Invicta is an open-source build management tool. Using simple project definition files, it generates powerful build scripts (Apache ANT’s), while hiding their complexity. Furthermore, Invicta is a modular framework that allows advanced developers add their own customized types of components, which means writing once ANT code that can later be used by all the developers in their project or company simply by specifying the new type name.
