Historically Nexus started as a repository manager supporting the Maven repository format. While it supports many other repository formats now, the Maven repository format is still the most common and well supported format for build and provisioning tools running on the JVM and beyond.
This chapter shows example configurations for using Nexus with a Maven and number of other tools. The setups take advantage of Nexus merging many repositories and exposing them via a repository group. Setting this up is documented in the chapter in addition to the configuration used by specific tools.
