11. The integrated development environment of claim 10 wherein: the build script engine comprises a delta detection block, the delta detection block compares the processed App metadata, processed build rules and source code of the hybrid App with App metadata, build rules and source code of a previous version of the hybrid App, and generates a delta list comprising build steps based on the differences; and the build script generator generates the build scripts based on the build rules, App metadata, delta list and scheduling of build actions.
