Apache ANT

Apache Ant is a Java library and command-line tool whose mission is to drive processes described in build files as targets and extension points dependent upon each other. The main known usage of Ant is the build of 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.

Java should configured

1) mkdir -p apache-ant

2) [root@rhel6 webmin-1.791]# cd /usr/apache-ant/


Download tar file

http://olex.openlogic.com/packages/ant/1.9.2

[root@rhel6 apache-ant]# ls
apache-ant-1.9.6-bin.tar.gz
[root@rhel6 apache-ant]#


3) tar -xvzf apache-ant-1.9.6-bin.tar.gz


[root@rhel6 apache-ant]# ls
apache-ant-1.9.6  apache-ant-1.9.6-bin.tar.gz
[root@rhel6 apache-ant]#

[root@rhel6 apache-ant]# cd apache-ant-1.9.6
