Hi Fred

Who is "we"? Which project? The Platform/JDT is done. RC2 was last Friday.

Hi, 

we just found out the cause of bug 
https://bugs.eclipse.org/bugs/show_bug.cgi?id=522333, which prevents you 
from running Maven builds on Java 9 projects on Windows specifically.

Java 9 no longer supports classpaths sent with the form /c:/whatever 
(worked in previous Java versions) as sent by m2e.
I believe we can provide a fix today. Is it possible to delay the 
Oxygen.1a RC2 aggregation builds to tonight?

Fred

Ah, Java Development Tools Launching Support is at 3.9.50.v2070925-1051 in 
that latest EPP build which might just not yet include the fix from the 
same day.

I'll see if I can workaround it on m2e's side for RC2. Not promising any 
miracles though.

Doesn?t seem fixed to me.

Hi all
 
As the RC2 window already closes and the final Oxygen.1a contributions are 
due soon, I bring up the following issue directly on this list:
 
On the EPP RC1 with only a JDK 9 as installed JRE, calling Maven commands 
fails with
Error: Could not find or load main class 
org.codehaus.plexus.classworlds.launcher.Launcher
Caused by: java.lang.ClassNotFoundException: 
org.codehaus.plexus.classworlds.launcher.Launcher
Switching to a JDK 8 resolves the problem.
 
Steps to reproduce:
*New workspace
*File/New Other?/Maven/Maven Project/Create dummy project
*Select project folder/Right click/Run As?/Maven clean
 
I?ve reproduced this under Windows 7 and the Scout EPP package. To make 
sure it isn?t a Scout issue I?ve tested with a post RC1 EPP package of 
Eclipse Java too.
 
Has anyone else experienced this? Is anyone else able to reproduce it?
 
Thanks and regards
Arthur
