# Wrapper

@DisableCachingByDefault(because = "Updating the wrapper is not worth caching")
abstract class Wrapper : DefaultTask(source)

Generates scripts (for *nix and windows) which allow you to build your project with Gradle, without having to install Gradle.

When a user executes a wrapper script the first time, the script downloads and installs the appropriate Gradle distribution and runs the build against this downloaded distribution. Any installed Gradle distribution is ignored when using the wrapper scripts.

The scripts generated by this task are intended to be committed to your version control system. This task also generates a small `gradle-wrapper.jar` bootstrap JAR file and properties file which should also be committed to your VCS. The scripts delegate to this JAR.
