jcenter is the public repository hosted at bintray that is free to use for open source library publishers. There are many good reasons to use jcenter over Maven Central. Here are some of the major ones:
- jcenter delivers library through CDN which means improvements in CI and developer builds.
- jcenter is the largest Java Repository on earth. This means that whatever is available on Maven Central is available on jcenter as well.
- It is incredibly easy to upload your own library to bintray. No need to sign them or do any complex things like you have to on Maven Central.
- If you want to upload your library to Maven Central you could do it easily with a single click on the bintray site.
