Travis CI上JUnit测试用例的InitializationError

Question

我试图弄清楚Travis CI，以便为Selenium项目运行我的JUnit测试。 从我的机器（在IntelliJ IDEA中）运行它们时，单元测试工作。

由于测试类似乎什么都没有遗漏，我想知道为什么测试可以在我的机器上完美运行，但是在Travis CI上却失败了。 我的设置有问题吗？

.travis.yml文件：

language: java

jdk:
  - oraclejdk8

script: ant test


#before_install:
# - cd java

构建文件：

我从Travis CI获得的构建输出失败：

看来我已经将TestNg与JUnit混淆了。 看一下我误用的输入：

import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;
