Bamboo has built-in support for various builder tasks, including Ant and Maven (and can be extended with additional ones via add-ons available on the Atlassian Marketplace):

A builder task allows you to connect your Bamboo plan (or job) to a build tool such as Ant, Maven or MSBuild. The build tool uses its existing configuration when the plan (or job) is built.

Please refer to the dedicated Ant and Maven task documentation for details.
