Junit测试在Eclipse中工作，但在通过Ant运行时失败

TestRunner.class

java.lang.ClassNotFoundException: TestRunner.class

当我在eclipse中运行它时，Junit测试工作，但是当我通过ant（通过eclipse或终端运行）运行它们时失败;他们每个都抛出以下异常：

        for(int i = 2; i<11;i++){
            Element category = doc.getElementById("w"+i); // select section with id = w2 , w3, w4 ...
            if(!category.select("div.b-module-carousel__title").isEmpty()){
                System.out.println(category.select("div.b-module-carousel__title").text()); // the title of the section is either here
            }
            else{

            }
            Elements items = category.select("li");

                System.out.println(  e.select("div.b-block-info-container__title").text()
