java - 无法让 org.reflections.Reflections 工作，NoClassDefFoundError

Question

我不确定自己在反射方面做错了什么。所以这是一个例子，我有一个包 testreflections.test，里面有类 Main 和 TestClass。

主类:

public class Main {

    public static void main(String[] args) {
        Reflections reflections = new Reflections("testreflections.test");
        //Reflections reflections = new Reflections("testreflections.test.TestClass");//I also tried this
        Set<Method> resources =
            reflections.getMethodsAnnotatedWith(org.junit.Test.class);

        System.out.println(resources.size());

         for (Method set : resources) {
             System.out.println(set.toString());
         }
    }
}

测试类:

public class TestClass {

    @Test
    public void testMethod() {
        System.out.println("This is a test");
    }
}

现在，我只是应该获取所有带有 junit Test 注释的方法(这只是 1)。这应该将一个添加到集合中，并为它打印出适当的信息。然而，eclipse 吐出这个错误:

事实证明我只需要添加 Javaassist到类路径。
