java - 使用 spring 版本 2.5.7 的 Spring Boot 无法使用 jdk 1.8 重新打包

Question

运行 maven 包目标时

mvn clean package

构建抛出错误:

goal org.springframework.boot:spring-boot-maven-plugin:3.0.0-M1:repackage failed: Unable to load the mojo 'repackage' in the plugin 'org.springframework.boot:spring-boot-maven-plugin:3.0.0-M1' due to an API incompatibility: org.codehaus.plexus.component.repository.exception.ComponentLookupException: org/springframework/boot/maven/RepackageMojo has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 52.0

我的 JAVA_HOME 指向 jdk1.8.0_73

如何让 spring-boot-maven-plugin 以重新打包的目标运行？

以下是我的模块中的 maven 构建配置。

你 pom.xml 中使用的“spring-boot-maven-plugin”插件的版本是 3.0.0-M1，只能用于 Java 17 或更高版本。切换到 2.5.7，如果它真的是你想用于 spring boot 项目的版本。
