Just upgrades to the recently released 5.0.0-beta3.

These beta suffixes don't work with the versioning in the plugin release. We'd either need to fix that first, or stick with snapshots until the full 5.0.0 release.

@jimschubert Got it. I just saw #5 as well. If the bintray repo supports snapshots (looks like it does?) I'm totally happy to work with snapshots. Unfortunately the versioning in this repo is static so they're not getting published on merges.

I'm not sure if you're open to it, but I'd be happy to set up sbt-dynver for versioning instead (#25), which would handle snapshots and versioning a little more automatically - you'd just need to create tagged releases for the repo on Github to line up with dependency updates.

This also explains why I wasn't able to write a scripted test for my last PR adding the new SBT key - the version being submitted to the scripted test was the incorrect static version from master rather than the snapshot being built. I can submit a PR for that too now.
