By the way, I can reproduce this problem also by modifying this test in
the domain model example and run it as a Junit plugin test:
package org.eclipse.xtext.example.domainmodel.tests
import org.eclipse.xtext.example.domainmodel.DomainmodelUiInjectorProvider
import org.eclipse.xtext.junit4.InjectWith
import org.eclipse.xtext.junit4.XtextRunner
import org.junit.Test
import org.junit.runner.RunWith
@RunWith(typeof(XtextRunner))
@InjectWith(typeof(DomainmodelUiInjectorProvider))
class CompilerTest {
@Test
def void testGeneratedJava() {
}
}
and here's the trace
java.lang.LinkageError: loader constraint violation: loader (instance of
org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader) previously
initiated loading for a different type with name

Hi Sebastian
I'll check that, but I know that I only have one version of
com.google.inject (I started with an xtext 2.3 distribution of Itemis,
but I also tried by starting from an eclipse-modeling-juno and
installing xtext from the composite site)... moreover I tried that with
a brand new domainmodel example (in a new workspace)...
you don't get this error by running this as a plugin junit test?
package org.eclipse.xtext.example.domainmodel.tests
import org.eclipse.xtext.example.domainmodel.DomainmodelUiInjectorProvider
import org.eclipse.xtext.junit4.InjectWith
import org.eclipse.xtext.junit4.XtextRunner
import org.junit.Test
import org.junit.runner.RunWith
@RunWith(typeof(XtextRunner))
@InjectWith(typeof(DomainmodelUiInjectorProvider))
class CompilerTest {
@Test
def void testGeneratedJava() {
}
}
