Re: [xtext-dev] ClassNotFound exception when running against Xtext 2.10
|
Hello,
Unfortunately I was wrong in my previous answer. This is still happening even when building and launching from Eclipse Neon with latest m2e plugins.
We are using Tycho version 0.22.0, albeit this issue is seen when building and launching from within Eclipse itself.
Thanks for your help,
/M

Hello Jeff,
Thanks for your tip. The problem is resolved when launching from an Eclipse Neon running m2e version 1.7.0.20160603-1933.
I was previously working with an Eclipse Mars instance using an older version.
Kind regards,
/M
