ubuntu 在launcher添加软件运行图标（How to pin Eclipse to the Unity launcher?）

First, create a .desktop file to eclipse:

gedit ~/.local/share/applications/opt_eclipse.desktop

Then, paste this inside (dont forget to edit Exec and Icon values):

[Desktop Entry]
Type=Application
Name=Eclipse
Comment=Eclipse Integrated Development Environment
Icon=** something like /opt/eclipse/icon.xpm **
Exec= ** something like /opt/eclipse/eclipse **
Terminal=false
Categories=Development;IDE;Java;
StartupWMClass=Eclipse

After that, open that folder with nautilus:

nautilus ~/.local/share/applications

If you want to use this launcher outside dash/launcher (ex: as a desktop launcher) you need to add execution permission by right clicking the file and choosing Properties -> Permissions -> Allow execution, or, via the command-line:

chmod +x ~/.local/share/applications/opt_eclipse.desktop

Finally drop opt_eclipse.desktop to launcher.
