Q:

Update of Springframework-core in Maven is giving me a timeout

This is what it looks like:
artifact org.springframework:spring-core: checking for updates from glassfish-repository
WARNING] repository metadata for: 'artifact org.springframework:spring-core' could not be    retrieved from repository: glassfish-repository due to an error: Error transferring file:    Connection timed out

The glassfish-repository seems to not be reachable.  I don't understand why Maven is trying to connect to a glassfish-rep.  I thought it tries to reach the central-repository, which is available (I checked).  Well, I think I don't really understand this remote-repository-management of maven.  Maybe someone can help me out here? 

A:

You must have the glassfish-repository registered somewhere in your configuration, either in your pom.xml or ~/.m2/settings.xml.
