由于 spring-cloud-starter-alibaba-nacos-config模块在2021.x 分支缺少 jakarta.annotation-api 依赖包导致 (以前该依赖是由其他模块传递依赖进来的, 可能由于部分模块版本号的升级, 其他模块已经不再依赖 jakarta.annotation-api 这个包)

2.2.x 分支是通过spring-boot-starter包传递依赖进来的, 2021.x分支在之前的一个提交已经移除掉了spring-boot-starter包

可以考虑直接在 spring-cloud-starter-alibaba-nacos-config模块下添加以下依赖:

    <dependency>
      <groupId>jakarta.annotation</groupId>
      <artifactId>jakarta.annotation-api</artifactId>
    </dependency>
