Could be an Eclipse issue. Did you run it with Maven? Do you still get that error this way?

Im using Apache Ant.

Yes, still seeing it.

Thanks so much for your time.

My first reaction would be “no! why? please consider upgrading to at least the latest 1.4.x version and Maven…”. But eh.

Looking at the build script for 1.0.1, which is 11 commits away from the very first commit in the SDK’s history, it looks like you have the correct dependencies… So I’m thinking either build script problem or eclipse loader/runner problem.

updated to new version:
Now im seeing error: java.lang.ClassNotFoundException: net.spy.memcached.internal.AbstractListenableFuture

Do you know which lib that contains net.spy.memcached.internal.AbstractListenableFuture? I dont see it under spymemcached.jar

Thanks so much for your time.

I found the right version of spymemcached that contains AbstractListenableFuture.

Thanks.
