download with http 403 status code assumed by maven to be OK, then checksum
failed error

Affects Versions: 2.0.6
Environment: Win xp pro., JDK6, mvn 2.0.6, netbeans 6, mevenide
plugin in netbeans.
Reporter: Bruce Chapman
Priority: Minor
Our firewall/cache is blocking access to

thinks it has a virus (that's the not the problem)

but the firewall also returns content for the browser

The problem is that maven is ignoring the status code, goes ahead and downloads
the file then decides that the checksum for the content does not match what is
expected. This is misleading and makes it more difficult to diagnose the cause
of the failed download.
Here is what maven does
{{

Maven should only go on and download the file and compare checksums if the http
status is valid eg 200, in the case of a failing http status code, it would be
much more useful if maven failed earlier with the status code and text as the
error message.
