Apache Ant is a Java™ library tool for automating the build process. You can use Ant tasks provided by the Liberty profile to manage the server and applications.
<project .... xmlns:wlp="antlib:com.ibm.websphere.wlp.ant">
...
</project>
The namespace can be any string, provided you avoid name conflicts. After that, you must use the namespace as a prefix of the Ant tasks for the Liberty profile. For example, you must use wlp:server when calling the server task.
You can create build scripts that use these Ant tasks to package, install, and test your application on the Liberty profile.
