It's trying to download from the remote repo and failing because the
network is unreachable, but doing
downloads the file no problem. I don't see the same problem on my
lappy and I don't have the same problem, neither do other devs on the
same network.
I don't have a proxy set up, and there are no proxy setting in my mvn
setting (global or user)
Any ideas?

interest does mvn -O clean work ok?

I would expect it to return 404 because that's not the repository
where that plugin lives, but I'm getting a Network Unreachable error,
the java httpclient, for some reason cannot access the network, but
the rest of the OS can ...

-o would work if I hadn't blatted my repository directory trying to
get this working :-)

seems plausible that the error is trying to say that maven can't
download the plugin it's looking for

blatted means deleted.
It's not that it can't find it, it can't access the network resource
at all, if I run it in less verbose mode I can see that it's running
through all the repos it knows about trying to downllad the same file,
central being the last one it tries (I should do something about that
order, I know)
[WARNING] Unable to get resource 'org.apache.maven.plugins:maven-clean-
plugin:pom:2.3' from repository central (http://repo1.maven.org/
maven2): Error transferring file: Network is unreachable
The fact that it says the network is unreachable is what confuses me,
why can't Maven's Wagon download the file when I can from the same
command line?
There are no proxy settings in my settings file, the one in /etc/
maven2 or the one in /usr/share/maven2/conf, is there another location
where java might look for proxy setting?
The same settings file works on other machines, both my laptop & other
developers. It has worked on this machine in the past too because I
had quite a full local repository before I deleted it.

1) removing settings.xml completely
2) having a basic settings.xml but explicitly define the
pluginRepository
?
just my two pennorth..
Stuart Grimshaw
have you tried...
1) removing settings.xml completely
2) having a basic settings.xml but explicitly define the
pluginRepository

It doesn't look like it's a Maven related problem at all, Eclipse
can't see any of it's update sites with the same error message:
Some sites could not be found. See the error log for more detail.

Is there a security manager policy setup to deny access to the network ?

"The update to netbase installs a new sysctl option to the system:
enygma@whitelight:~$ cat /etc/sysctl.d/bindv6only.conf
--- 8< --- 8< ---
This option makes it not possible to use the ::ffff::ip style mapped
addresses anymore, however, this is the default of the java virtual
machine, unless the specified define is used to suppress ipv6.
Setting the sysctl option to 0 makes java behave normal again."
