Conflicting setter definitions for property \“currency\”: javax.money.MonetaryAmountFactory

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 ;

Caused by: java.lang.IllegalArgumentException: Conflicting setter definitions for property "currency": javax.money.MonetaryAmountFactory#setCurrency(1 params) vs javax.money.MonetaryAmountFactory#setCurrency(1 params) at com.fasterxml.jackson.databind.introspect.POJOPropertyBuilder.getSetter(POJOPropertyBuilder.java:293) at io.swagger.jackson.ModelResolver.resolve(ModelResolver.java:246) at io.swagger.jackson.ModelResolver.resolve(ModelResolver.java:127) at io.swagger.converter.ModelConverterContextImpl.resolve(ModelConverterContextImpl.java:99) at io.swagger.jackson.ModelResolver.resolveProperty(ModelResolver.java:106) a

I have followed this reference (http://stairs-jumper.livejournal.com/33244.html) and wrote following code snippet[2]; and registered it at @ApplicationPath. But still getting same issue.

    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));
            }
        }
    }

Registering;

@ApplicationPath("/rest")
public class RestApplication extends Application {
@Override
    public Set<Class<?>> getClasses() {
        HashSet<Class<?>> set = new HashSet<Class<?>>();
        set.add(com.test.JsonMoneyProvider.class);

Maybe will be useful even with this huge delay: If you’re using swagger-maven-plugin validate version. I’ve fount that in version 3.1.4 is very old version of FaxterXML(1.9.X branch) Fix for it already placed in the 3.1.5-SNAPSOT of this plugin

First: have you tried latest Jackson version (2.7.4)?
