我使用的Maven版本为3.3.9

解决方法：

在config seting.xml中修改jdk版本，将其改为自己电脑上面装的JDK版本，下面以JDK1.8为例。

<profile>
      <id>jdk-1.8</id>

      <activation>
        <jdk>1.8</jdk>
      </activation>

      <repositories>
        <repository>
          <id>jdk14</id>
          <name>Repository for JDK 1.8 builds</name>
          <url>http://www.myhost.com/maven/jdk14</url>
          <layout>default</layout>
          <snapshotPolicy>always</snapshotPolicy>
        </repository>
      </repositories>
    </profile>

最后成功解决了项目部署的问题：
