如何在Xtext中获取输入文件的名称

@Override
public void configureResourceSet(ResourceSet resourceSet) {
    super.configureResourceSet(resourceSet);
    resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("yourdsl", new XtextResourceFactory());
    resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("xmi", new XMIResourceFactoryImpl() {
        @Override
        public Resource createResource(URI uri) {
            XMIResource resource = (XMIResource) super.createResource(uri);
            resource.setIntrinsicIDToEObjectMap(new HashMap<String, EObject>());
            return resource;
        }
    });
    resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("ecore", new EcoreResourceFactoryImpl());
    resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("genmodel", new GenModelResourceFactoryImpl());
    resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("xcore", new XcoreResourceFactoryImpl());
    resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("xtend", new XtendResourceFactoryImpl());
    resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("java", new JavaResourceFactoryImpl());
    resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("txt", new TextResourceFactoryImpl());
}

@Override
public void configureRuntimeEcorePackage(Binder binder) {
    super.configureRuntimeEcorePackage(binder);
    binder.bind(EPackage.Registry.class).toInstance(EPackage.Registry.INSTANCE);
}

override void doGenerate(Resource resource, IFileSystemAccess2 fsa, IGeneratorContext context) {
    val inputFile = resource.URI.trimFileExtension.lastSegment
    // 使用inputFile变量来获取输入文件的名称
    // 进行后续的处理
}
