If you have the keystore file already, it can be as simple as adding a few parameters to your build command:

./gradlew assembleRelease \
 -Pandroid.injected.signing.store.file=$KEYFILE \
 -Pandroid.injected.signing.store.password=$STORE_PASSWORD \
 -Pandroid.injected.signing.key.alias=$KEY_ALIAS \
 -Pandroid.injected.signing.key.password=$KEY_PASSWORD

No permanent changes to your Android project necessary.
