使用maven打包报错如下：
[ERROR] Plugin org.springframework.boot:spring-boot-maven-plugin:1.5.4.RELEASE or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.springframework.boot:spring-boot-maven-plugin:jar:1.5.4.RELEASE: Could not transfer artifact org.springframework.boot:spring-boot-maven-plugin:pom:1.5.4.RELEASE from/to central (https://repo.maven.apache.org/maven2): Connect to repo.maven.apache.org:443 [repo.maven.apache.org/151.101.196.215] failed: Connection timed out: connect -> [Help 1]

解决方法：
打开自己的maven的setting配置文件
搜索mirrors关键字，加入mirror镜像节点
<mirror>
<id>osc</id>
<mirrorOf>*</mirrorOf>
<url>http://maven.oschina.net/content/groups/public/</url>
</mirror>
更新maven依赖
然后 重新编译
即可成功！！
如果依旧没有成功，把刚刚添加的上面的 删除掉，重新更新maven依赖，然后重新打包，我这里就成功打包了！！
