Edit Gnome shell launchers to point to another executable than default
For Example: You’ve installed Eclipse 3.7 „Indigo“ and want to change to Eclipse 4.3 „Kepler“ but you don’t want to delete your old „Indigo“ till you feel confident about „Kepler“.
I still don’t but after updating some plugins, all plugins and configurations disappeared. The bad thing on it: not being able to restore! So I moved on, and did what I’v started a view month ago: Migrate my Projects from Kepler to Indigo.
1. Copy Eclipse Indigo launcher to for example eclipse_kepler.desktop
$ cd /usr/share/applications $ sudo cp eclipse.desktop eclipse_kepler.desktop
2. Edit eclipse_kepler.desktop with an editor you’r familiar with and change file content like this
[Desktop Entry] Type=Application Name=Eclipse Kepler Comment=Eclipse Kepler Integrated Development Environment Icon=eclipse Exec=/PATHTOEXECUTABLE/eclipse Terminal=false Categories=Development;IDE;Java;
Make sure to change/edit Name and Comment to distinct „Kepler“ from “ Indigo“, or if time doesn’t mater, find anonther Icon and replace the default.
