Hey there,

until yesterday I used Ubuntu, but Unity was not my thing, now I’m using Elementary OS 0.3 beta1 and need to get my stuff working again. Luckily since the base of both systems is the same, it is fairly easy and alot of guides for Ubuntu 14.04 LTS work just fine :).

Prepare for installation

First grab a Java runtime environment by installing openjdk apt-get install openjdk-7-jdk.
Done!

Getting and Setting Eclipse

Well head to http://www.eclipse.org and grab the latest version.
Unpack to /tmp and move the folder with mv /tmp/eclipse /opt .

We are nearly there! Now we want a Desktop Entry to start Eclipse via the launcher. So create a new file at vim ~/.local/share/applications/eclipse.desktop with the following content:

[Desktop Entry]
Version=4.4.0
Name=Eclipse
Comment=Eclipse IDE
Exec=/opt/eclipse/eclipse
Icon=/opt/eclipse/icon.xpm
Terminal=false
Type=Application
Categories=Development;Application

Enjoy!
