java - Xtext - com.google.inject.Inject 类型不在类路径上

Question

我在 JvmModelInferrer.xtend 中使用以下代码来生成 Java 类

@Inject extension JvmTypesBuilder

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

当我尝试运行整个项目时，出现以下错误。

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.
    at org.eclipse.xtext.xbase.jvmmodel.JvmAnnotationReferenceBuilder.annotationRef(JvmAnnotationReferenceBuilder.java:83)
    at org.eclipse.xtext.xbase.jvmmodel.JvmAnnotationReferenceBuilder.annotationRef(JvmAnnotationReferenceBuilder.java:60)

    at org.eclipse.xtext.xbase.jvmmodel.JvmTypesBuilder.toField(JvmTypesBuilder.java:588)

我尝试将相应的依赖项com.google.inject.source;bundle-version="3.0.0"添加到plugin.xml。我仍然遇到同样的错误。我们该如何解决这个问题？

您必须确保 Guice 位于包含 DSL 文件的项目的类路径中。
