不知道最近怎么回事，Docker镜像下载不下来，Maven依赖也下载不下来，手动下载一个jar文件安装到仓库。
mvn install:install-file -Dfile=jar包的路径 -DgroupId=gruopId中的内容 -DartifactId=actifactId的内容 -Dversion=version的内容 -Dpackaging=jar
如：
➜ ~ mvn install:install-file -Dfile=/Users/admin/Downloads/mybatis-plus-generator-3.3.2.jar -DgroupId=com.baomidou -DartifactId=mybatis-plus-generator -Dversion=3.3.2 -Dpackaging=jar
