any of the Java preferences for JRE settings... There is no Java Development Toolkit in the Help section. I had all this earlier, I am not sure what changed. I am assuming that this has something to do with the SDK but have no other clue.

Answer 1

Install your preffered JDK, then go Preferences -> Java -> Installed JREs and point to the fresh install.

Also, check Preferences -> General -> Capabilities. Make sure you have Development selected.

Answer 2

You might not have a system JRE installed. Press ctl + alt + T to open your Terminal and then try running:

sudo apt-get install default-jre

Note: this will install Java 1.7, if you want 1.6 then you have to specify that

Then in Eclipse, make sure you have your environment setup correctly.
