Maven: no existe io.swagger.annotations paquete

sotne:

Quiero documentar mi proyecto con arrogancia. Puedo añadir anotaciones de la fanfarronería y dependencias io.springfox a mi proyecto, pero cuando corro mvn clean packagetengo una gran cantidad de errores:

PS D:\parent-project> mvn clean package

Una de las clases con las anotaciones de la fanfarronería (las otras clases tienen las mismas anotaciones pero el código diferent):

import java.io.Serializable;
import java.util.Optional;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;

@ApiModel
public class ResponseSimple implements Serializable {
  transient private static final long serialVersionUID = 5106222175899418836L; 
  private ResponseInfo responseInfo = new ResponseInfo(); 

  @ApiModelProperty(notes = "Response info")
  public ResponseInfo getResponseInfo() { 
    return responseInfo; 
  } 

  public void setResponseInfo(ResponseInfo responseInfo) { 
    this.responseInfo = responseInfo; 
  }

  @Override 
  public String toString() { 
    return Optional.of(responseInfo).map(ri -> ri.toString()).orElse(""); 
  }
}

He Maven 3.5.4

¿Alguien sabe por qué no funciona?

David Conneely:

En su module-common-lib/pom.xmlarchivo, sólo se refiere a la io.springfix:springfox-swagger2dependencia en el <dependencyManagement>elemento.

En el POM niño, el <dependencies>elemento no necesita estar dentro de un <dependencyManagement>elemento, ya que están consumiendo la dependencia (no sólo la gestión de su versión, el alcance, las exclusiones y así sucesivamente para el consumo posterior - que es lo que hace el POM padre).

Básicamente, el hecho de que la dependencia io.springfox:springfox-swagger2es sólo en los <dependencyManagement>medios de sección que él (y, más importante aún, también su dependencia transitiva io.swagger:swagger-annotationsque contiene el io.swagger.annotationspaquete) no se añade a la ruta de clase compilación.

Esto se puede comprobar mediante la ejecución mvn dependency:build-classpathpara ver la ruta de clases que construye Maven.

La solución es eliminar las líneas <dependencyManagement>y </dependencyManagement>en module-common-lib/pom.xml(pero no desde parent-project/pom.xml, donde el elemento sirve a su propósito pretendido).
