What is Debian?
Debian is a free operating system ( OS ) for your computer. An operating system is the set of basic programs and utilities that make your computer run. Debian uses the Linux kernel (the core of an OS) along with thousands of software packages (also called 'packages') that are each distributed in a separate file. The packages contain the program code that does all the work, and are connected to each other in what is called a package dependency hierarchy . Each package depends on some smaller package or packages, which in turn depend on even smaller packages, and so on.
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.
