Julian> The Release Policy [1] states that for a (compiled) artifact the source code has to be released alongside.
maven-wrapper.jar has nothing to do with Calcite's source codes, so maven-wrapper.jar is not "a compiled version of the source", so [1] does not apply here. It is the very same thing as "binary font file". I don't see why the policy would allow *.ttf and forbid *.jar at the same time. It is basically the same thing as long as the binary comes from somewhere else. Of course, we should not include calcite.jar into source distribution. However, maven-wrapper.jar is not something that is produced by Calcite's sources, so it should be fine. Vladimir
