What is included in JCenter repository in Gradle?
As mentioned in https://bintray.com/bintray/jcenter:
JCenter is the place to find and share popular Apache Maven packages for use by Maven, Gradle, Ivy, SBT, etc. For the most comprehensive collection of artifacts, point your Maven at: http://jcenter.bintray.com Want to distribute your own packages through JCenter? You can link your package by clicking the "Include My Package" button. And if you're into legacy, you can even synchronize your packages directly to Maven Central.
Also I find a good compare at https://www.jfrog.com/knowledge-base/why-should-i-use-jcenter-over-maven-central/ (unfortunately the link seems dead but some useful hints are here):
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.
- Friendly-UI If you want to upload your library to Maven Central you could do it easily with a single click on the bintray site.
jcenter() is similar to mavenCentral(). Have a look at https://bintray.com/bintray/jcenter for more details. The JCenter guys claim that they have a better performance than Maven Central.
