In order for Gradle to automatically download all your SDK components, the license agreements for each of the components need to be accepted using the SDK manager UI in Android Studio.
If you have accepted the license agreements on one workstation, but wish to build your projects on a different one, you can export your licenses by copying the accepted licenses folder from the Android Sdk Home folder (this should be located at <android sdk home path>/licenses) of your current workstation, to the Android Sdk Home directory of the machine where you now want to build your projects.
If you haven’t previously accepted the license agreements anywhere else, you will have to open the Android Studio SDK Manager on the new machine, install all necessary components and accept their respective license agreements from there.
