8. The integrated development environment of claim 7 wherein the build script engine comprises: a build rules parser for processing the build rules from the build rules block; an App metadata parser for processing the App metadata; a build script generator, the build script generator generates the build scripts based on the processed build rules and processed App metadata; and a trigger generator for generating the build trigger after the build scripts are generated.
