对包含groovy类的包使用反射时，"org.reflections.Reflections -无法获取名称的类型“

Question

我有几个包含用@Issue注释的spock测试的groovy类。我正在尝试使用反射来获取所有这些方法。我在>>下面得到了异常

下面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()))

然后我会打电话给

     Set<Method> getTestMethods() {

         return reflections.getMethodsAnnotatedWith(Issue.class)

    }

在处理groovy时，也许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

我想我找到我的问题了。不知何故，我的课程以".“结尾。在最后。因此，类加载器找不到它们。没有额外的点就可以测试了，所以我只需要弄清楚这个点到底是在哪里被添加的。
