Which is the best build tool for Android projects, Ant, Maven or Gradle?

Facebook's Buck is actually much faster and better IMO. Buck was derived from Google's Blaze Java build tool. http://blog.ltgt.net/in-quest-of-the-ultimate-build-tool/

Its always a puzzle which build tool to choose maven, gradle or both (maven and gradle). Sometime its first time project setup or could be migration from existing tool but it always a debate to choose one of the existing one. There have been lot of talks and discussion on Gradle, maven (and/or Gradle vs maven). There are Buzz around that Android/google adopted Gradle as its standard build tools. Here, i would like to explore the possibilities of adopting Gradle or maven (Or Both), Intentionally i am keeping ant+ivy out of this talk. Lets take a look in details on why android adopted gradle Key points for the google to go ahead with gradle for their android development are Create multiple APKs for your app with different features using the same project.(create several variants of an application) Reuse code and resources. Customize, configure, and extend the build process. Customized integration with their own IDE Android Studio. Single build tools to support multiple languages. They had some special requirements for their diverse eco system, they worked with gradleware development team to include customized feature for the android application. They even have customized IDE for android Developers build around gradle. If you really want to compare maven and gradle on the basis of their features and your user case for adoption in to your project. Have a look at this. @http://www.scmtechblog.net/2015/03/gradle-or-maven-dilemma.html Above article will give you more detail about Gradle build system and checklist of adoption compare to Maven.
