SBuild is a Scala-based build system. It features platform independence, multi project support, automatic detection of needed actions, automatic up-to-date detection, a flexible scheme handler mechanism, Maven repository support, Ant task integration, automatic cross-project resolving of dependencies, high speed, a simple "syntax" that requires almost no Scala knowledge, behind-the-sceens compilation of build script to bytecode for fast execution time, and built-in scheme handlers for HTTP and Maven.
DEMUX Framework enables Java developers to build modular, cross-platform applications which can run on desktop, Web, and mobile and embedded devices. It is based on OSGI and supports creating JavaFX desktop applications, mobiles apps (Android, iOS, Windows), and Web applications.
Spinneret is a structured storage engine that can be thought of as an extended tuple storage system. It takes the best aspects of relational, object, and hierarchical databases and throws away the dead weight associated with those technologies. The benefit of Spinneret is that its data model is incredibly flexible, allowing it to expose its underlying data in any number of ways. It operates similar to an object database, but without hard ties to an originating language, and can also behave like a relational database without the burden of complex joins.
SWTBot is a Java-based functional testing tool for testing SWT and Eclipse based applications. It provides APIs that are simple to read and write and hide the complexities involved with SWT and Eclipse. This makes it suitable for functional testing by everyone. A set of assertions that are useful for SWT are provided, and you can also use your own assertion framework. A recorder and driver are provided for recording and playing back tests along with Ant tasks so that you can run your builds from within CruiseControl or other CI tools.
FitNesse Maven Classpath Plugin is a Maven2 plugin that collects the dependencies of the entire project, including its sub-modules. After resolving the artifacts, it generates the classpath and inserts it into the Fitnesse test suites, thus solving the problem of maintaining the correct classpath in FitNesse.
Butterfly Web UI is a component based Java Web application framework. Like the rest of the Butterfly Components, Butterfly Web UI is extremely small and very flexible. Butterfly Web UI uses Butterfly Container internally, a state of the art dependency injection container. Using Butterfly Web UI, it is easy both to generate HTML for a Web browser or XML or JSON for a RIA frontend (Flex, JavaFX, Silverlight) or AJAX frontend. You also can easily create HTML layout templates that are reused throughout your Web application, so you don't have the layout hardcoded into every page. You can easily mix RIA and non-RIA Web application technology in the same Web application.
