It is a me too language from Eclipse foundation without any clear roadmap why anyone in the industry would care to use it given the more mature JVM languages, specially given its dependency to Eclipse and generation of Java code instead of bytecode.

Xtext, the Eclipse/JVM language development toolkit behind Xtend, is in many ways more interesting than Xtend itself. In fact (I may be wrong) but Xtend was really done as an Xtext example/test/advertisement.

I have used Xtend a little (not in production) and it was interesting when first introduced. I suspect Java 8 will make it redundant.

My feelings as well. I just looked into it as a possible language for Android development given the stagnation on Java compliance on the platform, but Kotlin looks much better suited for it given Google's investment into InteliJ.

A search on Github for Xtend classes reveals 10,502 results: https://github.com/search?q=class+extension%3Axtend&type=Cod...

This beats Ceylon by factor two (4,189 results) and is close to Kotlin (12,233 result).
