How connect to Bitbucket server using bitbucket rest api

[Dummy Account]

I want to use the dependency provided 

 <dependency>
    <groupId>com.atlassian.bitbucket.server</groupId>
    <artifactId>bitbucket-rest</artifactId>
    <version>4.0.0-eap1</version>
</dependency>

Can someone point me in the right direction to use this and create a new repository or users from Java code using maven? 

Cheers!
