Error Upgrade 1811 Class AbstractCheckoutFlowStrategy

[amigley_bastardo]

Hi, I'm migrating from Hybris 6.4 to 1811 but by doing ant initialize, I'm getting an exception with the class:

Caused by: java.lang.NoClassDefFoundError: de/hybris/platform/acceleratorservices/checkout/flow/impl/AbstractCheckoutFlowStrategy

I have reviewed the addon of ext-accelerator\acceleratorservices\......\platform\acceleratorservices\checkout, of version 6.4 vs 1811 ... and in 1811 there isn't flow package containing that class and others

How do I solve this issue? Any idea?

Thank's!
