[m2] Strange Build Error

["Allison, Bob" <ro...@qwest.com>]

I am experimenting with a directory archiver for plexus, and built a new
snapshot version of the component.  When I did a "mvn install" in that
directory, the install placed the jar where I expected it:

[INFO] [install:install]
[INFO] Installing
/net/home/allisord/src/plugins/plexus-archiver/target/plexus-archiver-1.
0-alpha-4-SNAPSHOT.jar to
/home/allisord/.m2/repository/org/codehaus/plexus/plexus-archiver/1.0-al
pha-4-SNAPSHOT/plexus-archiver-1.0-alpha-4-SNAPSHOT.jar


The strange part is when I went to compile against the component.  I
changed the project to declare a dependency to
org.codehaus.plexus:plexus-archiver:1.0-alpha-4-SNAPSHOT (instead of
1.0-alpha-3) and got the following:

[allisord@qadev21 rpm]$ mvn -X compile
