Spring 2.x升级至Spring Boot 3.2.0时出现Gradle构建依赖解析错误

按OpenRewrite官方文档升级Spring Boot到3.2版本，添加对应插件与依赖后启动服务，遭遇Gradle构建失败。核心错误为无法解析org.springframework.boot:spring-boot-gradle-plugin:3.2.5，原因是项目使用Java 11，但该插件要求Java 17，同时存在org.gradle.plugin.api-version属性匹配问题（当前值为7.6.4）。

BUILD FAILED in 282ms

• 升级Java到17：Spring Boot 3.2及配套Gradle插件最低要求Java 17，这是符合官方规范的最优解。
• 降级Spring Boot版本：若暂时无法升级Java，可降级到Spring Boot 3.1.x系列（支持Java 11），同步调整Gradle插件版本。
• 升级Gradle版本：Spring Boot 3.2要求Gradle 8.0及以上，当前使用的7.6.4不兼容。若选择升级Java到17，需同时将Gradle升级到8.x版本。
