Spring Boot 项目完成后，准备部署到生产环境服务器。如何打包呢？
方式一：命令行
mvn clean
mvn package
方式二：IDEA IDE
IDEA 右侧有个 Maven 菜单，点开之后，双击 Lifecyle 中的 clean 和 package.

50M 的 jar 包 。。。
为何需要执行 mvn clean
For example: If you rename a class, the previous compiled version will remain in target/classes until you run clean. This maybe completely harmless, but it could cause issues if it is autodetected by classpath scanning and the like.
简言之就是清理 target 目录下的 class 文件缓存。防止因重命名造成的问题。
如何修改版本号
修改 pom.xml 中的 version。
