I read a lot of topics on this issue here, but there is no answer anywhere.
After installing Eclipse, there is no shortcut.
~/.local/share/applications and in
/usr/share/applications/ with content:
[Desktop Entry] Encoding=UTF-8 Version=1.0 Type=Application Name=Eclipse IDE Comment=Eclipse Integrated Development Environment Icon=/home/n199a/eclipse/java-2020-06/eclipse/icon.xpm Exec=/home/n199a/eclipse/java-2020-06/eclipse/ X-Desktop-File-Install-Version=0.23
But shortcut not displayed anywhere.
If I change Properties -> Permissions -> 'Allow executing file as program' (checkbox ON) I get error message
There was an error launching the application.
