Can this be moved out from the switch case here? Seems they would be removed regardless of the case, or can we use a local label to replace the the switch case to avoid repeated commands? sth like:

...
rm -rf /libs/coordinator/lib/unpacked-blob-compressor/linux-$MACHINE_TYPE/; \
...
rm -rf /libs/coordinator/lib/unpacked-blob-shnarf-calculator/linux-$MACHINE_TYPE/;

[jonesho]

I dun think we even need these apt-get related commands here, right?

[jpnovais]

@jonesho IIRC from our last our meeting with @julien-marchand we agreed on not having a builder image because the step commands bellow in RUN can be executed in the host machine.?

What is the motivation and value of having a builder image?

[jonesho]

@jpnovais Yes, but as mentioned above, the jar command was not available in JRE image, and hence we need to use JDK image here to use the jar command to extract and recreate the JAR archive based on the machine type (from uname -m). I was thinking about moving this "extract and recreate JAR" step to pipeline job but then we'd need separate "extract + build" jobs for arm64 and amd64 image respectively, which would take up more pipeline resources and runtime imo, and complicate the build process. Welcome for any better approach :)
