maven-shade-plugin has detected that some class files are
present in two or more JARs. When this happens, only one
single version of the class is copied to the uber jar.
Usually this is not harmful and you can skip these warnings,
otherwise try to manually exclude artifacts based on
mvn dependency:tree -Ddetail=true and the above output.
See http://maven.apache.org/plugins/maven-shade-plugin/
