Build Identifier: 20100218-1602 I'm creating a MyDsl project and trying to run the MWE2 workflow.

It seems that it has to do with the whitespace in the path. Can you confirm this, i.e. does it work if you remove the whitespace in the path?
No, unfortunately I'm getting the same problem in a workspace with a filesystem path without whitespaces. And also, while I'm at it, I'm getting the following error when trying to generate an existing project: 0 [main] INFO eclipse.emf.mwe.core.WorkflowRunner - -------------------------------------------------------------------------------------- 12 [main] INFO eclipse.emf.mwe.core.WorkflowRunner - EMF Modeling Workflow Engine 1.0.0, Build v201005250425 13 [main] INFO eclipse.emf.mwe.core.WorkflowRunner - (c) 2005-2009 openarchitectureware.org and contributors 13 [main] INFO eclipse.emf.mwe.core.WorkflowRunner - -------------------------------------------------------------------------------------- 13 [main] INFO eclipse.emf.mwe.core.WorkflowRunner - running workflow: /Users/johan/Development/migration/XtextRC2/some/project/and/path/GenerateAbc.mwe 14 [main] INFO eclipse.emf.mwe.core.WorkflowRunner - 709 [main] INFO lipse.emf.mwe.utils.StandaloneSetup - Registering platform uri '/Users/johan/Development/migration/XtextRC2' Exception in thread "main" java.lang.SecurityException: class "de.itemis.xtext.antlr.AntlrToolRunner"'s signer information does not match signer information of other classes in the same package at java.lang.ClassLoader.checkCerts(ClassLoader.java:807) at java.lang.ClassLoader.preDefineClass(ClassLoader.java:488) at java.lang.ClassLoader.defineClassCond(ClassLoader.java:626) at java.lang.ClassLoader.defineClass(ClassLoader.java:616) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:141) at java.net.URLClassLoader.defineClass(URLClassLoader.java:283) at java.net.URLClassLoader.access$000(URLClassLoader.java:58) at java.net.URLClassLoader$1.run(URLClassLoader.java:197) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:248) at org.eclipse.xtext.generator.parser.antlr.AntlrToolFacade.getToolClass(AntlrToolFacade.java:48) at org.eclipse.xtext.generator.parser.antlr.AntlrToolFacade.isWorkable(AntlrToolFacade.java:133) at org.eclipse.xtext.generator.parser.antlr.AbstractAntlrGeneratorFragment.checkConfiguration(AbstractAntlrGeneratorFragment.java:42) at org.eclipse.xtext.generator.parser.antlr.XtextAntlrGeneratorFragment.checkConfiguration(XtextAntlrGeneratorFragment.java:52) at org.eclipse.xtext.generator.CompositeGeneratorFragment.checkConfiguration(CompositeGeneratorFragment.java:211) at org.eclipse.xtext.generator.LanguageConfig.checkConfiguration(LanguageConfig.java:74) at org.eclipse.xtext.generator.Generator.checkConfigurationInternal(Generator.java:83) at org.eclipse.emf.mwe.core.lib.AbstractWorkflowComponent2.checkConfiguration(AbstractWorkflowComponent2.java:21) at org.eclipse.emf.mwe.core.container.CompositeComponent.checkConfiguration(CompositeComponent.java:142) at org.eclipse.emf.mwe.core.WorkflowRunner.prepare(WorkflowRunner.java:346) at org.eclipse.emf.mwe.core.WorkflowRunner.run(WorkflowRunner.java:290) at org.eclipse.emf.mwe.core.WorkflowRunner.main(WorkflowRunner.java:241) 2870 [main] INFO ipse.xtext.generator.LanguageConfig - No explicit fileExtensions configured. Using '*.abc'. How do I solve that? If it's a bug and not related to this, I can create another issue.
I could reproduce the first issue and am pretty sure it had to do with special characters in the URL. Could you please double check the URL or post it here? We are aware of the second problem, which is why we have to do an RC2a tonight. :-(

Ok, sorry this is getting a bit messy... The situation is that we had a problem with the signing that occured because we use the same package in a signed jar as well as an unsigned jar (which classloaders do not like). Hence this is the second problem you also faced. In order to solve this I had to rename a package in the de.itemis.xtext.antlr jar which I already have uploaded in order to test it. You are no downloading the new jar with renamed package, but calling it from yesterday's RC2 version which points to the old package name. As a result you get a class not found exception. A bit complicated but I hope I was able to explain it. Anyway, I have fixed both issues, though you'll have to wait for tonight's builds or configure a different AntlrToolRunner (i.e. the one from HEAD) into your MWE2 file : fragment = XtextAntlrGeneratorFragment { antlrTool = MySpecialAntlrToolFacade {} }
Closing bug which were set to RESOLVED before Eclipse Neon.0.
