The instructions in this README explain how to create a CIPD package that contains the gradle build-time dependency of the Android embedding of the Engine. The Android embedder is shipped to Flutter end-users, but gradle is not.
These steps use gradle version 7.5.1 as an example.
unzip gradle-7.5.1-all.zip
cipd auth-login
cipd create -in gradle-7.5.1 -install-mode copy -tag version:7.5.1 -name flutter/gradle
engine/src/flutter/DEPS
gradle entry to contain the tag from the command above.gclient sync
to verify that dependency can be fetched.
