[Lift] LiftBook: Maven example does not work

[Hadmut]

Hi,

I am just starting with Lift and exploring it (coming from C,C++,
Ruby, Rails,...) . I started with the first example in the LiftBook
and ran into an error message:

% mvn archetype:generate -U -DarchetypeGroupId=net.liftweb -
DarchetypeArtifactId=lift-archetype-blank -DarchetypeVersion=1.0 -
DremoteRepositories=http://scala-tools.org/repo-releases -
DgroupId=demo.helloworld -DartifactId=helloworld -Dversion=1.0-

(the -e switch gives me a backtrace, but is not helpful at all)


How could I find what's the problem? Is there any strategy to debug?

I was surprised how many files maven needs to download from Internet
when started for the first time. I don't think that it is a good idea
to use a tool of this complexity that needs to download that many
different parts from internet. I do not consider using such tools as a
good idea.

Isn't that a no-go for offline development?

Hadmut

Yeah... something broke in Maven-land.  The example worked and stopped working over the weekend (there was another post about this).

Indrajit or DavidB or some other Maven guru... what happened?

How can you choose such an unreliable tool for something like Lift?

It should be restricted to tools that can be completely packaged and
put into software archives.

Such problems do disqualify Lift completely for any use in production
environments.

-DremoteRepository=... should be -DarchetypeRepository=... I think

Yes, but why did the particular invocation that's been working for more than a year suddenly stop working.  This is problematic.

Um... what unreliable tool are you talking about?  If you're going to complain about Maven, don't.  The discussion comes up from time to time and you know, we're not having it again.  There are other options if you don't like Maven.
 

It should be restricted to tools that can be completely packaged and
put into software archives.

What are you proposing?
 

Such problems do disqualify Lift completely for any use in production
environments.

Lift has been successfully using Maven and Maven repositories very successfully for more than 3 years.

If you want to use sbt with Lift, you can clone the repository at http://github.com/dpp/lift_sbt_prototype

There are also Ant/Ivy, Buildr, and even Graddle build formulas.  http://jeppenejsum.wordpress.com/2010/04/16/lift-quick-start-look-ma-no-maven/

The (new) wiki has articles about how to use 4 different build systems with Lift: https://www.assembla.com/wiki/show/liftweb/Getting_Started :)

[Mads Hartmann Jensen]

Of course 1 of them haven't been written yet and two of them rely on the maven generate command. My bad ;)

Good question, perhaps a new maven-archetype-plugin upstream. That is beyond my maven-fu, but I can pick out arguments that differ from the formula I know works ;-)

[David Bernard]

Like Ross suggest I suppose it's a change in the since the version 2.0-alpha-5 of the maven-archetype-plugin.

remoteRepository is replaced by archetypeRepository

mvn archetype:generate -U -DarchetypeGroupId=net.liftweb -DarchetypeArtifactId=lift-archetype-blank -DarchetypeVersion=1.0 -DremoteRepositories=http://scala-tools.org/repo-releases -DgroupId=demo.helloworld -DartifactId=helloworld -Dversion=1.0-SNAPSHOT

or  more reliable in the future using the fullname of the goal

mvn org.apache.maven.plugins:maven-archetype-plugin:2.0-alpha-5:generate -U -DarchetypeGroupId=net.liftweb -DarchetypeArtifactId=lift-archetype-blank -DarchetypeVersion=1.0 -DremoteRepositories=http://scala-tools.org/repo-releases -DgroupId=demo.helloworld -DartifactId=helloworld -Dversion=1.0-SNAPSHOT

Who do I have to talk to to get them Maven Archetype people not to screw up piles and piles of command lines?

http://jira.codehaus.org/browse/ARCHETYPE
2.0-alpha-5 was released 2010/04/23
2.0-alpha-4 was released 2008/09/28

[David Pollak]

David,

Thanks.  I've sent email off to Jason (the owner of the project) asking him to reverse the breaking changes.  Anybody else who has influence over Jason or the Maven community... please let everyone know that this is a significant issue.

We'll do our best to update the various documents we've got floating around about Lift, but it's something that's going to take more than a week and we've got a DZone article about Lift coming out this week (aka it's a seriously suboptimal situation.)

Thanks,

David
