The document outlines various Java build tools such as Ant, Maven, and Gradle, highlighting their features and updated usage in robotics programming. Ant is an older tool requiring no internet access, while Maven and Gradle offer modern advantages like dependency management and Groovy support, respectively. The presentation includes links to example build files and mentions Eclipse plugins for easier integration.

11. Maven
• Needs internet first time to download
• Itself
• Dependencies
• Convention over configuration
• Standard lifecycle vs flexibility
