Apache Ivy


Apache Ivy is a transitive package 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, whereas Ivy focuses purely on managing transitive dependencies.
Newer build tools and continuous integration servers regularly support or include Ivy:
first created Ivy in September, 2004, with Xavier Hanin serving as the principal architect and developer of the project. Jayasoft moved hosting of Ivy to Apache Incubator in October 2006. Since then, the project has undergone package renaming to reflect its association with the Apache Software Foundation. Package names prefixes of the form fr.jayasoft.ivy have become org.apache.ivy prefixes.
Ivy graduated from the Apache Incubator in October, 2007. As of 2009 it functions as a sub-project of Apache Ant.
