【JAVA程序CI报错】this version of the Java Runtime only recognizes class file versions up to 52.0

【JAVA程序CI报错】this version of the Java Runtime only recognizes class file versions up to 52.0

原因

由于maven官方在20221124174919升级了spring-boot-maven-plugin插件到3.0版本，而最新的3.0.0版本不被jdk8支持，导致编译打包报错。

报错异常

解决方案

在引入spring-boot-maven-plugin插件的时候，需要指定插件的版本，在项目的l添加以下配置：

<plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><version>2.7.5</version>  # 版本<configuration><mainClass&st.WebApplication</mainClass>   # 启动类的位置</configuration><executions><execution><goals><goal>repackage</goal></goals></execution></executions>
</plugin>
