3. From the Gradle website: http://www.gradle.org  Uses the Groovy scripting language to provide DSL  Build system for the Android operation system http://tools.android.com/tech-docs/new-build-system http://www.youtube.com/watch?v=LCJAgPkpmR0  Integrates with both ANT and Maven-based projects Gradle D. Maxwell, OpenXAL Workshop, March 2014, Slide 3

4. Gradle  Configuration using Groovy  Android, etc.  Multi-Project Support  Task Oriented (like Make)  Good Documentation  Open Source  Slower Comparison D. Maxwell, OpenXAL Workshop, March 2014, Slide 4 Maven  Configuration using XML  De-facto Standard w/ Java  Can be Done (but not Easily!)  Uses Plugins and Build Stages  Documentation  Open Source  Slow *Completely my Subjective Opinions
