Hello,

When I attempt to generate the Xtext artifacts by running the mwe2 file, I recieve the following error:

Downloading ANTLR parser generator failed: Server returned HTTP response code: 504 for URL: htttp://download.itemis.com/antlr-generator-3.2.0-patch.jar
Please install the feature 'Xtext Antlr SDK' manually using the external updatesite:

'htttp://download.itemis.com/updates/'.

And even the link it give me it impossible to join manually

Thank you for your help

Same here. As far as I can see, the download server is down again, to let those who are affected know.
@Christian Dietrich I'm going to write to the official info@itemis eMail. Let's see who will handle this faster, you or the guys from the service office ;-)

Hi

What version of Java do you use?

I use java 8 and have not seen anything similar. The message suggests it is Java tightening up requiring longstanding code practices to be revised.
