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.
