Spring boot 2.5.x layer does not exist error

[thiaguten]

Hi,

I'm using this plugin to create a Dockerfile with correct layers for my springboot project, but I'm facing a strange error in my CI during docker build process and I have no clue what is wrong so I open this issue for some help.

Snippet of the error:

I'm using SpringBoot 2.5.6 with Java 11 and Gradle 7.2

The complete CI Build image log, Dockerfile and build.gradle are attached .

Thanks for all the help.

I think this error is related with docker server engine version running on Azure because locally on my machine with docker version 20.10.8 the build command works perfectly and the image was created.

$ cd build/docker $ docker build -t myorg/demo:latest .

So after searching about this error I found this issue: COPY fail in multistage build: layer does not exist

The workaround was to put RUN true between the ADD commands in my Dockerfile (attached)

Dockerfile.txt

So if anyone is facing this problem, here is a possible solution. I don't think it's a pretty solution though
