swagger是一个RestAPI接口设计工具。
能够自动生成很多编程语言的server端和client端代码。

IntelliJ IDEA 中安装了swagger-codegen插件（intellij_swagger_codegen-0.0.3.SNAPSHOT.zip）
但在生成server端的java代码时，报错：

  1. io.swagger.codegen.languages.AbstractJavaCodegen.postProcessModelsEnum(Ljava/util/Map;)Ljava/util/Map;
  2. java.lang.NoSuchMethodError: io.swagger.codegen.languages.AbstractJavaCodegen.postProcessModelsEnum(Ljava/util/Map;)Ljava/util/Map;

原因是，此插件依赖io.swagger:swagger-codegen:2.2.1，
而下载下来的插件zip包里，lib下包含了两个版本的swagger-codegen（2.1.6和2.2.1），
所以造成了版本冲突。

解决方法是，删掉zip包里的swagger-codegen-2.1.6.jar，重新打成zip包，重新安装插件。
