org.gradle.api.tasks.wrapper

## Class Wrapper

- java.lang.Object
- - org.gradle.api.internal.AbstractTask
  - - org.gradle.api.DefaultTask
    - - org.gradle.api.tasks.wrapper.Wrapper

- All Implemented Interfaces:
    Comparable<Task>, org.gradle.api.internal.DynamicObjectAware, org.gradle.api.internal.TaskInternal, ExtensionAware, Task, org.gradle.util.Configurable<Task>

      public class Wrapper
      extends DefaultTask

  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 delegates to this JAR.

      See Also:
        `setDistributionPath(String)`

    - #### setDistributionPath

          public void setDistributionPath(String distributionPath)

      Returns the type of the Gradle distribution to be used by the wrapper.

      The type of the Gradle distribution to be used by the wrapper. By default, this is `Wrapper.DistributionType.BIN`, which is the binary-only Gradle distribution without documentation.

      If `getGradleVersion()` is not set, will return null.

      The wrapper downloads a certain distribution only once and caches it. If your distribution base is the project, you might submit the distribution to your version control system. That way no download is necessary at all. This might be in particular interesting, if you provide a custom gradle snapshot to the wrapper, because you don't need to provide a download server then.
