The iabgpp-extras and iabgpp-extras-jackson libraries provides an interface and ability to parse the GVL and CMP
List respectively. The iabgpp-extras-jackson library uses Jackson 2.10.3 to parse the GVL and CMP List JSON.

Example of parsing the GVL,
import com.iab.gpp.extras.jackson.Loader;
import com.iab.gpp.extras.gvl.Gvl;
String gvlContent = "...";
Loader loader = new Loader();
Gvl gvl = loader.globalVendorList(gvlContent);
Example of parsing the CMP List,
import com.iab.gpp.extras.jackson.Loader;
import com.iab.gpp.extras.cmp.CmpList;
String cmpListContent = "...";
Loader loader = new Loader();
CmpList cmpList = loader.cmpList(cmpListContent);
