Springfox Swagger2 java.lang.NoSuchMethodError

Description: An issue about spring boot with swagger2 integration through spring-fox library. BeanCreationException: Error creating bean with name 'cachingOperationNameGenerator' defined in URL.

Tried to integrated swagger2 into current java project. Flowing [instructions], when the application start, NoSuchMethodError occurred. Did quite a lot of search on google, no related result.

The project is maven based with multiple language integrate including java, scala and kotlin.

Finally found the issue caused by the dependency of kotlin-compiler (1.3.x) in the maven plugin. The dependency embedded the guava library and the class com.google.common.collect.Maps was from kotlin-compiler.jar instead of guava dependency.

One the solution i used to overcome is down grade the kotlin-compiler dependency to 1.2.71 explicitly.

    <dependency>
      <groupId>org.jetbrains.kotlin</groupId>
      <artifactId>kotlin-compiler</artifactId>
      <version>1.2.71</version>
    </dependency>
