Move CmakeList.txt generation after clean task

Thank you for the nice plugin! 👍

While trying to replace my own implementation with this, I ran in to a somewhat a problem, so maybe some one else is also experiencing this.

I like to sometimes run a clean task before building my project (mostly when deploying), and with that task in place the compiler game me an error that the file specified in the externalNativeJsonGenerator.makefile property does not exist. Some investigation revealed that the CMakeLists.txt is generated in the afterEvaluate callback witch is executed before the clean task, so on the clean task the file is deleted. So I was wondering if it is plausible of moving the generation after the clean task? Maybe it can be hooked to after/before preBuild task?

The issue can be simulated with the sample projects by running a clean when building ./gradlew sample:clean sample:assemble

A problem was found with the configuration of task ':sample:generateJsonModelDebug'.
> File '/Users/darius/workspace/android/Cipher.so/sample/build/cipher.so/cmake/CMakeLists.txt' specified for property 'externalNativeJsonGenerator.makefile' does not exist.

@kibotu it looks like it’s caused by the file path, please try it again within the dev-SNAPSHOT channel

if still no work, show me more infos

I just encountered the same issue:

.../n4ma-hello/platforms/android/app/src/com/janeasystems/cdvnodejsmobile/jni/CMakeLists.txt' specified 
for property 'externalNativeJsonGenerator.makefile' does not exist.

Any progress on a fix?
