OpenOffice Gradle Integration
Gradle is a modern build framework for Java and Groovy applications and is released under the Apache 2.0 License. Gradle build scripts are written in Groovy rather than XML. Gradle manages the project dependencies which are fetched from local or remote Maven or Ivy repositories or Gradle can use local files as well.
There a few parallel efforts to this with the first being a Groovy UNO Extension that adds convenience methods to the Java UNO API's that allow much less code when using Groovy compared to Java.
The second effort is Lazybones templates to create Gradle build based UNO Extensions. Lazybones is a project creation tool that allows you to create a new project structure for any framework or library for which the tool has a template. The first and only template completed so far is for an OpenOffice Client.
