I am trying to build image on offline environment using paketobuildpacks/builder:base and paketobuildpacks/run:base-cnb image. I am running a demo spring-boot project that I created via http://start.spring.io/
So this is the command I'm using to build the image
gradle clean build bootBuildImage
On my machine that has internet connection, everything works fine, and I'm able to build the image successfully. However, when I bring the same project over to my offline environment and tried to do the same, it throws me some error.
The only difference is that I need to configure this in my offline environment (build.gradle)
bootBuildImage {
builder = "myprivateartifactory/paketobuildpacks/builder:base",
runImage = "myprivateartifactory/paketobuildpacks/run:base-cnb"
}
The following is ran with --debug enabled - gradle clean build bootBuildImage --debug

What am I doing wrong? If more information is required, please let me know
Thanks!
See spring-boot#24641 for more discussion. In short, the reason for the error mentioned above was that the wrong image was used.
