The Debian rules files for HBase and Whirr aren't ever invoking Maven - i.e., they're never actually building the jars, etc. The RPMs are, but not the Debians. I'm assuming this is because of historic problems with running Maven from within a Debian build, thanks to running as fakeroot, etc. We have a workaround for this - see Oozie's rules file for the approach. This shouldn't be hitting any non-Maven projects, so everything else currently up there should be fine. I'll have a patch up shortly.
