Я хочу документировать свой проект с помощью Swagger.Я добавляю аннотации swagger и зависимости io.springfox в свой проект, но когда я запускаю mvn clean package, у меня много ошибок: 

PS D:\parent-project> mvn clean package

Один из классов с аннотациями swagger (другие классы имеют те же аннотации, но другой код): 

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(""); 
  }
}

У меня Maven 3.5.4

Кто-нибудь знает, почему он не работает?

В вашем файле module-common-lib/pom.xml вы ссылаетесь только на зависимость io.springfix:springfox-swagger2 в элементе <dependencyManagement>.

В дочернем POM элемент <dependencies> не обязательно должен находиться внутри *Элемент 1007 *, поскольку вы потребляете зависимость (а не просто управляете ее версией, областью действия, исключениями и т. Д. Для последующего использования - это то, что делает родительский POM).

В основном тот факт, что зависимость io.springfox:springfox-swagger2 только в разделе <dependencyManagement> означает, что он (и, что более важно, его транзитивная зависимость io.swagger:swagger-annotations, содержащая пакет io.swagger.annotations) не добавлен в путь к классам компиляции.

Вы можете проверитьэто путем запуска mvn dependency:build-classpath, чтобы увидеть путь к классу, который строит Maven.

Исправление заключается в удалении строк <dependencyManagement> и </dependencyManagement> в module-common-lib/pom.xml (но NOT из parent-project/pom.xml, где элемент служит по прямому назначению).
