Open Source Build Systems in Groovy

Alex incorporates convention based builds with easy extensibility. Alex also supports a DSL, which gets rid of the xml clutter offered by most build systems.

Gant is a build tool for scripting Ant tasks using Groovy code instead of XML to specify the build logic. A Gant build specification is just a Groovy script and so can bring all the power of Groovy to bear directly, something not possible with Ant scripts.

Gradle is a build system which provides: * A very flexible general purpose build tool like Ant. * Switchable, build-by-convention frameworks a la Maven (for Java and Groovy projects). * Powerful support for multi-project builds. * Powerful dependency management (based on Apache Ivy). * Full support for your existing Maven or Ivy repository infrastructure. * Support for transitive dependency management without the need for remote repositories and pom.xml or ivy.xml files (optional). * Ant tasks as first class citizens. * Groovy build scripts.

It is a set of plugins that provide a highly enriched integration of the Groovy language into Maven 2.

Maven Tools for Grails is a set of maven artifacts used to ease the building/development of Grails Application using maven 2.
