        <title>Introduction to Jersey dependencies</title>

        <para>
            Jersey is built, assembled and installed using <link xlink:href="http://maven.apache.org/">Apache Maven</link>.
            Non-snapshot Jersey releases are deployed to the
            <link xlink:href="https://search.maven.org/">Central Maven Repository</link>. Jersey is also being deployed to
            <link xlink:href="https://oss.sonatype.org/">Sonatype Maven repositories</link>, which contain also Jersey SNAPSHOT
            versions. In case you would want to test the latest development builds check out the
            <link xlink:href="https://oss.sonatype.org/content/repositories/snapshots/org/glassfish/jersey">
                Sonatype Snapshots Maven repository</link>.
        </para>

        <para>
            An application that uses Jersey and depends on Jersey modules is in turn required to also include a set
            of 3rd party modules that Jersey modules depend on. Jersey is designed as a pluggable component
            architecture and different applications can therefore require different sets of Jersey modules. This also means that
            a set of external Jersey dependencies required to be included in the application dependencies may vary in each
            application based on the Jersey modules that are being used by the application.
        </para>

        <para>
            Developers using Maven or a Maven-aware build system in their projects are likely to find it easier to include and
            manage dependencies of their applications compared to developers using ant or other build systems that are not
            compatible with Maven. This document will explain to both maven and non-maven developers how to depend on
            Jersey modules in their application. Ant developers are likely to find the
            <link xlink:href="http://maven.apache.org/ant-tasks/index.html">Ant Tasks for Maven</link> very useful.

            <para>If you are using Glassfish application server, you don't need to package
                anything with your application, everything is already included. You just need to declare
                (provided) dependency on JAX-RS API to be able to compile your application.
