Maven Plugins are not meant to be invoked programmatically.

They rely on values that are injected by the underlying plexus container.

So either you will have to find out how to inject those values or you will have to rely on the default mechanism.

One thing you can use is the Maven Invoker. With that, you can programmatically launch maven lifecycles, but they will execute in a separate VM. So if you need to change the model dynamically beforehand, you will need to serialize the model out to a temporary pom.xml and use that with maven invoker. This is heavy stuff, but I have done it successfully some two years ago.
