Proximity is a cross between an HTTP proxy and a pro-active mirror. One of its primary uses is as Web application to serve as a Maven proxy on a company's intranet. This project is the logical predecessor of Sonatype Nexus.

An important bug was fixed. If using non-snapshot
and snapshot repositories together, and they
contain the same paths (not with the default
config), RC1 and former releases actually hid
metadata files from Maven2. This bug has been
fixed in RC2, and Proximity merges these metadata
files properly. Also, many improvements have been
made in the configurability of Proximity itself.
Some of them, like ProximityLogic
"externalization", repository "grouping", and
Repository Snapshot policies, have been introduced
as a solution to the aggregation problem and as a
response to submitted issues.
