Apache Ant is a Java library and command-line tool that drives processes described in build files as targets and extension points dependent upon each other. Ant is primarily used to build Java applications. Ant supplies a number of built-in tasks allowing to compile, assemble, test and run Java applications. Ant can also be used effectively to build non Java applications, for instance C or C++ applications. More generally, Ant can be used to pilot any type of process which can be described in terms of targets and tasks.

Ant is written in Java. Users of Ant can develop their own “antlibs” containing Ant tasks and types, and are offered a large number of ready-made commercial or open-source “antlibs”.

Ant is extremely flexible and does not impose coding conventions or directory layouts to the Java projects which adopt it as a build tool. Software development projects looking for a solution combining build tool and dependency management can use Ant in combination with Apache.
