Are you referring to continuous integration? Cont delivery? Just stacks? If you're referring to some platforms..
CircleCI http://circleci.com as a continuous integration and deployment platform - they automate the build, test, and deploy process.
LaunchDarkly http://launchdarkly.com if you're looking to feature flag your builds and automate rollouts.
Gradle http://gradle.org is an open source build automation system that builds upon the concepts of Apache Ant and Apache Maven and introduces a Groovy-based domain-specific language (DSL) instead of the XML form used by Apache Maven of declaring the project configuration.
You can use Polyglot-Maven [1] with Maven if you want to use a programming language syntax atop the XML. Polyglot-Maven enables not only Groovy, but also Ruby, Clojure, or Scala to be used with Maven.
