What is CentOS?
CentOS Linux is a free and open source operating system that is functionally compatible with its upstream source, Red Hat Enterprise Linux (RHEL). CentOS conforms fully with the upstream vendor's redistribution policy and aims to be 100% binary compatible. It aims to provide enterprise-class capabilities on community-supported infrastructure.
What is Nexus?
The Nexus repository is a repository that facilitates the discovery, access and installation of public artifacts. It supports open source dependencies and references them in Maven-compatible package declarations. The most common use is to resolve a target dependency by hashing a file with a specified MD5 sum and using Nexus to look up the artifact in its local cache or available repositories . It is also possible to combine Maven (and other) metadata with an artifact before publication.
