bad class ：类文件版本错误 55.0，应该是 52.0 Maven Eclipse

Question

错误的类错误：我的系统没有 Java 11，它仍然指向 Java 8（在环境变量、Eclipse 构建路径、Eclipse Java 编译器级别）仍然存在编译错误类文件的版本错误 55.0，应该是 52.0 .

最近chrome升级到122版本，后来我们不得不更新selenium到4.17.0和web driver到5.6.3以使其兼容chrome 122版本。

错误：

java.lang.UnsupportedClassVersionError: testrunners/MyTestRunner has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

Answer 1

这是版本控制错误，因为Java 8，如果没有升级选项-降级其他依赖项；顺便说一句，即使您的系统在路径中有“硬编码”jre8，您甚至无法仅为您的用户更新它，您仍然可以从 Oracle 下载所需的 JDK 并在您的项目的 IDE 设置中选择它
