配置发布插件
- central-publishing-maven-plugin：中央仓库发布插件
- maven-deploy-plugin maven：maven发布插件，任何仓库都需要这个插件
- maven-gpg-plugin：对发布的项目文件进行签名，中央仓库会对文件进行验签，GPG签名详见：https://central.sonatype.org/publish/requirements/gpg/

发布
- 运行发布命令
mvn deploy
- 等待maven central验证，如果发布状态不是published，那么就是发布失败，需要根据提示进行相应的更改
FAQ
- Javadocs must be provided but not found in entries：因为中央仓库没找到Javadoc文档，所以需要打包Javadoc文档，java 1.8打包doc文档时，会报异常，建议提升至java11打包
- Illegal reflective access by lombok.javac.apt.LombokProcessor xxx：java11打包Lombok时，需要查看Lombok和java版本是否支持
