7Bee is a Java-based build tool. 7Bee inherited some principles of Make.
Why another build tool when there is already make, gnumake, nmake, ant, jam, and others? Because all those tools have limitations that 7Bee an original author could not live with when developing software across multiple platforms using different products. Actually, an author had two objections before starting this project:
Usage of Make requires to install set of GNU tools
Ant did not meet to requirements of creation sophisticated build procedures, and had too big footprint
Why 7, because 7 is a number of base classes giving 7Bee implementation.
