Issues

Customers with custom builds need some resources to be overriden.

Solutions

Check if the customization directory also contains a resources directory inside of it.
If it does, grab all files from inside the resources directory and copy them into res of each flavor, keeping the file structure.

Example:

-custom/
 |-resources/
 | |-mipmap/
 |   |-file1.png
 | |-file2.png
  -

• file2.png will be copied to res/file2.png
• file1.png will be copied to res/mipmap/file1.png

This is applied to all flavors. It doesn't allow flavor-specific resources for custom builds. A new custom build is needed in order to do it.

Testing

Tested manually.

Coverage will be added Soon™.

Test Coverage (Optional)

• I have added automated test to this contribution

How to Test

Force a customized build by adding a custom.json file:

val buildtimeConfiguration = getBuildtimeConfiguration(rootDir = rootDir,
    Customization.CustomizationOption.FromFile(rootProject.file("custom/custom-reloaded.json"))
)

Add a resources directory beside the custom-reloaded.json file.
Its content will be copied to all flavours.
