Q:

how can I run the benchmark test?

This post has NOT been accepted by the mailing list yet.
I want to run the benchmark test, and the activemq version is 5.6.0. 
And I follow the steps 

but the maven says:  Unknown lifecycle phase "server". 
So what can I do?

A:

Ah yeah that doc is outdated.
With the ActiveMQ distribution there is an example you can use for performance testing.
In the root of the ActiveMQ distribution (eg such as 5.6.0)
cd examples
ant

And it display a usage page
Then you can use the ant producer to send in a lot of messages. And ant consumer to receive the messages.
