Reviewing the Debian equivalent people have suggested that: $ sudo apt-get install --reinstall libequinox-osgi-java
Could resolve the issue. Although some people note that it does not help. Others have recommended completely removing Eclipse as installed through apt and instead using the version supplied directly on the Eclipse CDT webpage https://www.eclipse.org/cdt/ I shall try both solutions this afternoon if there are no alternatives suggested that people would like me to try. ** Bug watch added: Debian Bug tracker #891956 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=891956 ** Also affects: eclipse (Debian) via https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=891956 Importance: Unknown Status: Unknown -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to eclipse in Ubuntu. https://bugs.launchpad.net/bugs/1784358 Title: Eclipse not starting with org.eclipse.equinox.launcher.Main.main java.lang.ClassNotFoundException being issued after updgrade to 18.04 Status in eclipse package in Ubuntu: New Status in eclipse package in Debian: Unknown Bug description: I upgraded from 16.04 to 18.04 on Friday. Following some reboots and updates this morning I am now unable to start the Eclipse IDE. This was working before the upgrade. I have the C++ developer support added to Eclipse. To the best of my memory (and ability to interrogate apt) it is all installed from the Ubuntu repositories. When I click the Eclipse launcher pinned to my side bat I get an error message from Eclipse that reads: An error has occurred.
