If the system property 'downloader' is set that use that specific downloader. This is used from gradle by appending `-Ddownloader=ABCD to the command.
ABCD is one of DownloaderType.
The other variable is the static property `DEFAULT_DOWNLOADER` in DownloaderFactory, which can be easily changed as needed inside the IDE according to development needs`.
Normal workflow would be to first use the recording downloader and afterwards only use mocks, if the requests are always staying the same.
