MessageBodyReader not found for media type=text/plain

[s2tu]

I used the raml-java-client-generator to generate jars for MashapeWeatherAPIClient which are later put in my Java project. When i try to run my java project I get an error. Can someone help me solve this?

package com.newpackage;

import org.mule.example.api.MashapeWeatherAPIClient;
import org.mule.example.resource.weatherdata.model.WeatherdataGETHeader;
import org.mule.example.resource.weatherdata.model.WeatherdataGETQueryParam;

public class TheMain {
public static void main(String[] args){
WeatherdataGETHeader header = new WeatherdataGETHeader();
header.setXMashapeKey("g9zsZDIplfmshIOO3pNVkHjHn1Kep13OsF3jsn4bVomnkRBy5x");
WeatherdataGETQueryParam queryParams = new WeatherdataGETQueryParam( -121.955236, 37.354108);

	MashapeWeatherAPIClient.create().weatherdata.get(queryParams, header);
}

}

My error is

Hi can you please attach the raml

[rscadrde]

Problem is probably that a few lines above
Weatherdata.java:52
the generated source shows
target.request(MediaType.APPLICATION_JSON_TYPE);
is requested always (should generate to TEXT_PLAIN_TYPE)

[rscadrde]

changing

final JVar invocationBuilder = body.decl(JMod.FINAL, cm.ref(Invocation.Builder.class), "invocationBuilder", targetVal.invoke("request").arg(cm.directClass(MediaType.class.getName()).staticRef("APPLICATION_JSON_TYPE")));

to

        // for compatibility to 0.1.1 version: default is json
        String tempMediaTypeRef = "APPLICATION_JSON_TYPE";
        if (returnType.equals(cm.ref(String.class))) {
        	tempMediaTypeRef = "TEXT_PLAIN_TYPE";
        }
		final JVar invocationBuilder = body.decl(JMod.FINAL, cm.ref(Invocation.Builder.class), "invocationBuilder", targetVal.invoke("request").arg(cm.directClass(MediaType.class.getName()).staticRef(tempMediaTypeRef)));

helps for this case but fails in case of json body without entities (e.g. global-type-body )

Looks like method signatures for
org.mule.client.codegen.RamlJavaClientGenerator.buildReturnType(JCodeModel, ActionType, Response, String, String)
needs to be changed to return a container with JType and the corresponding mimeType and then that mimeType passed to "request" in org.mule.client.codegen.clientgenerator.Jersey2RestClientGeneratorImpl.callHttpMethod(JCodeModel, JDefinedClass, JType, JBodyType, JType, JType, Action, ApiModel)
