What happened?

Answer 1

The version of Eclipse you are trying to use (probaby 3.8 or 4.2 judging by the plugin ids) is very old and doesn't understand Java 9. The layout of the Java 9 JRE/JDK directories has changed significantly and this is confusing this old Eclipse.

Use Eclipse Oxygen.2 4.7.2 to run with Java 9 or use Java 8 to run the old version of Eclipse.
