Since version 3.2.3, "clean install deploy" will deploy javadoc and source jars twice, which fails on our deployment policy. Release versions can be deployed only once.
"clean deploy" fixes the issue, "clean install deploy" triggers it. "clean install" alone is okay, too. It installs javadoc and source jars only once.
Please see attached a minimal example project, it's created through archetype. I've added javadoc and install plugin, as well as distributionManagement to deploy into "test" directory of user's home.
