我能够在eclipse中成功执行测试用例，但在maven构建期间，我收到以下错误。

有人可以告诉我为什么会出现此错误以及如何解决此问题吗？

Answer 1

更新您的依赖项应解决此问题 -

<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>3.8.1</version>
</dependency>

到

<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.12</version>
</dependency>

正如Javadoc for RunListener中所述，该类是在版本4.0中引入的。另外，请确保传递不同版本的相同工件无法解决。
