    <title>The Distribution Plugin</title>
    <note>
        <para>
            The distribution plugin is currently <link linkend="feature_lifecycle">incubating</link>. Please be aware that the DSL and other configuration may change in later Gradle versions.
        </para>
    </note>

    <para>
        The distribution plugin facilitates building archives that serve as distributions of the project.
        Distribution archives typically contain then executable application and other supporting files, such as documentation.
	</para>

    <section>
        <title>Usage</title>
        <para>To use the distribution plugin, include in your build script:</para>
        <sample id="useDistributionPlugin" dir="userguide/distribution" title="Using the distribution plugin">
            <sourcefile file="build.gradle" snippet="use-plugin"/>
        </sample>
        <para>
            The plugin adds an extension named "<literal>distributions</literal>" of type <apilink class="org.gradle.api.distribution.DistributionContainer" /> to the project.
            It also creates a single distribution in the distributions container extension named "<literal>main</literal>".
            If your build only produces one distribution you only need to configure this distribution (or use the defaults).
        </para>
        <para>
            You can run "<userinput>gradle distZip</userinput>" to package the main distribution as a ZIP, or "<userinput>gradle distTar</userinput>" to create
            a GZip compressed TAR file.
            The files will be created at "<literal><replaceable>$buildDir</replaceable>/distributions/<replaceable>$project.name</replaceable>-<replaceable>$project.version</replaceable>.<replaceable>«ext»</replaceable></literal>".
        </para>
        <para>
            You can run "<userinput>gradle installDist</userinput>" to assembles the distribution content, uncompressed, into "<literal><replaceable>$buildDir</replaceable>/install/<replaceable>main</replaceable></literal>".
        </para>
    </section>

    <section>
        <title>Tasks</title>

            This will add following tasks to the project:

        <para>
            Given that the project name is "<literal>myproject</literal>" and version "<literal>1.2</literal>", running "<userinput>gradle customDistZip</userinput>" will produce a
            ZIP file named "<literal>myproject-custom-1.2.zip</literal>".
        </para>
        <para>
            Running "<userinput>gradle installCustomDist</userinput>" will install the distribution contents into "<literal><replaceable>$buildDir</replaceable>/install/custom</literal>".

    <section>
      <title>Distribution contents</title>
        <para>
            All of the files in the "<literal>src/<replaceable>$distribution.name</replaceable>/dist</literal>" directory will automatically be included in the distribution.
            You can add additional files by configuring the <apilink class="org.gradle.api.distribution.Distribution" /> object that is part of the container.
        </para>
        <sample id="configureDistribution" dir="userguide/distribution" title="Configuring the main distribution">
            <sourcefile file="build.gradle" snippet="configure-distribution"/>
        </sample>
        <para>
            In the example above, the content of the "<literal>src/readme</literal>" directory will be included in the distribution
            (along with the files in the "<literal>src/dist/main</literal>" directory which are added by default).
        </para>
        <para>
            The "<literal>baseName</literal>" property has also been changed. This will cause the distribution archives to be created with a different name.
