Can't resolve jvmType reference to file in project (using maven) [message #1661283]

Hi..
I need your help, fixing an issue with JvmType references to files in the current project.
For some reason, they don't seem to work when compiling the project with maven (so, using the StandaloneSetup).

I get the following:
ERROR:Couldn't resolve reference to JvmType

Everything is fine when working on the project in Eclipse. It's just our CI build that fails...

I did some extensive research into the issue, but couldn't figure out how to fix this. My guess is, that the file simply isn't compiled yet (i.e. not present in target/classes) thus Xtext can't find it.

The weird thing is, that I think it did work before...

Thanks

Patrice

Hey Patrice,

please attach the buildscript, project layout and the source file in questions. Without this information, it is almost impossible to help.

Best Regards,
Stefan

I can try.. It's a rather complex project, but I should be able to whip up a small example project.

What exactly do you need? The pom and the model files?

Here we go.

The layout is a standard maven layout:

./src/main/java/de/bitzeche/test:
TestClass.java

./src/main/resources:
test.idef	test.impl

./:
pom.xml

The procedureParam is defined as follows (simplified):

ProcedureParam:
	type=SimpleType name=ID
;
SimpleType:
	javaType = [jvmTypes::JvmType|FQN]
;

And here's what I get when I try to compile it on the command-line:

...

Your configuration looks fine at first glance. Could you run maven in debug (-X) mode and attach the relevant output? It will tell you more details about which paths and files were used.

[WARNING] source level should be comprised in between '1.3' and '1.7'

Seems like there is an older version of JDT on the classpath that doesn't support Java 8 like you specified in your POM. Either use Java 7 or update your dependencies.

hmm.. That would make sense..

Isn't that an issue with the text-maven-plugin, though? JDT comes packaged with it

I can confirm, that it works with source level 1.7, so it's definitely an issue with Java 8

Indeed, Xtext 2.7.3 shipped with jdt.core 3.7, which can only handle Java 7.

Xtext 2.8 fixes that problem.

Ok. Time to move to 2.8 then.

Which introduces a new issue: Now eclipse can't resolve the jvmTypes either due to the TypesAwareDefaultGlobalScopeProvider not being used in the generated DSLRuntimeModule...
Guess that's a bug?

Update:
I should be more precise.

The generated AbstractDSLRuntimeModule overwrites the bindIGlobalScopeProvider method from DefaultCommonTypesRuntimeModule (which uses the proper provider):

// contributed by org.eclipse.xtext.generator.scoping.AbstractScopingFragment
	public Class<? extends org.eclipse.xtext.scoping.IGlobalScopeProvider> bindIGlobalScopeProvider() {
		return org.eclipse.xtext.scoping.impl.DefaultGlobalScopeProvider.class;
	}

Yes that looks like a bug, can you please file it? =)

As a workaround, add the correct binding to your RuntimeModule

That's what I ended up doing.

It totally works with Xtext 2.8 Smile

Thanks Stefan for your help!!!
