Question

我正在开发一种DSL，它可以重用另一种DSL中定义的类型。基本上我有两个文件扩展名，让我们说.A和.B，一些实体在.A中声明，我需要在.B中访问它们。我使用importURI只能访问我需要的引用.A。

代码完成工作完美，它为我提供了.A中声明的实体，但问题是我看到错误消息说无法解析引用。

我已完成与此帖xtext importURI external file中建议相同的事情，以下是我的工作流程片段：

         // Java API to access grammar elements (required by several other fragments)
            fragment = grammarAccess.GrammarAccessFragment auto-inject {}

            // generates Java API for the generated EPackages
            fragment = ecore.EMFGeneratorFragment auto-inject {}

            // the old serialization component
            // fragment = parseTreeConstructor.ParseTreeConstructorFragment auto-inject {}    

            // serializer 2.0
            fragment = serializer.SerializerFragment auto-inject {
                generateStub = false
            }

            // a custom ResourceFactory for use with EMF
            fragment = resourceFactory.ResourceFactoryFragment auto-inject {}

            // The antlr parser generator fragment.
            fragment = parser.antlr.XtextAntlrGeneratorFragment auto-inject {
            //  options = {
            //      backtrack = true
            //  }
            }

            // Xtend-based API for validation
            fragment = validation.ValidatorFragment auto-inject {
                composedCheck = "org.eclipse.xtext.validation.ImportUriValidator"
                composedCheck = "org.eclipse.xtext.validation.NamesAreUniqueValidator"
            }

            // old scoping and exporting API
            fragment = scoping.ImportURIScopingFragment auto-inject {}
            // fragment = exporting.SimpleNamesFragment auto-inject {}

            // scoping and exporting API
            fragment = scoping.ImportNamespacesScopingFragment auto-inject {}
            fragment = exporting.QualifiedNamesFragment auto-inject {}
            //fragment = builder.BuilderIntegrationFragment auto-inject {}

            // generator API
            //fragment = generator.GeneratorFragment auto-inject {}

            // formatter API
            //fragment = formatting.FormatterFragment auto-inject {}

            // labeling API
            //fragment = labeling.LabelProviderFragment auto-inject {}

            // outline API
            //fragment = outline.OutlineTreeProviderFragment auto-inject {}
            //fragment = outline.QuickOutlineFragment auto-inject {}

            // quickfix API
            fragment = quickfix.QuickfixProviderFragment auto-inject {}

            // content assist API
            fragment = contentAssist.ContentAssistFragment auto-inject {}

            // generates a more lightweight Antlr parser and lexer tailored for content assist
            fragment = parser.antlr.XtextAntlrUiGeneratorFragment auto-inject {}

            // generates junit test support classes into Generator#pathTestProject
            //fragment = junit.Junit4Fragment auto-inject {}

            // rename refactoring
            //fragment = refactoring.RefactorElementNameFragment auto-inject {}

            // provides the necessary bindings for java types integration
            //fragment = types.TypesGeneratorFragment auto-inject {}

            // generates the required bindings only if the grammar inherits from Xbase
            //fragment = xbase.XbaseGeneratorFragment auto-inject {}

            // provides a preference page for template proposals
            //fragment = templates.CodetemplatesGeneratorFragment auto-inject {}

            // provides a compare view
            //fragment = compare.CompareFragment auto-inject {}

感谢Christian，通过重新生成默认的.mwe2并对这两个片段进行评论来实现它的工作



    //generates the required bindings only if the grammar inherits from Xbase
    //fragment = xbase.XbaseGeneratorFragment auto-inject {}

    //provides a preference page for template proposals
    //fragment = templates.CodetemplatesGeneratorFragment auto-inject {}

xtext importURI引用无法解析
