== Configuring {xpack} Java Clients

deprecated[7.0.0, The `TransportClient` is deprecated in favour of the {java-rest}/java-rest-high.html[Java High Level REST Client] and will be removed in Elasticsearch 8.0. The {java-rest}/java-rest-high-level-migration.html[migration guide] describes all the steps needed to migrate.]

If you want to use a Java {javaclient}/transport-client.html[transport client] with a
cluster where {xpack} is installed, then you must download and configure the
{xpack} transport client.

. Add the {xpack} transport JAR file to your *CLASSPATH*. You can download the {xpack}
distribution and extract the JAR file manually or you can get it from the
https://artifacts.elastic.co/maven/org/elasticsearch/client/x-pack-transport/{version}/x-pack-transport-{version}.jar[Elasticsearch Maven repository].
As with any dependency, you will also need its transitive dependencies. Refer to the
https://artifacts.elastic.co/maven/org/elasticsearch/client/x-pack-transport/{version}/x-pack-transport-{version}.pom[X-Pack POM file
for your version] when downloading for offline usage.

. If you are using Maven, you need to add the {xpack} JAR file as a dependency in
your project's `pom.xml` file:
+
--
[source,xml]
--------------------------------------------------------------
<project ...>
     <repositories>
     <!-- add the elasticsearch repo -->
      <repository>
         <id>elasticsearch-releases</id>
         <url>https://artifacts.elastic.co/maven</url>
         <releases>
          <enabled>true</enabled>
         </releases>
         <snapshots>
            <enabled>false</enabled>
         </snapshots>
      </repository>
      ...
   </repositories>
   ...

   <dependencies>
      <!-- add the x-pack jar as a dependency -->
      <dependency>
         <groupId>org.elasticsearch.client</groupId>
         <artifactId>x-pack-transport</artifactId>
              <version>{version}</version>
      </dependency>
      ...
   </dependencies>
   ...

</project>
--------------------------------------------------------------
--

. If you are using Gradle, you need to add the {xpack} JAR file as a dependency in
your `build.gradle` file:
+
--
[source,groovy]
--------------------------------------------------------------
repositories {
  /* ... Any other repositories ... */

  // Add the Elasticsearch Maven Repository
  maven {
    name "elastic"
    url "https://artifacts.elastic.co/maven"
  }
}

dependencies {
  compile "org.elasticsearch.client:x-pack-transport:{version}"

  /* ... */
}
--------------------------------------------------------------
--

. If you are using a repository manager such as https://www.sonatype.com/nexus-repository-oss[Nexus OSS] within your
company, you need to add the repository as per the following screenshot:
+

image::security/images/nexus.png["Adding the Elastic repo in Nexus",link="images/nexus.png"]

Then in your project's `pom.xml` if using maven, add the following repositories and dependencies definitions:

[source,xml]
--------------------------------------------------------------
<dependencies>
    <dependency>
        <groupId>org.elasticsearch.client</groupId>
        <artifactId>x-pack-transport</artifactId>
        <version>{version}</version>
    </dependency>
</dependencies>

<repositories>
    <repository>
        <id>local-nexus</id>
        <name>Elastic Local Nexus</name>
        <url>http://0.0.0.0:8081/repository/elasticsearch/</url>
        <releases>
            <enabled>true</enabled>
        </releases>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </repository>
  </repositories>
--------------------------------------------------------------

. If you are using {stack} {security-features}, there are more configuration
steps. See {ref}/java-clients.html[Java Client and security].
