Lavric,
Sorry for the confusion, but Peco was not implying that you edit each mapping file by hand – section 5.6 in MyEclipse 5.5M1 does detail the use of the ReverseEngineeringStrategy.
The ReverseEngineeringStrategy is not an option for earlier versions of MyEclipse, which is why you don’t see it in the documentation you are currently referring to.
Hope this helps.
