# Upgrading the gradle wrappers Set `GRADLE_VERSION` to the version of gradle. Set `GRADLE_VERSION_CHECKSUM` to the "Binary-only (-bin) ZIP Checksum" for that version from https://gradle.org/release-checksums/. Then run: ``` for dir in . \ benchmark-overhead \ examples/distro \ examples/extension \ smoke-tests/fake-backend \ smoke-tests/grpc \ smoke-tests/matrix \ smoke-tests/play \ smoke-tests/springboot do (cd $dir && ./gradlew wrapper --gradle-version $GRADLE_VERSION \ --gradle-distribution-sha256-sum=$GRADLE_VERSION_CHECKSUM) done ```
