Are you being driven mad by the horrible non-retina font rendering of Eclipse on a retina MacBook Pro? Fortunately, there is a workaround:
Open Finder and right click on the Eclipse.app then select “Show package contents”. Edit Contents/Info.plist file in a text editor and add lines 5 + 6.
1 <dict>
2 <plist>
3 ...
4
5 <key>NSHighResolutionCapable</key>
6 <true/>
7
8 </dict>
9 </plist>
Then, log out or make a copy of the app so that OSX will notice the change. Launch Eclipse and it should now be retina.
