To create a full distribution (includes sources and docs):

    ./gradlew :distributions-full:allDistributionZip

The full distribution will be created at `subprojects/distributions-full/build/distributions/gradle-<version>-all.zip`. You can then use it as a Gradle Wrapper local distribution:

    ./gradlew wrapper --gradle-distribution-url=file:/path/to/gradle-<version>-all.zip
