uberjar artifacts do not get uploaded

[sco11morgan]

I'm trying to upload an uberjar to a maven repo using lein 2.3.2 and having problems. Ideally the normal jar and uberjar both would be built but only the uberjar would be uploaded. I've tried a few variations

:package {:artifacts [ {:build "uberjar" :extension "jar"}]}
Then only the normal jar is built and uploaded.

:package {:autobuild true :artifacts [ {:build "uberjar" :extension "jar"}]}
Then only the normal jar is built and uploaded.

:package {:artifacts [ {:build "uberjar" :extension "standalone.jar"}]}
Then both the normal jar and the uberjar are built, but only the normal jar is uploaded.

:package {:autobuild true :artifacts [ {:build "uberjar" :extension "standalone.jar"}]}
Then an attempt to upload is made but the artifact gets a ".standalone.jar" extension which fails on the maven repo side.

Had luck with:
:classifier "standalone" :extension "jar"
