问题
Installed eclipse and Java8. But it isn't working. When try to run it following error occur.
An error has occurred. See the log file /home/shield/.eclipse/org.eclipse.platform_3.8_155965261/configuration/1526718159168.log
I checked the log file and found these lines:
** !ENTRY org.eclipse.equinox.launcher 4 0 2018-05-19 13:40:07.262
!MESSAGE Exception launching the Eclipse Platform:

Just went through same issue with Ubuntu 18.04. Don't know specific answer but reinstalling directly from eclipse.org (C/C++ installer) eclipse-cpp-oxygen-3a-linux-gtk-x86_64.tar.gz went well. No more issues. Installing at Ubuntu 16.04, no issues found with synaptic installation either. So, just use eclipse installer in newest Ubuntu.
