java - "org.reflections.Reflections - could not get type for name"当对包含 groovy 类的包使用反射时

Question

我有几个 groovy 类，其中包含用 @Issue 注释的 spock 测试。我正在尝试使用反射来获取所有这些方法。我收到以下异常>>

这是我到目前为止的代码:

Set<Method> TestMethodsList = new ReflectionsLibrary("package name here").getTestMethods()

我尝试了几种方法来实例化反射实例

1-

reflections = new Reflections(new ConfigurationBuilder()
                 .setScanners(new SubTypesScanner(false /* don't exclude Object.class */), new ResourcesScanner(),new MemberUsageScanner(), new MethodAnnotationsScanner(), new MethodParameterScanner())
                 .setUrls(ClasspathHelper.forClassLoader(classLoadersList.toArray(new ClassLoader[0])))
                 .addClassLoader(this.getClass().getClassLoader())
                 .filterInputsBy(new FilterBuilder().include(FilterBuilder.prefix(packageName))))

2-

reflections = new Reflections(new ConfigurationBuilder().setUrls(ClasspathHelper.forPackage(packageName))
                .addScanners(new MemberUsageScanner(), new MethodAnnotationsScanner(), new MethodParameterScanner()))

然后我打电话

     Set<Method> getTestMethods() {

         return reflections.getMethodsAnnotatedWith(Issue.class)

    }

也许在处理 groovy 时还有另一种使用反射的方法。顺便说一句，这段代码适用于 java 类。

有什么想法吗？

谢谢

Answer 1

嗯，我想我找到了我的问题。我的类(class)不知何故以“。”结束。在最后。因此类加载器找不到它们。没有额外的点的测试是有效的，所以我只需要弄清楚点到底添加在哪里。
