如何使用Google Closure编译器构建一个文件？

Question

The question is a little more complicated than the title suggests, so allow me to elaborate. I have a project that is split into two repositories. The both use Google Closure for dependency management and compilation. I need to deliver a compiled version of project A to project B. Project B does advanced optimizations, so project A must be whitespace only. The problem is that I can't find a way to satisfy all my requirements for compiled A, which are:

• It must be ordered by dependency
• There can be no goog base code, ie, var goog=goog||{}...
• Similarly, there can be no goog.provides or goog.requires
• It must be whitespace-only compiled

So far I've tried:

• Closurebuilder.py
  • pros: can be whitespace only
  • problem: Has base code; getting duplicate namespace issues
• Compiler.jar
  • problem: whitespace-only mode keeps goog.provides and requires in
  • problem: any optimizations of project A break project B

Has anyone made a similar setup work?

Answer 1

I solved it by getting the dependencies from closurebuilder.py and simply concatenating them together, in order, into one file. It gets shipped to a built repo, where B can pick it up via npm, and it gets run through a closure script (that adv. optimizes it and splits it into modules).
