This happens when building a dry-run release per the instructions here: https://calcite.apache.org/avatica/docs/howto.html#making-a-release-for-calcite-committers
If we patch the dockerfile to include `-SNAPSHOT`, maven fails due to there being modified files in the working tree.
If we do not patch the docker file, maven fails because it expects AVATICA_VERSION to be $VERSION-SNAPSHOT rather than $VERSION.
A solution would be to exclude the docker file from being checked for modifications in pom.xml. Is this a reasonable approach?
