Using the shaded JAR

The default driver JAR depends on Netty, which is used internally for networking.

This explicit dependency can be a problem if your application already uses another Netty version. To avoid conflicts, we provide a “shaded” version of the JAR, which bundles the Netty classes under a different package name:

<dependency>
  <groupId>${project.groupId}</groupId>
  <artifactId>cassandra-driver-core</artifactId>
  <version>2.0.12.3</version>
  <classifier>shaded</classifier>
  <!-- Because the shaded JAR uses the original POM, you still need
       to exclude this dependency explicitly: -->
  <exclusions>
    <exclusion>
      <groupId>io.netty</groupId>
      <artifactId>*</artifactId>
    </exclusion>
  </exclusions>
</dependency>
