Re: java.lang.NoSuchFieldError: ROLE

Hi,

I deleted my repository and downloaded a new version without ibiblio 
configured and then ran maven keel:maven. I then had to re-enabled 
ibiblio to get all the other stuff and ran maven keel:maven again. Now 
my app works :-).

I don't know what hapenned here but perhaps the ibiblio repository is 
corrupt which doesn't give me a warm feeling at all. There are perhaps 
different jars lying around with the same version numbers! Is there 
another more trustworthy repository where I can get the jars that are 
not in the keel maven respository?

Thanks,
Max.
