Swagger 3 and Java >= 9 Jigsaw

Question

I'm having trouble by configuring Swagger 3 on my maven-based Java11 application.

First I have declared in the pom.xml:

    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger2</artifactId>
        <version>3.0.0</version>
    </dependency>
    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger-ui</artifactId>
        <version>3.0.0</version>
    </dependency>

Then, I configure Swagger using Spring Beans:

@Configuration
@EnableSwagger2
public class SwaggerConfig {

@Bean
public Docket swaggerSpringMvcPlugin() {
    return new Docket(DocumentationType.SWAGGER_2)
            .select()
            .apis(RequestHandlerSelectors.basePackage("com.***.***.controller.rest"))
            .paths(PathSelectors.any())
            .build()
            .apiInfo(metaData());
}

private ApiInfo metaData() {
    return new ApiInfoBuilder().title("***")
            .description("***")
            .contact(new Contact("**", "www.***.com", "**"))
            .license("Apache 2.0")
            .licenseUrl("http://www.apache.org/licenses/LICENSE-2.0.html")
            .version("1.0.0")
            .build();
}

}

And finally, I have declared the module-info.java requires:

    requires springfox.swagger2;
    requires springfox.spring.web;
    requires springfox.core;

When I try to mvn clean install, I get the following error:

[INFO] -------------------------------------------------------------
[ERROR] COMPILATION ERROR :

I guess made a mistake but I can't find it. Could anyone help me?

At this moment, there is no official solution to solve this issue with. however by using maven-shade-plugin and merging the two springfox.core and springfox.spi jar in one package is the best workaround to run your project.

Add this dependency mentioned this URL: https://jitpack.io/#valery1707/springfox-assembly

requires springfox.assembly;

instead of

 requires springfox.core;
 requires springfox.spi
