I think that AbstractMethodError always means either mismatched scala version
or out of date class file.

Hello all,
I am trying to launch a lift web app on my computer, but trying to use
Snapshot 2.0 instead of 1.0 (which seems to have some problems with
Scala 2.7.7).
I have taken the following steps :
- tried to create a lift blank app with 2.0-snapshot, adapting the
archetype:generate command from the book as required
Try to show the complete command. Or look in the ML for commands that
work with 2.0-SNAPSHOT
- once that is done, I modify the version of scala in my pom.xml
- then I type 'mvn jetty:run'
- somehow maven still downloads *both* the 2.7.1 and 2.7.7 versions of
scala, and I get the warning that both of them exist
This sounds bad
when trying to look at the webpage on localhost:8080, I am given the
following error :
Request for / failed net.liftweb.http.SessionMaster$.mailbox_
$eq(Lscala/actors/MessageQueue;)V

I have not posted the whole stacktrace, but will do so if necessary.
Googling for this error gives me messages that are very old, and they
don't apply to me.
You may have old code laying around. If code mysteriously fails, mvn
clean is your friend. Try; mvn clean jetty:run
