Android extend default locale

Issue

I have inherited an old android app, and the first thing I did, was change the build from Ant to gradle. The app builds fine, but when I try to run the release target, gradle fails complaining about missing translations.

The folder structure of the resource folder is: (the default language, in the values folder is en-GB)

res/
   values/
        /file1.xml
        /file2.xml
        /file3.xml
   /values-us/
        /file2.xml (containing just the few lines that differ from /value/file2.xml
   /values-dk/
         file1.xml
         file2.xml
         file3.xml

So, basically the linter is correct, most of the files are missing in the values-us folder. However, a single locale contains about 20 files, with around 100+ lines each, and the difference between the default and US is probably 5 lines total, it seems impractical to have to maintain all values for both locales. To be clear, I absolutely want the release target to fail, when values-dk/ or values-de/ are missing translations, I's just like some way to mark the US locale as an extension of the default. Is this possible?

Solution

So it turns out this is actually pretty simple. All I had to do was rename the values-us/ folder to values-en-rUS/ and it works.
