com.realexpayments.hpp.sdk:rxp-hpp-android:2.3 does not recognize HPP classes

[jrbistuer]

When implementing the new version 2.3 from mavencentral, the HPP classes are not recognized:

import com.realexpayments.hpp.HPPError;
import com.realexpayments.hpp.HPPManager;
import com.realexpayments.hpp.HPPManagerListener;

the classes jar in the aar package downloaded seems to be empty.
