Installing Eclipse Oxygen On Ubuntu 16.04

Question

I downloaded Eclipse Oxygen from https://www.eclipse.org/downloads/ and went through the installation process, but after installing when I click "eclipse" at /home/rizwan/eclipse/java-oxygen/eclipse, it should open IDE but I am not able to open the IDE it shows:

Answer 1

Review eclipse.ini. Remove duplicate entries and remove --add-modules lines. After such cleanup eclipse started for me on openjdk9. Not sure if I will face some other issues, will report back.

EDIT: After checking java -help it turns out that there is an option -addmods which was in an early access of Java 9. Now it's called --add-modules. Seems like the jdk in ubuntu repo is quite old (explains why it's called 9-internal)

EDIT2: As suspected: https://packages.ubuntu.com/search?keywords=openjdk-9-jdk
