title: MVN install, cannot find artifact in local repository
body: <p>I did <code>mvn install</code> and get this error message 
  <code>Failed to execute goal on project core: Could not resolve dependencies for project test:core:jar:2.0.1-SNAPSHOT: Could not find artifact lib-net:lib-net:jar:1.0.8 in central (http://repo.maven.apache.org/maven2)</code></p>
  
  <p>this dependency is a Project of mine, which is available in the local repository ~/.m2</p>
  
  <p>so I tried <code>mvn install -o</code> to force maven to use my local repository, and I get this </p>
  
  <p><code>Failed to execute goal on project core: Could not resolve dependencies for project test:core:jar:2.0.1-SNAPSHOT: The repository system is offline but the artifact lib-net:lib-net:jar:1.0.8 is not available in the local repository.</code></p>
  
  <p>I tried to delete my local repository and install everything again, but it doesn't solve my problem!</p>
  
  <p>Any sugestions?</p>
