The sbt organization is available for use by any sbt plugin. Developers who contribute their plugins into the community organization will still retain control over their repository and its access. The goal of the sbt organization is to organize sbt software into one central location.
A side benefit to using the sbt organization for projects is that you can use gh-pages to host websites under the http://scala-sbt.org domain.
Lightbend has provided a freely available Ivy Repository for sbt projects to use. This Ivy repository is mirrored from the freely available Bintray service. If you’d like to submit your plugin, please follow these instructions: Bintray For Plugins.
See Cross Build Plugins.
Please feel free to submit a pull request that adds your plugin to the list.
