Ubuntu – Eclipse has two icons on unity launcher when I only want one

eclipseunity

I recently upgraded to Eclipse Luna and since then I've had trouble launching it from the Unity Launcher. I've modified my old .desktop file located in ~/.local/share/applications, then added it to my launcher and now it looks like this:

How can I fix this?

For reference, here's my eclipse.desktop file:

#!/usr/bin/env xdg-open
[Desktop Entry]
Version=1.0
Type=Application
Terminal=false
Path=/home/jinkim/eclipse
Icon=/home/jinkim/eclipse/icon.xpm
Exec=/home/jinkim/eclipse/eclipse
Name=Eclipse Luna
Comment=This is an IDE
Icon=eclipse

  • It seems there a line in the .desktop file that I was missing. In particular, the crucial line seems to be:

    StartupWMClass=Eclipse
    

    More info on that here: What represent the StartupWMClass field of a .desktop file?

    So, I have found what works for me below:

    #!/usr/bin/env xdg-open
    [Desktop Entry]
    Name=Eclipse
    GenericName=Eclipse Java IDE
    Comment=Eclipse Java IDE
    Categories=Utility;Developer Tools;IDEs;Java;
    Exec=/home/(your-username-here)/eclipse/eclipse
    Icon=/home/(your-username-here)/eclipse/icon.xpm
    StartupWMClass=Eclipse
    StartupNotify=true
    Terminal=false
    Type=Application
    X-GNOME-FullName=Eclipse Java IDE
    

    The steps I took to get this working are:

    1. Use a text editor to create eclipse.desktop, and paste the above into it

    2. Move eclipse.desktop into ~/.local/share/applications

    3. Allow it to be executable: chmod +x eclipse.desktop

    4. Double-click eclipse.desktop which should appear in Nautilus as Eclipse

    5. In Unity launcher, right-click and select "Lock to Launcher"
