直接使用阿里云镜像仓库打包没问题，替换为私服镜像仓库后报错：
就是pom.xml中的plugin报错
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.5</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
网上找了半天说这个指定的jdk版本的问题，查了一下版本没问题都是1.8
报错内容：
