This is in reference to this:

https://github.com/jmeter-maven-plugin/jmeter-maven-plugin/issues/121

The following dependencies are not available in maven central.

event:event:jar:1.0
d-haven-managed-pool:d-haven-managed-pool:jar:1.0

The only similar artefacts I can find are:

<dependency>
	<groupId>d-haven-event</groupId>
	<artifactId>d-haven-event</artifactId>
	<version>1.0.3</version>
</dependency>

and 

<dependency>
	<groupId>d-haven-mpool</groupId>
	<artifactId>managed-pool</artifactId>
	<version>1.0</version>
</dependency>

This means that you can't build JMeter from maven central at the moment because of transitive dependency issues.
