Xtext - The type com.google.inject.Inject is not on the classpath

问题

I am using the following code in JvmModelInferrer.xtend to generate a Java class

@Inject extension JvmTypesBuilder

def dispatch void infer(Model element, IJvmDeclaredTypeAcceptor acceptor, boolean isPreIndexingPhase) {
    acceptor.accept(element.toClass(element.name)) [
        annotations += annotationRef(Inject);
    ]
}

When I try to run the whole project, I get the following error.

5226 [main] ERROR org.eclipse.xtext.xbase.jvmmodel.JvmTypesBuilder  - Error initializing JvmElement
java.lang.IllegalArgumentException: The type com.google.inject.Inject is not on the classpath.

I tried adding the corresponding dependency com.google.inject.source;bundle-version="3.0.0" to plugin.xml. Still I am getting the same error. How can we solve this issue?

回答1:

You have to make sure that Guice is on the classpath of the project, that contains your DSL file.
