maven and lift using scala 2.8 : lift-mapper missing? - maven-2

Question

Newbie question since I'm not up to speed using
maven at all.
I'm trying to use scala + lift using scala 2.8, environment
is a win7 box if that matters.
I create a basic project using:
mvn archetype:generate -U -DarchetypeGroupId=net.liftweb -DarchetypeArtifactId=lift-archetype-basic -DarchetypeVersion=2.0-scala280-SNAPSHOT -DarchetypeRepository=http://scala-tools.org/repo-snapshots -DremoteRepositories=http://scala-tools.org/repo-snapshots -DgroupId=com.liftworkshop
-DartifactId=todo -Dversion=1.0-SNAPSHOT
So far so good, but then, I try to cd into my new project
and do:
mvn jetty:run
I after quite a few downloads end up with a error like below:
[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------
[INFO] Failed to resolve artifact.
Missing:
----------
1) net.liftweb:lift-mapper:jar:2.0-scala280-SNAPSHOT
Try downloading the file manually from the project website.
Then, install it using the command:
mvn install:install-file -DgroupId=net.liftweb -DartifactId=lift-mapper -D
version=2.0-scala280-SNAPSHOT -Dpackaging=jar -Dfile=/path/to/file
Alternatively, if you host your own repository you can deploy the file there:
mvn deploy:deploy-file -DgroupId=net.liftweb -DartifactId=lift-mapper -Dve
rsion=2.0-scala280-SNAPSHOT -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -Dr
epositoryId=[id]
Path to dependency:
1) com.liftworkshop:todo:war:1.0-SNAPSHOT
2) net.liftweb:lift-mapper:jar:2.0-scala280-SNAPSHOT
----------
1 required artifact is missing.
for artifact:
com.liftworkshop:todo:war:1.0-SNAPSHOT
from the specified remote repositories:
scala-tools.snapshots (http://scala-tools.org/repo-snapshots),
scala-tools.releases (http://scala-tools.org/repo-releases),
central (http://repo1.maven.org/maven2)
Any ideas?

I created the same project using the mvn archetype:generate command you provided but I couldn't reproduce your problem. The lift-mapper-2.0-scala280-SNAPSHOT.jar artifact is definitely in the scala snapshots repository and Maven downloaded it:
...
1619K downloaded (lift-mapper-2.0-scala280-SNAPSHOT.jar)
[WARNING] *** CHECKSUM FAILED - Checksum failed on download: local = '0c857e2c5de9d5cabb7c972e519528606f19697b'; remote = 'a258cf7d7a49a8d7163d499da06a4d1e231a78e0' - RETRYING
Downloading: http://scala-tools.org/repo-snapshots/net/liftweb/lift-mapper/2.0-scala280-SNAPSHOT/lift-mapper-2.0-scala280-SNAPSHOT.jar
1619K downloaded (lift-mapper-2.0-scala280-SNAPSHOT.jar)
As you can see, Maven had to retry the download because of a failed CHECKSUM check but it worked.
Just try again.
