Any reason to use this over Groovy ? Will Groovy has a few drawbacks, i found it much simpler and easier to use than scala.I personnally prefer a quick java over something that has to much features.Anybody tried both and can compare?
I've done quite a bit of groovy and have really enjoyed it. After years of doing java, and then years of ruby, and then trying to go back to java, I really struggled with rationalizing the move to myself given the immense amount of extra work java required to do anything productive. Groovy made the jump palatable, and in many ways I prefer groovy to ruby.
That said, I haven't written any code which is particularly performance sensitive yet. However, groovy now has @CompileStatic, so you can statically compile the perf sensitive bits. I'm sure that doesn't completely solve the problem, but it's an option.
I really do hope Kotlin succeeds thought. Having something in the middle of groovy and scala syntax-wise with no performance concerns and the great java integration groovy brings would be spectacular.
I recently wrote some scripts using Clojure to test some Java I'd written. It worked great, and I could use a macro to get rid of some duplication that functions couldn't.
I don't think Gradle will be using Groovy for too much longer. I looked at the source code for the recently released Gradle 2.0 and they'd replaced almost every Groovy source file with a Java version - only Groovy files specifically related to the DSL were left. And I suspect Gradle will soon open up its configuration as an API any language can use.
