Migratiion problem [message #940375]

Hello,

I'm trying to migrate a set of projects from xtext 1 to 2. When I run the MWE (not MWE2) workflow to generate my code I get an error telling me that:

The Antlr generator fragment couldn't be found on the classpath.

Normally it should ask me to download it but I don't even get that option. Everything just stops. I tried to get the plug in and it appears that I am importing all the libraries right libraries in the "Plug-in dependencies" list. I also tried to download the file myself, rename it and put it in the root of my project as explained in this post (http://www.eclipse.org/forums/index.php/m/896639/).

Is there a way I can set the classpath of MWE right for it to regenerate my code? Is there another solution?

Hi,

I just found a solution, I needed to replace this line:

<fragment class="org.eclipse.xtext.generator.AntlrDelegatingFragment" />

with this one:

<fragment class="org.eclipse.xtext.generator.parser.antlr.XtextAntlrGeneratorFragment" />

and also this other:

			<fragment class="org.eclipse.xtext.generator.DelegatingGeneratorFragment" 
				delegate="de.itemis.xtext.antlr.XtextAntlrUiGeneratorFragment"
				message="You are generating without ANTLR. It is highly recommended to download and use the plugin 'de.itemis.xtext.antlr' \n\t using the update site <link suppressed>.">
			</fragment>

with

			<fragment class="org.eclipse.xtext.generator.DelegatingGeneratorFragment" 
				delegate="org.eclipse.xtext.generator.parser.antlr.XtextAntlrUiGeneratorFragment"
				message="You are generating without ANTLR. It is highly recommended to download and use the plugin 'de.itemis.xtext.antlr' \n\t using the update site <link suppressed>.">
			</fragment>
