Maven and elevator with scala 2.8: is there no mapping mapper?

Question

A newbie question, since I'm not ready to use maven at all.

I am trying to use scala + lift using scala 2.8, the environment is a win7 field, if that matters.

I am creating 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 write to my new project and execute:

 mvn jetty:run 

After several downloads, I get an error as shown 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?

Answer 1

I created the same project using the mvn archetype:generate command that you provided, but I could not reproduce your problem. The artifact lift-mapper-2.0-scala280-SNAPSHOT.jar definitely in the scala snapshot storage 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 due to a failed CHECKSUM check, but it worked.

Try again.
