title: Error resolving version for plugin 'org.codehaus.mojo:maven-war-plugin' from the repositories
body: <p>I am using eclipse Indigo Service Release 2 with <em>JBoss</em> tools installed and created a Seam Web project with Maven integration selected. After the project is created, I got this error in my pom.xml file, does anybody know how to resolve it? thanks</p>
  
  <pre><code>Error resolving version for plugin 'org.codehaus.mojo:maven-war-plugin'
  from the repositories [local (C:\Users\Jon\.m2\repository), 
  jboss-public-repository-group 
  (https://repository.jboss.org/nexus/content/groups/public/),
  central (http://repo1.maven.org/maven2)]: 
  Plugin not found in any plugin repository
  </code></pre>
  
  <p>I also tried to create a new Seam web project with Maven integration again, this is the step I followed: <a href="http://docs.jboss.org/tools/nightly/trunk/en/seam/html/create_mavenized_seam.html#create_mavenized_project" rel="nofollow">http://docs.jboss.org/tools/nightly/trunk/en/seam/html/create_mavenized_seam.html#create_mavenized_project</a>
  After the project is created, I got these error in eclipse api, all are related to pom.xml (with a red sign)</p>
  
  <pre><code>Missing artifact org.jboss.tools:Maven2:war:0.0.1-SNAPSHOT

  <p>No sure why I got different error each time, I use eclipse indigo new version 64big downloaded here:<a href="https://www.eclipse.org/downloads/packages/eclipse-ide-java-ee-developers/indigosr2" rel="nofollow">https://www.eclipse.org/downloads/packages/eclipse-ide-java-ee-developers/indigosr2</a>
  and add jboss tools from Marketplace, with Jboss server and Seam famework. Based on the error, do I have install any plugins? it is so confusing, because I got different error each time. </p>
