Install Java client library

The latest version of the Pulsar Java client library is available via Maven Central. To use the latest version, add the pulsar-client library to your build configuration.

:::tip

• pulsar-client and pulsar-client-admin shade dependencies via maven-shade-plugin to avoid conflicts of the underlying dependency packages (such as Netty). If you do not want to manage dependency conflicts manually, you can use them.
• pulsar-client-original and pulsar-client-admin-original does not shade dependencies. If you want to manage dependencies manually, you can use them.

:::

Maven

If you use Maven, add the following information to the pom.xml file.

<!-- in your <properties> block -->
<pulsar.version>@pulsar:version@</pulsar.version>

<!-- in your <dependencies> block -->
<dependency>
  <groupId>org.apache.pulsar</groupId>
  <artifactId>pulsar-client</artifactId>
  <version>${pulsar.version}</version>
</dependency>

Gradle

If you use Gradle, add the following information to the build.gradle file.

def pulsarVersion = '@pulsar:version@'

dependencies {
    compile group: 'org.apache.pulsar', name: 'pulsar-client', version: pulsarVersion
}

Connect to Pulsar cluster

To connect to Pulsar using client libraries, you need to specify a Pulsar protocol URL.

You can assign Pulsar protocol URLs to specific clusters and use the pulsar scheme. The following is an example of localhost with the default port 6650:

pulsar://localhost:6650

If you have multiple brokers, separate IP:port by commas:

pulsar://localhost:6550,localhost:6651,localhost:6652

If you use mTLS authentication, add +ssl in the scheme:

pulsar+ssl://pulsar.us-west.example.com:6651
