Try to run
   mvn *-U* archetype:create -DgroupId=com.mycompany.app -DartifactId=myApp

The "-U" force plugin updates, thismay solve this issue.

Hi all,

I'm sure this is not a cutting edge question.
I've just downloaded and installed Maven.

1)
Well, I simply followed the Installation instructions from page
http://maven.apache.org/download.html#installation


       Windows 2000/XP

  1. Unzip maven-2.0.3-bin.zip to the directory you wish to install
     Maven 2.0.3. These instructions assume you chose C:\Program
     Files\Apache Software Foundation\maven-2.0.3
  2. Add the bin directory to your path, by opening up the system
     properties (WinKey + Pause), selecting the "Advanced" tab, and the
     "Environment Variables" button, then editing the PATH variable in
     the user variables. eg. "C:\Program Files\Apache Software
     Foundation\maven-2.0.3\bin";%PATH%
  3. In the same dialog, make sure that JAVA_HOME is set to the
     location of your JDK, eg. C:\Program Files\Java\jdk1.5.0_02
  4. Run mvn --version to verify that it is correctly installed.


And then I try the first command of the Maven Getting Started Guide
(http://maven.apache.org/guides/getting-started/index.html):

2) But here is what I get:

3) What should I do? Is it a configuration problem? How to install locally the plug-in? 

Thanks for any help,

Xavier.
