Generation error after upgrading xtext [message #1696107]

Thu, 21 May 2015 16:26

Eclipse User

Hello,

I recently upgraded Xtext to 2.8.2 and when trying to generate the language artifacts, I got the following exception. Is there anything to do to upgrade the language? Is this bug/issue known?

Thanks for any help.

Julien.

Hi,

which version of the antlr generator do you have installed? if none: which one is stored under the name .*antlr*.jar in the root of the runtime project. if there is such a file (may be hidden) then move it out of the way and restart the workflow.

Seems that I have version 3.2 installed. See below.

Also, in the root of my project, I have a patch. See

[julien@masaru]/home/julien/git/alisa#find . -name '*antlr*.jar' 07:33:58
./org.osate.reqspec/.antlr-generator-3.2.0-patch.jar

[julien@masaru]/home/julien/git/alisa#find . -name '*antlr*.jar' |xargs rm -f 07:34:10
[julien@masaru]/home/julien/git/alisa#

If I am trying to delete them, the error is still there. The problem happens only with one project, other seems to be ok. Any other workwround/suggestion about how to investigate that?

Hi,

if you have no antlr generator installed (this is the case) then the .antlr-generator-3.2.0-patch.jar is used.
(did you remove both of them?)
what you could to is to create a new project with the wizard and paste your grammar there.
thus you can find out if it is a bug or a problem with your setup

btw wich xtext version are you migrating from?

btw if you have a look at the class file it complains about: is the method there or is it not?

I will investigate. I am using xtext 2.8.2 and migrate from xtext 2.8.0

Yes, I deleted both patch files. Also, I cannot see if the function is defined because I do not have the sources.

such minor version updates should work straight forward.

I am trying to update to 2.9.0, let's see if it addresses the issue.

Exactly the same issues - any way to investigate more ? Do you recommend to install a specific antlr version?

Can you share a minimal grammar that reproduces the problem.

P.s.you tried a new xtext project as well?

It is not reproducible with a small projects. It seems that it happens when I have a project that references other grammar. Will try a new project.

I was able to reproduce the bug. I put it on the following github project. https://github.com/juli1/xtext-debug
Also, this is the trace I get when trying to generate the grammar

Hi this is a completely different error. Are you sure you installed uml sdk

Hi,

first of all you should clean up the workflow. only register packages that are on classpath and that you actually use

    bean = StandaloneSetup {
    	scanClassPath = true
    	platformUri = "${runtimeProject}/.."
    	// The following two lines can be removed, if Xbase is not used.
    	registerGeneratedEPackage = "org.eclipse.xtext.xbase.XbasePackage"
    	registerGenModelFile = "platform:/resource/org.eclipse.xtext.xbase/model/Xbase.genmodel"
//		registerGeneratedEPackage = "org.eclipse.emf.ecore.EcorePackage"
//		registerGeneratedEPackage = "org.eclipse.uml2.types.TypesPackage"
//		registerGeneratedEPackage = "org.eclipse.uml2.uml.UMLPackage"
//		registerGeneratedEPackage = "org.eclipse.emf.codegen.ecore.genmodel.GenModelPackage"
//		registerGeneratedEPackage = "org.eclipse.uml2.codegen.ecore.genmodel.GenModelPackage"
//		registerGenModelFile = "platform:/resource/org.eclipse.emf.ecore/model/Ecore.genmodel"
//		registerGenModelFile = "platform:/resource/org.eclipse.emf.codegen.ecore/model/GenModel.genmodel"
//		registerGenModelFile = "platform:/resource/org.eclipse.uml2.types/model/Types.genmodel"
//		registerGenModelFile = "platform:/resource/org.eclipse.uml2.uml/model/UML.genmodel"
//		registerGenModelFile = "platform:/resource/org.eclipse.uml2.codegen.ecore/model/GenModel.genmodel"
//		registerGeneratedEPackage = "org.osate.aadl2.Aadl2Package"
//		registerGenModelFile = "platform:/resource/org.osate.aadl2/model/aadl2.genmodel"
    }

next you should get rid of the ambiguities

XNumberLiteral returns xbase::XNumberLiteral :
	{XNumberLiteralUnit} value=Number //? - the problem is the ? in your grammar
	;

yep - sorry - I managed to reproduce it again. In fact, it happens when I import another genmodel and package. When I insert a dependency to another project. (the org.osate.xtext.aadl2)
What dependencies/features of this project might then cause that?

sorry i cannot say that. there may be something wrong with the classpath. or a bug in xtext or antlr.
but with reproducing hard to say

More clue about it - a colleague of mine has the same sources on a windows machine - it works ok. Turns out that it does not work on mine (linux debian x64)

Please make sure that org.antlr.runtime_3.1.b1_3.1.0.jar is not on the
classpath of the mwe2 execution.

Best,
