hi,
i have a problem with juno , i install it and when i try to run the .mwe2 file as a workflow i have the following error:

  *ATTENTION*
It is recommended to use the ANTLR 3 parser generator (BSD licence - http://www.antlr.org/license.html).
Do you agree to download it (size 1MB) from 'http://download.itemis.com/antlr-generator-3.2.0.jar'? (type 'y' or 'n' and hit enter)


and when i click 'y' the download start and i have the following error appearing:

 *ATTENTION*
It is highly recommended to use ANTLR's parser generator (get it from 'http://xtext.itemis.com/'). 
As an alternative to ANTLR you could also use the alternative implementation shipped with Xtext.
To do so use the generator fragment 'org.eclipse.xtext.generator.parser.packrat.PackratParserFragment' in your mwe2 file instead.(Element: -UNKNOWN-; Reported by: -UNKNOWN-)

There's a copyright issue that keeps us from deploying the antlr
generator plugin from an official Eclipse site. Xtext tries to download
it on demand when it's missing, which went wrong in your case (firewall?
flaky connetion?)

If you point your update manager to
http://download.itemis.com/updates/releases/
and install the Xtext Antlr feature, you will never be asked again.
