Compile fail with following error message in v6.7.0:
Incompatible type: oasis.names.specification.ubl.schema.xsd.commonaggregatecomponents_23.CommunicationType can not transfer to oasis.names.specification.ubl.schema.xsd.commonbasiccomponents_23.ValueType
Error in code as following:
DocumentDistributionType.java
@nonnull
public ValueType setCommunication(
@nullable
final String valueParam) {
ValueType aObj = getCommunication();
if (aObj == null) {
aObj = new ValueType(valueParam);
setCommunication(aObj);
} else {
aObj.setValue(valueParam);
}
return aObj;
}

Yes, this is an unfortunate error that occurs when compiling under Mac OS and has been fixed in a later version.
Please find the binary versions in Maven Central under https://repo1.maven.org/maven2/com/helger/ubl/
