| Hi 
everyone,   I do not see an answer to the message I am copying below 
from the mailing list.  I am having the same problem after a STS 
upgrade.   My project is working fine, but I have those errors in my 
pom.xml which I do not understand, and do not know how to get rid of 
them.   After the upgrade I also had to delete all my local 
repository and download all dependencies again, as the No class found exception 
was poping up for all dependencies!!   Thank to all for the help you can give me.   Martin.   -----------------------------------------------------------------------------------------------------------------------   Vernon wrote:    The following error

resolution will not be reattempted until the
 update interval of nexus has 
elapsed or updates are forced

 Thanks,
