Lift Maven Archetype

[Senthil]

When I try to run jetty, I am getting the following error. I have
created the project as specified in Wiki using maven archetype-basic

E:\myworkout>mvn -e jetty:run

What is the content of E:\myworkout\pom.xml ?

[Indrajit Raychaudhuri]

Senthil,

Looks like the section for maven-jetty-plugin is incorrect in your
project descriptor (E:\myworkout\pom.xml).

At the least, it should be having something like:
<plugin>
<groupId>org.mortbay.jetty</groupId>
<artifactId>maven-jetty-plugin</artifactId>
<version>6.1.25</version>
</plugin>

Specifically, the <groupId/> element is mandatory in the particular case
of jetty (since it's not a Maven distributed plugin).

As David said, please share the way you got this pom.xml (command, wiki
etc.)

Seems like I have the same problem: I have this in my pom:

<plugin>
<groupId>org.mortbay.jetty</groupId>
<artifactId>maven-jetty-plugin</artifactId>
<version>6.1.25</version>

<configuration>
<contextPath>/</contextPath>
<scanIntervalSeconds>5</scanIntervalSeconds>
</configuration>
</plugin>

(it was 6.1.24, I changed it back and forth to 6.1.25), and all I see
is the following when I run mvn -e jetty:run:

[ERROR] No plugin found for prefix 'jetty' in the current project and
in the plugin groups [org.apache.maven.plugins, or

g.codehaus.mojo] available from the repositories [local (C:\Users

Reading the article referenced, I checked out settings.xml in my .m2
directory - there's none.
So I found settings.xml in maven/conf directory, copied it over to
my .m2 - did not help. Looking into this file, I got a feeling it is
just a stub.

So probably the question is - who and how is supposed to build teh
right settings.xml?

Thanks,
-Vlad

Are you using Maven 3? If so, try:
http://maven.apache.org/settings.html#Plugin_Groups

[Vlad Patryshev]

Thank you! It helped.
