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.
JCatapult is a development platform written in Java. Built for modularization, JCatapult allows developers to build modules such as a blog, content-management system, wiki, or any other reusable set of features and use them across multiple applications. Built on top of open source technologies, JCatapult is a robust and scalable platform. However, it is also agile and lightweight because it uses a convention over configuration approach.
Gnasher alleviates developers from having to execute maven builds with the "-o" option (offline) to avoid accessing external repositories' metadata files. The SHA1 hash files and the missing pom metadata files for dependencies are created if they are missing. The next time the build is run, external repositories are not accessed and the build runs faster.
