How to upgrade Eclipse Juno 4.2 to Eclipse Kepler 4.3 on Mac OS X

These instructions should be similar for upgrading to Eclipse Kepler 4.3 on other operating systems as well.

 

  • Scroll down to Platform Runtime Binary and download Mac OSX (Mac/Cocoa/x86_64) eclipse-platform-4.3-macosx-cocoa-x86_64.tar.gz.

 

  • Extract the archive and rename the new eclipse folder to eclipse4.3 or, whatever makes sense for you.

 

  • Move the eclipse4.3 folder to the applications folder. Make sure Eclipse Juno 4.2 is not running, then run Eclipse.app int the eclipse4.3 folder.

 

  • Typical security. Click Open. You may need to temporarily change your security pref to be able to run this app to ‘Anywhere’.

 

  • Select your normal workspace.

 

  • You’ll probably see a lot of errors since none of the plugins are installed yet. I use PDT.

 

  • Go to File -> Import…

 

  • Choose From Existing Installation then click next.

 

  • Browse to your Eclipse 4.2 installation and click Open. You should now see all the plugins / extensions. Then click next.

 

  • Review your Install Details and click next if everything looks correct.

  • Accept the terms and click finish.

  • You may get a warning about unsigned content. If it’s fine, click OK.

  • Restart your new Eclipse Kepler 4.3 installation and you should be ready to continue development where you left off with Eclipse Juno 4.2.
