Interactive Communication - Print channel maven dependencies

Trying to write servlet to open a ICC print channel PDF using a servlet. Unable to find the dependencies for following

import com.adobe.fd.ccm.channels.print.api.exception.PrintChannelException;
import com.adobe.fd.ccm.channels.print.api.model.PrintChannel;
import com.adobe.fd.ccm.channels.print.api.model.PrintChannelRenderOptions;
import com.adobe.fd.ccm.channels.print.api.model.PrintDocument;
import com.adobe.fd.ccm.channels.print.api.service.PrintChannelService;

 Can you someone please let me know what it is the maven dependency to use for this. I have tried with  uber 6.5.11 , but but during build it says the following,

Could not resolve dependencies for project com.fmcc.cms:fmcc-cms.core:bundle:0.0.1-SNAPSHOT: Could not find artifact com.adobe.aem:uber-jar:jar:apis:6.5.11 in adobe-public-releases (https://repo.adobe.com/nexus/content/groups/public) =
Kindly let me know which dependencies to use to get the PrintChannel for Interactive Communication.

Thanks
