I have a java microprofile application that I want to add swagger to. The application has a "custom" Application class

@ApplicationPath("/api")
public class RestApplication extends Application {

    public RestApplication() {
        Swagger swagger = new Swagger();
        new SwaggerContextService().updateSwagger(swagger);

        BeanConfig beanConfig = new BeanConfig();
        beanConfig.setDescription("Parser for sheet music");
        beanConfig.setTitle("Ironfox");
        beanConfig.setVersion("0.0.0");
        beanConfig.setSchemes(new String[]{"http"});
        beanConfig.setBasePath("/api");
        beanConfig.setResourcePackage("se.pro12.ironfox");
        beanConfig.setScan(true);
    }
}

The problem is that it is failing on beanConfig.setScan(true) with the error 

java.lang.NoSuchMethodError: com.google.common.collect.Sets$SetView.iterator()Lcom/google/common/collect/UnmodifiableIterator;

And I don't really understand why. I've even tries adding a dependency to google-collections.

Has anyone seen this before or have any ideas of how to solve it?

the pom file that I have

您正在使用的 Payara Micro 版本 (4.1.2.173) 使用旧版本的 Guava 库 - v19，它不提供 Swagger 所需的方法。

你有几个选择：

  • 如文档中所述禁用类加载委托- 您可以在应用程序的 glassfish-web.xml 中本地执行此操作
  • 将较新版本的 guava 库复制到 Payara Micro JAR 中，覆盖现有的 guava.jarMICRO-INF/runtime
  • 等待几天，直到 Payara Micro 5.182 发布并使用 MicroProfile Open API 而不是 Swagger

升级到更新版本的 Payara Micro 并没有帮助，因为它仍然使用相同版本的 Guava 库。
