What is Ant-Contrib Tasks?
The Ant-Contrib project provides a collection of tasks and types that extend Ant to work as a scripting language as well as a build tool.
Many developers want more from Ant than the ability to define dependencies. Ant-Contrib adds extra functionality to let Ant act more like a programming lanuage. Most tasks require Ant 1.5 or higher to work properly.
“Ant-Contrib Tasks” is an “independent third party” library of useful additional procedural and utility ApacheAnt Tasks.
Pre-Requisite:
First you must install Apache Ant itself, most of the Ant-Contrib tasks require Ant 1.5 or higher to work properly. You can download Ant from Apache.

“Ant-Contrib Tasks” is also TWO independent ant task libraries:
- “cpptasks for Apache Ant” – “The cc task can compile various source languages and produce executables, shared libraries (aka DLL’s) and static libraries. Compiler adaptors are currently available for C/C++, FORTRAN, MIDL and Windows Resource compilers.”
- Project home page: http://ant-contrib.sourceforge.net/cpptasks/index.html
- ‘Ant-Contrib Other Tasks’
- Documentation of ant tasks: http://ant-contrib.sourceforge.net/tasks/tasks/index.html
- Download: Must fetch from Subversion and build yourself. See instructions at: https://sourceforge.net/svn/?group_id=36177
Installation
See the cc tasks for installation instructions for cpptasks. To install ant-contrib:
- Copy ant-contrib-0.3.jar to the lib directory of your Ant installation. If you want to use one of the tasks in your own project, add the lines
2. <taskdef resource="net/sf/antcontrib/antcontrib.properties"/>
to your build file.
- Keep ant-contrib-0.3.jar in a separate location. You now have to tell Ant explicitly where to find it (say in /usr/share/java/lib):
4. <taskdef resource="net/sf/antcontrib/antcontrib.properties">
5. <classpath>
6. <pathelement location="/usr/share/java/lib/ant-contrib-0.3.jar"/>
7. </classpath>
8. </taskdef>

A practical challenge with Ant-Contrib often appears when build scripts continue to expand over time. While adding extra capabilities can help automate complex tasks, too much logic inside build files can make them difficult for new team members to understand and maintain. In larger environments, it is important to keep automation workflows organized, reduce unnecessary complexity, and ensure that custom build dependencies are managed consistently across local and CI environments. Without proper version control and documentation, small differences in tooling setups can create difficult-to-trace build issues during releases.
