title: Exception in thread "main" java.lang.NoClassDefFoundError: org/joda/time/ReadableInstant
body: <p>I built an executable jar using an ant script, the only external jar I used was joda-time 2.0. The ant build script "seemed" to work as I did not recieve any compile errors, and if I were to remove the jode-time 2.0.jar from the lib directory the build would indeed fail as expected. At any rate, after building the jar I get this error when I try to run with:</p>
  
  <p>java -jar myapp.jar</p>
  
  <p>Exception in thread "main" java.lang.NoClassDefFoundError: org/joda/time/ReadableInstant</p>
  
  <p>Any thoughts on this? I'm just not sure where to look, everything works just fine within Eclipse. thanks for any ideas</p>
