Building Docker file with Athena Driver

Hi everyone,

im building a custom version of metabase with some modified colors. The main problem is that i can't build a docker image within the Athena plugin.
Currently im addig these lines to the docker file, into the the "builder" stage

FROM metabase/metabase:v0.42.0
ADD --chown=80:2000 \


and for building the image i'm using the command

docker build . -t meta_palette_athena_v7/mb:1.0.0

but it doesn't work.
Actually i've built an image with the driver successfully , but i need to rebuilt a new one with a modified palette and nothing of this works anymore.
Thank you in advance for help
