TaskScheduler not found

I was trying to upgrated to Spring integration 2.0.M1. However while extending my Aggregator from DefaultMessageAggregator. I get this compilation exception.

If there any dependency which I am missing? My Spring Core is version 2.5.5


[INFO] Compilation failure

I think you're missing Spring 3.0.0.x.

Also I recommend using BufferingMessageHandler as and extension point, instead of DefaultMessageAggregator. It is intended to be easier to extend, so I'd like to have it tried out as much as possible.
