title: Pitest (PIT Mutation Testing) exception with local dynamodb
body: <p>I'm recieving the following pi-test exception when I have local dynamoDB lib files in my java project with a gradle build. Seems pi-test tries to open the lib file. Could not find a way to exclude lib files from pi-test either.</p>
  
  <p><code>
  :pitest
  Exception in thread "main" org.pitest.util.PitError: error in opening zip file (/Users/user1/.gradle/caches/modules-2/files-2.1/com.almworks.sqlite4java/libsqlite4java-linux-i386/1.0.392/b193c62571061e68bddeaf8ee7d3a8569b945ea6/libsqlite4java-linux-i386-1.0.392.so)
  </code>
  How can I solve this issue and have the mutation test on the gradle project?</p>
