# Wrapper

API Documentation: | `Wrapper`

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.

### Properties

Property | Description
`archiveBase` | The archive base specifies whether the unpacked wrapper distribution should be stored in the project or in the gradle user home dir.
`archivePath` | The path where the gradle distributions archive should be saved (i.e. the parent dir). The path is relative to the archive base directory.
`distributionBase` | The distribution base specifies whether the unpacked wrapper distribution should be stored in the project or in the gradle user home dir.
`distributionPath` | The path where the gradle distributions needed by the wrapper are unzipped. The path is relative to the distribution base directory
`distributionUrl` | The URL to download the gradle distribution from.
`gradleVersion` | The gradle version for the wrapper.
`jarFile` | The file to write the wrapper jar file to.
`propertiesFile` | The file to write the wrapper properties to.
`scriptFile` | The file to write the wrapper script to.

### Property details

#### `PathBase` `archiveBase`

The archive base specifies whether the unpacked wrapper distribution should be stored in the project or in the gradle user home dir.

Default:
  `PathBase.GRADLE_USER_HOME`

#### `String` `archivePath`

The path where the gradle distributions archive should be saved (i.e. the parent dir). The path is relative to the archive base directory.

Default:
  `'wrapper/dists'`

#### `PathBase` `distributionBase`

The distribution base specifies whether the unpacked wrapper distribution should be stored in the project or in the gradle user home dir.

Default:
  `PathBase.GRADLE_USER_HOME`

#### `String` `distributionPath`

The path where the gradle distributions needed by the wrapper are unzipped. The path is relative to the distribution base directory

Default:
  `'wrapper/dists'`

#### `String` `distributionUrl`

The URL to download the gradle distribution from.

If not set, the download URL is the default for the specified `Wrapper.getGradleVersion()`.

If `Wrapper.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.

Default:
  `"http\://services.gradle.org/distributions/gradle-${gradleVersion}-bin.zip"` (or `"http\://services.gradle.org/distributions-snapshots/gradle-${gradleVersion}-bin.zip"` for snapshot versions).

#### `String` `gradleVersion`

The gradle version for the wrapper.

Default:
  `gradle.gradleVersion`

#### `File` `jarFile`

The file to write the wrapper jar file to.

Default:
  ``${project.projectDir}`/gradle/wrapper/gradle-wrapper.jar`

#### `File` `propertiesFile` (read-only)

The file to write the wrapper properties to.

Default:
  `jarFile`, replacing `.jar` with `.properties`

#### `File` `scriptFile`

The file to write the wrapper script to.

Default:
  ``${project.projectDir}`/gradlew`
