This. Like most folks here, I like learning new things. I learned Ant a long time ago, and then Maven (to GP's point, learning Maven was NOT trivial). When I started through the Gradle docs and realized that it's a DSL written in Groovy, I had to open a new tab in my browser and start learning Groovy. Now I'm thinking to myself: "Great. In order to really grok Android Studio, I need to learn Gradle. To grok Gradle, I need to learn Groovy." As I mentioned in a previous comment, with all there is in this life to learn, I just can't bring myself to learn Gradle when I already know 2 other Java build tools :)
