This is the beginnings of a plugin to implement a CopyAndTransform task in Gradle. This basically extends the existing Copy task to allow user-defined transforms to be applied to the destination files after copying. This is needed to support certain in-place file transforms (eg. digital signing on Windows) without compromising incremental build capability.

This is difficult to accomplish because I want to support DSL sugar to make this convenient for build authors, but the Gradle Copy task internals were designed to be non-extensible. In order to get around these limitations, I have unabashedly cribbed (and in some cases copied wholesale) a whole lot of work from the excellent [Gradle Linux Packaging Plugin] (https://github.com/nebula-plugins/gradle-ospackage-plugin) by Netflix. All credit for the CopySpec-enhancing mechanism used here goes to the authors of that plugin.

This is a work in progress and is not yet expected to be usable.

1. Get CopySpec enhancement working with the handful of hard-coded transforms I need.

2. Generalize the after-copy mechanic and make specific transforms user-definable.

3. Publish it.

• Rewrite the Gradle Copy task with extensibility in mind.

• Pull out the actual copy, making it just another user-definable action. This will make the task useful for processing any tree of files, but will affect the from/into semantics and up-to-date tracking.

• Implement copy as a DSL method so that it can be used within user-defined tasks.

• Implement an "eachChangedFile", that is, extend or decorate eachFile to iterate only over changed files during an incremental build.
