无法在脱机环境下使用gradle bootBuildImage构建镜像

Question

我正在尝试使用paketobuildpacks/builder:base和paketobuildpacks/run:base-cnb镜像在离线环境中构建镜像。我运行的是我通过http://start.spring.io/创建的demo spring-boot project

这就是我用来构建镜像的命令

gradle clean build bootBuildImage

在我的有互联网连接的机器上，一切工作正常，我能够成功地构建镜像。然而，当我把同样的项目带到我的离线环境中，并试图做同样的事情时，它抛出了一些错误。

唯一的区别是我需要在我的离线环境(build.gradle)中配置它。

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

在启用了--debug的情况下运行以下命令- gradle clean build bootBuildImage --debug
