How to overcome "Conflicting setter definitions for property "? - json

Question

I use com.fasterxml.jackson and io.swagger libraries. In my REST endpoint I use org.javamoney.moneta.Money type for a GET query. When deploying the war i get following exception 1;
I have followed this reference and wrote following code[2]; and registered it at #ApplicationPath. But still getting same issue.
Any guide would be really helpful?
#ApplicationPath("/rest")
public class RestApplication extends Application {
#Override
public Set<Class<?>> getClasses() {
HashSet<Class<?>> set = new HashSet<Class<?>>();
set.add(com.test.JsonMoneyProvider.class);
[2]
import javax.money.CurrencyUnit;
import javax.money.Monetary;
import javax.money.MonetaryAmountFactory;
import javax.ws.rs.ext.Provider;
import javax.xml.bind.annotation.XmlTransient;
import com.fasterxml.jackson.annotation.JsonIgnore;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.jaxrs.json.JacksonJsonProvider;
#Provider
public class JsonMoneyProvider extends JacksonJsonProvider {
public JsonMoneyProvider() {
ObjectMapper mapper = new ObjectMapper();
mapper.addMixIn(MonetaryAmountFactory.class, MixIn.class);
setMapper(mapper);
}
public static interface MixIn {
#JsonIgnore
#XmlTransient
MonetaryAmountFactory setCurrency(CurrencyUnit currency);
#JsonIgnore
#XmlTransient
default MonetaryAmountFactory setCurrency(String currencyCode) {
return setCurrency(Monetary.getCurrency(currencyCode));
}
}
}

Simply use this annotation on the deserialization setter method to indicate Jackson wich one to use: #com.fasterxml.jackson.annotation.JsonSetter
