*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-)
[ERROR]:  


i think there is a connectio problem when eclipse is trying to download the ANTLR's parser generator from Itemis website, so i have decided to use the alternative possibility, means use the alternative implementation shipped with Xtext.
by using the generator fragment 'org.eclipse.xtext.generator.parser.packrat.PackratParserFragment' in your mwe2 file instead.

but i dont' know where that fragment is implement , i have tried to modify ithis 2 following file but nothing change:

 fragment = generator.GeneratorFragment {
                    generateMwe = false
                    generateJavaMain = false
                } 

and

 fragment = parser.antlr.XtextAntlrGeneratorFragment {
                //  options = {
                //      backtrack = true
                //  }
                } 


i have also tried another solution , this by downloading the ANTLR's parser generator directly by myself in the itemis website without the help of eclipse , but the problem is , i don't know where to put that jar file downloaded . i have tried to add it in the plugin package or the features package but nothing change .

so i will be very gratefull for any contribution.


king regards,
Frank

You can put the jar in your projects root folder.
<your_peoject_loc>/.antlr-generator-3.2.0.jar

Don't forget to rename the jar to .antlr-generator-3.2.0.jar (starts with a dot) Confused

But the better sollution is to install Xtext Antlr Runtime Feature 2.0.0
from http://download.itemis.de/updates/releases/2.0.0

Are you using windows? Laughing
Put the file in your projects root as is, than rename it using eclipse itself hit <F2> or "Refactor->Rename" rename to .antlr-generator-3.2.0.jar ... and than install linux or an another unix OS Smile

Did you try to install the antlr feature from
http://download.itemis.de/updates/releases/2.0.0 as Dennis suggested?

This question has been answered a lot of times in this forum:
Roughly: Load the resource -> Create an XMI/XML resource -> copy the
contents -> save the XMI/XML resource.

For more information, use the search facility.

As I said, use the search facility on this forum. 'XMI' will get you a
lot of useful information.

I have since yesterday, the same problem as Frank in 2012. (It seems that the site itemis.de is down) Where can I download the file antlr-generator-3.2.0.jar yet? Do you have another place to download the file?

Could you please confirm that itemis.de is available again?
