The same problem has happened to me which I had set two different swagger2 version dependency in pom.xml。
Remove the old version and the problem have resolved .

That method is totally there. Not sure what is causing this. Perhaps you have a stale io.swagger lying around?

Had the same issue. Quick fix was in dependencies.gradle added this:

swagger            : [
      "io.swagger:swagger-core:1.5.21",
      "io.swagger:swagger-annotations:1.5.21"
]

This ensured that the proper version was downloaded .. without this the version in .gradle/cache was 1.5.14 and was causing the issue
