You can then use it as a Gradle Wrapper local distribution in a Gradle based project by using a `file:/` URL pointing to the built distribution:

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

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

    ./gradlew :distributions-full:allDistributionZip
