BuildInJava is a Java-driven build tool. This means that all "build scripts" are written in pure Java.
Benefits include:
Java goodness: Improved readability, flexibility, type-safety and performance. Seamless IDE integration: syntax highlighting and code completion for free.
Status: The project is in early stages of development. No builds are available yet and the API is still subject to change. Developers interested in contributing are encouraged to post on the mailing list.
