Maven wants to get plugin versions that don't exist
I'm not sure what I did to screw things up, but lately it is failing
to download plugins because it is trying to use a version that doesn't
exist. I'm using Nexus as a mirror of everything.
E.g., I just tried to do a "mvn archetype:create" to create a new
plugin and it gave an error because it's trying to download the
maven-archetype-plugin version 2.0-alpha-6, which doesn't exist.
What did I do that screwed things up? Is something wrong with Nexus?
Do I need to do a sync or something?
Thanks,
Phillip
P.S. Here's the actual output:
C:\mycomps\maven\plugin\hello>mvn archetype:create

Thanks; unfortunately, it didn't help.

Yep, that's what I've been having to do.

Usually when Maven is trying to update plugin snapshots, it's because
one has gotten into your local repository.
Try removing the directory tree for the archetype plugin from your
local repo, and see if it goes back to using the released version.
You can also use the long form of the plugin execution command, and
specify groupId:artifactId:version to force it to use the version you
want.

There's a Nexus Users list that would be more appropriate for this
line of questioning...

I tried Expire Cache, Rebuild Metadata, ReIndex, etc. and I'm still
having problems :( How did a version 2.0-alpha-6-SNAPSHOT for the
maven-archetype-plugin get into Nexus and how do I get rid of it?
Another one is the maven-help-plugin; it wants to use version
2.2-SNAPSHOT which isn't available.
Please help! This is driving me nuts; I'm tired of typing everything
out the long way, e.g.:
mvn org.apache.maven.plugins:maven-help-plugin:2.1.1:help
instead of
mvn help:help

I'm not sure if that's exactly what it is, but it sounds similar.
I just removed "Apache Snapshots" and "Codehaus Snapshots" from my
Public Repositories group and now all is well, hooray!
Now tell me, why would Nexus put these snapshot repos in my Public
Repositories group by default? That's just insane, or am I missing
something? (Sorry, this complaint should be on the Nexus list).

Hmm, I don't see a JBoss repo in my Nexus, however I do see an Apache
Snapshots. I shouldn't have that in there should I? Hmm, there's
also Codehaus Snapshots. I don't think I want that either.
General question about plugins: Is it true that running a plugin
(e.g., mvn help:help) will choose the latest version even if it is a
snapshot? That seems kind of, I don't know, not good. Why not let
the developers of the plugin have to specify a version to run for a
snapshot, and let the rest of us run the latest _release_ version?

Sounds familiar.
I have seen these problems occur because of inclusion of the JBoss maven
repo.
In my case, I fixed it by not proxying the entire jboss repo but only
there releases.
