To actually compile and start the project, you need to have the references artifacts on your artifact repository. Access to Atlassian's artifacts should already been configured when you have installed the Atlassian SDK.

You need to download the projectdoc artifacts and install them manually since they are currently not available on a public repository.

Here are the coordinates of the compile time dependency (download trial version of the projectdoc Toolbox from the Atlassian Marketplace).

    <dependency>
      <groupId>de.smartics.atlassian.confluence</groupId>
      <artifactId>smartics-projectdoc-confluence</artifactId>
      <version>${version.smartics-projectdoc-confluence}</version>
    </dependency>

And this is the additional runtime dependency (download free version of the projectdoc Core Blueprints Add-on from the Atlassian Marketplace).
