The easiest way is to use Maven . The reason I say this is because the artifact is the main artifact resteasy-client, but this artifact has dependencies on other artifacts. If I create a new Maven project, add only this dependency
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-client</artifactId>
<version>3.0.9.Final</version>
</dependency>
The project will involve all these artifacts.
