Hi,
I am a new java developer and I am using Gradle as build tool. Gradle script is written in Groovy language…should I consider learning Groovy to get a better understanding of Gradle?
There are several books referenced on http://www.gradle.org/books page. If you are looking for a complete reference the problem is that printed books are outdated quickly for a continually evolved project like Gradle. There is a great user guide http://www.gradle.org/docs/current/userguide/userguide.html though.
Learning Groovy is not necessary but it can help you to become well-grounded Java developer in this world of polyglot programming. Similar concepts can be found in other languages too.
