Jackson JSON deserialization with multiple parameters constructor
<p>I've been using FasterXML/Jackson-Databind in my project for a while now, and all was working great, until I've discovered this <a href="https://manosnikolaidis.wordpress.com/" rel="noreferrer">post</a> and started to use this approach to desserialize objects without the @JsonProperty annotations.</p>

<p>The problem is that when I have a constructor which take multiple parameters and decorate this constructor with the @JsonCreator annotation Jackson throw the following error: </p>

<pre><code>Exception in thread "main" com.fasterxml.jackson.databind.JsonMappingException: 
Argument #0 of constructor [constructor for com.eliti.model.Cruiser, annotations: {interface com.fasterxml.jackson.annotation.JsonCreator=@com.fasterxml.jackson.annotation.JsonCreator(mode=DEFAULT)}] has no property name annotation; must have name when multiple-parameter constructor annotated as Creator
 at [Source: {
  "class" : "com.eliti.model.Cruiser",
  "inventor" : "afoaisf",
  "type" : "MeansTransport",
  "capacity" : 123,
  "maxSpeed" : 100
}; line: 1, column: 1]
</code></pre>

<p>I've created a <a href="https://github.com/pedro-stanaka/test-error-jackson" rel="noreferrer">little project</a> to illustrate the problem, the class I'm trying to desserialize is this one:</p>

<pre class="lang-java prettyprint-override"><code>public class Cruise extends WaterVehicle {

 private Integer maxSpeed;

  @JsonCreator
  public Cruise(String name, Integer maxSpeed) {
    super(name);
    System.out.println("Cruise.Cruise");
    this.maxSpeed = maxSpeed;
  }

  public Integer getMaxSpeed() {
    return maxSpeed;
  }

  public void setMaxSpeed(Integer maxSpeed) {
    this.maxSpeed = maxSpeed;
  }

}
</code></pre>

<p>And the code to desserialize is like this: </p>

<pre><code>public class Test {
  public static void main(String[] args) throws IOException {
    Cruise cruise = new Cruise("asd", 100);
    cruise.setMaxSpeed(100);
    cruise.setCapacity(123);
    cruise.setInventor("afoaisf");

    ObjectMapper mapper = new ObjectMapper().enable(SerializationFeature.INDENT_OUTPUT);
    mapper.registerModule(new ParameterNamesModule(JsonCreator.Mode.PROPERTIES));

    String cruiseJson = mapper.writeValueAsString(cruise);

    System.out.println(cruiseJson);

    System.out.println(mapper.readValue(cruiseJson, Cruise.class));

}
</code></pre>

<p>I already tried to remove the @JsonCreator, but if I do so, the throws the following exception:</p>

<pre><code>Exception in thread "main" com.fasterxml.jackson.databind.JsonMappingException: Can not construct instance of com.eliti.model.Cruise: no suitable constructor found, can not deserialize from Object value (missing default constructor or creator, or perhaps need to add/enable type information?)
 at [Source: {
  "class" : "com.eliti.model.Cruise",
  "inventor" : "afoaisf",
  "type" : "MeansTransport",
  "capacity" : 123,
  "maxSpeed" : 100
}; line: 3, column: 3]
</code></pre>

<p>I have tried to issue a "mvn clean install", but the problem persists.</p>

<p>Just to include some extra information, I've researched thoroughly about this problem (GitHub issues, Blog posts, StackOverflow Q&amp;A). Here are some debbuging/investigation that I have been doing on my end:</p>

<h3>Investigation 1</h3>

<p><strong>javap -v</strong>  on the generated bytecode give me this:</p>

<pre><code> MethodParameters:
      Name                           Flags
      name
      maxSpeed
</code></pre>

<p>When talking about the constructor, so I guess that the <strong>-parameters</strong> flag is really being set for javac compiler.</p>

<h3>Investigation 2</h3>

<p>If I create a constructor with a single parameter the object gets initialized, but I want/need to use the multiple parameter constructor.</p>

<h3>Investigation 3</h3>

<p>If I use the annotation @JsonProperty on each field it works as well, but for my original project it is too much overhead since I have a lot of fields in the constructor (and also it gets very hard to refactor code with annotations).</p>

<p>The question that remain is:
<strong>How can I make Jackson work with multiple parameter constructor without annotations?</strong></p>
