离线环境下无法使用 gradle bootBuildImage 构建镜像

Question

我正在尝试使用paketobuildpacks/builder:base 和paketobuildpacks/run:base-cnb 图像在离线环境中构建图像。我正在运行我通过http://start.spring.io/ 创建的demo spring-boot project

所以这是我用来构建图像的命令

gradle clean build bootBuildImage

在我的有互联网连接的机器上，一切正常，并且我能够成功构建映像。但是，当我将同一个项目带到我的离线环境并尝试做同样的事情时，它会引发一些错误。

唯一的区别是我需要在我的离线环境（build.gradle）中配置这个

bootBuildImage {
  builder = "myprivateartifactory/paketobuildpacks/builder:base",
  runImage = "myprivateartifactory/paketobuildpacks/run:base-cnb"
}

以下是在启用 --debug 的情况下运行的 - gradle clean build bootBuildImage --debug
