That error usually means that you have more than 1 jar file in your project with a class ConnectedComponents in the package edu.stanford.npl.graph.

Make sure you are adding the JAR file only once, and check also if you have 2 different JARs which may have the very same class.

By removing the duplicities, your application should work.

This type of error are occur mostly in two reason :

first as @zozelfelfo said : including multiple jar file, as you include same jar in lib and your main project so it doing duplicate,

   -> removing the duplicities jar files

Seconds you are forgot to include one of the necessary jar file in your lib,due to it, show error multiple dex file- class not founds.

  -> check for necessary jar file if any forgot
