<language>.xtextbin not found [message #1066232]

Hi all,

I'm observing a really strange behavior.

The eTrice project uses Xtext 2.4.0 for quite a while now.
Today I switched to Xtext 2.4.2.

eTrice has code generators that read (Xtext) model files and generate code.
All that still works fine with Xtext 2.4.2.

There is only a problem I observe in a unit test where we invoke the generator from an Ant script (s.b.).
It seems that all classes can be loaded.
Only the new <language>.xtextbin files can not be found even though they are obviously there.
(I have seen that the first try of org.eclipse.xtext.service.GrammarProvider.getGrammar(Object) is to load <language>.xtextbin
(which is there in my case) and the second try is <language>.xmi (which doesn't exist after I generated with Xtext 2.4.2).)

I assume this is some kind of class loader issue but I can't figure out how to resolve it.

Does anybody else observe this issue?

Thanks,
Henrik

Hi,

did you update oder a fresh install,

maybe the old classes are on classpath as well

its a fresh install. I've started with a Kepler modeling package and I've double checked:
there are only Xtext 2.4.2 plug-ins on the class path.

When I launch the generator as Java Application in Eclipse it works.
It fails when I use the Ant script.

Hmmmm strange,

you may have a look at org.eclipse.xtext.service.GrammarProvider.getGrammar(Object)
for further investigation.

are you sure the xtextbin file goes to the bin directory?

Hi Christian,

I narrowed down the o.e.x version to 2.4.2 as you did below (I required only 2.*).
And it turned out that my platform path still pointed to a Juno installation :-/

Now it works just fine as before.

Thanks for your help,
Henrik

I just spent a couple of hours chasing down a variant of this problem:

In my development IDE I use Xtext 2.4.2 and I want to deploy the DSL plugin into an IDE using the same Xtext version. Only, the application that uses the DSL's generator cannot yet depend on Xtext 2.4.2 in its maven build (because our nexus doesn't yet provide this version, and because application dependencies always evolve more slowly than tool versions - in fact the application build still refers to Xtext 2.3, which should be OK since the generator shouldn't depend on any newer features).

Result: the DSL was generated into the new MyDSL.xtextbin and the invocation of the generator failed because it could not load the MyDSL.xmi.

Question: what's the recommended way of using Xtext 2.4.2 for creating a generator that can run on earlier versions of Xtext? Is there a way to tell Xtext 2.4.2 to generate the "old" MyDSL.xmi file?

thanks,
Stephan

Hi,

did you try to force the xml to be created?

    		fragment = grammarAccess.GrammarAccessFragment auto-inject {
    			xmlVersion = "1.0"
    		}

Hi

It would be nice if the GrammarAccessFragment.setXmlVersion method had a
comment explaining the role of the setting.

Intuition would suggest that it was a way to specify the XML version as
1.1 rather than 1.0. Who would want to do that?

Regards

Thanks Christian, I will try this first thing on Monday.

Dude, you must be reading that code a lot. It seems like I could have benefited from a migration guide for 2.4.2, as suggested in another thread. Never thought that updating to a service release would require such...

thanks,
Stephan

For posterity: yes, specifying xmlVersion did help in my case, as it ensures that .xmi is used, no matter which Xtext version is used. And: it needn't be "1.0", setting the version to "1.1" achieves the same result Smile

cheers,
Stephan
