Unable to create converter for class

I did everything, I followed everything. Here is my class, I am getting error and crash when I run my app:

```
package com.taskout.taskout.http.model.filteroptions;

import com.bluelinelabs.logansquare.annotation.JsonField;
import com.bluelinelabs.logansquare.annotation.JsonObject;

@JsonObject(fieldDetectionPolicy = JsonObject.FieldDetectionPolicy.ANNOTATIONS_ONLY)
public class Session
{
@JsonField private String login;
@JsonField private String password;
@JsonField private String apikey;

public void setApiKey(String apiKey)
{
this.apikey = apiKey;
}

public void setLogin(String login)
{
this.login = login;
}

public void setPassword(String password)
{
this.password = password;
}

public String getLogin()
{
return login;
}

public String getPassword()
{
return password;
}

public String getAPIKey()
{
return apikey;
}

public Session(String username, String pw)
{
login = username;
password = pw;
}
}

```

I do not understand that is suppose to be simple and I almost pulled my hair out just to figure out whats wrong. Can't figure out what I missed either.

Start by reproducing the converter-generation failure for the shown Session class and inspect the generated output or build error. Check LoganSquare's model and converter-generation entry points to identify what prevents this class from being handled; done means the converter is generated successfully and the app no longer crashes.
