Maven

• Needs internet first time to download
• Itself
• Dependencies
• Convention over configuration
• Standard lifecycle vs flexibility
• Build at command line or with built in Eclipse plugin m2e

@jeanneboyarsky

Maven

• Used by WPI in 2015 (now using gradle)
• pom.xml specifies what want done

@jeanneboyarsky

An Eclipse plugin

@jeanneboyarsky

Gradle

• Same internet/repository model as Maven
• Uses Groovy as language instead of XML
• Shorter ☺
