Apache Ivy
Encyclopedia
Apache Ivy is a transitive relation
dependency manager. It is a sub-project of the Apache Ant
project, with which Ivy works to resolve project dependencies. An external XML
file defines project dependencies and lists the resources necessary to build a project. Ivy then resolves and downloads resources from an artifact repository: either a private repository or one publicly available on the Internet
.
To some degree, it competes with Apache Maven
, which also manages dependencies. However, Maven is a complete build tool, Ivy focuses purely on managing transitive dependencies.

Transitive relation
In mathematics, a binary relation R over a set X is transitive if whenever an element a is related to an element b, and b is in turn related to an element c, then a is also related to c....

Apache Maven
Maven is a build automation and software comprehension tool. While primarily used for Java programming, it can also be used to build and manage projects written in C#, Ruby, Scala, and other languages. Maven serves a similar purpose to the Apache Ant tool, but it is based on different concepts and...

Features
- Managing project dependencies
- XML-driven declaration of project dependencies and jar repositories
- Automatic retrieval of transitive dependency definitions and resources
- Automatic integration to publicly-available artifact repositories
- Resolution of dependency closures
- Configurable project state definitions, which allow for multiple dependency-set definitions
- Publishing of artifacts into a local enterprise repository
