What is the right Maven dependency for javax.jms.* classes?

In ActiveMQ as well as some other projects like Qpid JMS we pull in the JMS spec classes from Apache Geronimo JARs, the 1.1 APIs are available in this dependency:

  <dependency>
    <groupId>org.apache.geronimo.specs</groupId>
    <artifactId>geronimo-jms_1.1_spec</artifactId>
    <version>1.1.1</version>
  </dependency>

For JMS 2 APIs you’d need to use a different dependency, for instance

  <dependency>
    <groupId>org.apache.geronimo.specs</groupId>
    <artifactId>geronimo-jms_2.0_spec</artifactId>
    <version>1.0-alpha-2</version>
  </dependency>

These are both Apache 2.0 licensed dependencies.

Another option which is not Apache licensed is here as others have pointed out.

<dependency>
    <groupId>javax.jms</groupId>
    <artifactId>javax.jms-api</artifactId>
    <version>2.0.1</version>
</dependency>
