[AndrewBystrov]

After clone the project, can't build the source, because gradle.build trying to execute app win plugin, but on linux it's make not sense

  ~/projects/others/jackfish
 $ ./gradlew build

> Configure project :
4.5.14.local_build

> Configure project :mocks:win
task 'buildMockWin' doesn't run because your actual OS is 'linux' but expected 'Windows'

> Task :plugins:app:win:nugetRestore FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':plugins:app:win:nugetRestore'.
> A problem occurred starting process 'command 'mono''
