Bear is a lightweight remote automation tool for Groovy/Java/JVM. It allows you to deploy projects, setup your cluster, and install software to your remote machines. It differs from other existing tools in that it uses a programmatic approach - your deployment is a regular Java class. It also uses static types, chained method calls, FP, and fluent programming techniques.
Groowiki is a Wiki program and a document management system together. It is a wiki program that utilizes Subversion, Groovy, Velocity, and many more existing products. It lets you edit Wiki pages in a tree structure just like any other wiki, but it also gives you SVN access that makes it very easy to add files to the content. It stores everything in SVN. This way all information is versioned and (optionally) accessible offline, and you can upload your modifications in batches. This is especially useful if you work with large files and the Wiki pages mainly summarize the contents of the documents.
Xtempore is a lightweight, modular, and powerful XML-based domain independent templating language. It's essentially a programming library which provides flexible tools for transforming an object (model) and an XML document (template) into another XML document. Xtempore is implemented in Java and requires JRE 1.5 or later and slf4j for logging.
Kundo provides a structured, convention based approach for Java builds. Kundo has a pluggable, extensible architecture; it harnesses the power and flexibility of Groovy and Ant to provide a highly configurable Java build framework. Kundo achieves this flexibility with a plug-in architecture that attaches behaviors (provided by Kundo plug-ins) to build lifecycle phases. Kundo consists of a kernel and a set of foundation plug-ins. The kernel is responsible for the orchestration of the multiple collaborators within the build system.
