Maven, Ant, and Gradle are very wide spread Java build systems. Unfortunately it is not trivial to distribute source based ebuilds which require Maven. (see Gentoo Java Packing Policy).

As of 2019-06-23, Gentoo only has a binary ebuild for Maven in the Gentoo ebuild repository. However is still not available
