错误详细如下：

[INFO] ------------------------------------------------------------------------
[ERROR] Failed to execute goal com.spotify:docker-maven-plugin:0.4.13:build (default-cli) on project testt: Exception caught: pull access denied for jdk1.8, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

核心一句是这个

Failed to execute goal com.spotify:docker-maven-plugin:0.4.13:build (default-cli) on project testt: Exception caught: pull access denied for jdk1.8, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

百度查了一下，很多人说是要登录，实际上不是要登录，也不是仓库不存在，实际上是我的docker上没有jdk1.8的镜像文件，需要自己下一个，我是自己把jdk-8u221-linux-x64.tar.gz 通过DockerFile上传到上面去的，详情可以看https://blog.csdn.net/u014204541/article/details/102617063
dockerfile那块怎么传一个jdk文件进去，当然可以自己search jdk下载

解决jdk后，再执行构建就可以成功了
