Personally   None of the answers above worked for me  I still kept getting NoClassDefFound errors  I am using Maven for dependencies    My solution was to build using  mvn clean install  and use the   project -jar-with-dependencies jar  that that command creates   Similarly in Eclipse you can right click the project -  Run As -  Maven Install and it will place the jars in the target folder
