Custom launchers

The applications launchers Gnome knows about are .desktop files in /usr/share/applications, and ~/.local/share/applications. You can create custom launchers for whatever is in your home folder, by either manually creating and editing a custom .desktop file, or by using Alacarte, the old Gnome menu editor.

The Gnome desktop file documentation can be of help: https://developer.gnome.org/integration-guide/stable/desktop-files.html.en

The custom launcher is just a text file, named, for example, EclipseEE.desktop, with the following content:

[Desktop Entry]
Name=Eclipse EE
Exec=/home/mrPeterson/path_to_executable
StartupNotify=true
Terminal=false
Type=Application
Icon=/optional/path/to/icon.png
