DownloadIndexer

SpongeDownloads

SpongeDownloads is the download indexer for the Sponge project. It accepts uploaded builds as a standard Maven repository, indexes them and finally uploads it to the real Maven repository. It provides a REST API that is primarily used by Sponge's download page, however it can be also used by other projects (e.g. hosting providers) to provide automated installation of Sponge builds.
