Is Maven ready for JDK9?

Question

Today I tried the latest jdk9 Build 113 and tried to compile my project with the latest Maven 3.3.9

These are the commands (found partially via twitter)

Answer 1

Here is the answer from one Maven PMC member (me):

No, it is not. Robert Scholte is working on it. Jigsaw and other stuff introduced a lot of changes. There is no official timeframe where full compat (Maven + official plugins) will be given.

The issue you see is actually not Maven but Plexus Archiver. Refer to their GitHub page. If you think you can add value, contact maven-dev mailing list.
