Can't run Eclipse Luna

Question

I am new to Java world and I trying to setup Eclipse Luna so i can start using it. I have installed JDK 11.0.12 and Eclipse Luna but when I run Eclipse, from the workspace log file i can see the error:

Caused by: java.lang.ClassNotFoundException: org.w3c.dom.stylesheets.StyleSheet cannot be found 
 by org.eclipse.e4.ui.css.core_0.10.100.v20140424-2042

I have made some google research but without success. Any suggestion?

Answer 1

Luna is ages old. You are attempting to run Luna on JDK 11, which is not compatible:

You can downgrade your JDK and run Luna on that, if using Luna is unavoidable.

I am not sure how you did some research and did not find this information, if you copypaste your error message into Google, then the linked thread is literally the first result.
