-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Ron,
I'm not sure if it's a better or worse solution. It does minimize the configuration effort. This is always a good thing when moving people from Ant to Maven. What it does illustrate (at least to me) is that the code base I'm working with has more technical debts that need to be addressed. Also, that the documentation is quite dense - you speed through it at your peril. . . . just my two cents /mde/ On 12/5/2014 7:36 PM, Ron Wheeler wrote: > Great.
