loader constraint violation: when resolving method

I'm implementing jira plugin, which uses Atlassian Marketplace java client.

When I try to access the Marketplace, I receive an error:

loader constraint violation: when resolving method "com.atlassian.fugue.Either.fold(Lcom/google/common/base/Function;Lcom/google/common/base/Function;)Ljava/lang/Object;" the class loader (instance of org/apache/felix/framework/BundleWiringImpl$BundleClassLoaderJava5) of the current class, com/atlassian/marketplace/client/model/Link, and the class loader (instance of org/apache/catalina/loader/WebappClassLoader) for the method's defining class, com/atlassian/fugue/Either, have different Class objects for the type com/google/common/base/Function used in the signature

 

Do you have any ideas how too deal with that? 

See below my maven dependencies
