我有一台jenkins机器，我想用它来构建testng测试，他将通过我的存储库。这一切都有效，但是当他开始运行我的测试时，我得到了这个错误。

这是我的pom文件，但在这里我真的在试图解决如何运行它。所以我不知道发生了什么事情。

有人可以说我做错了什么，或者我需要编辑什么来实现这个目标？

Answer 1

发生异常（java.lang.UnsupportedClassVersionError）是由于您用于编译代码的Java版本与您用于执行代码的Java版本之间不兼容导致的。

显然，你的代码中使用Java 8（版本为52.0）编制，现在你想使用Java 7

检查运行它，如果你詹金斯的Java版本是一样的机器，其中的Java版本你编译你的代码。
