title: unable to download artifact from nexus repo
body: <p>I am using a nexus repo in a linux system which downloads missing artifacts for me in my windows system when i build my project, by using:</p>
  
  <pre><code>mvn install command
  </code></pre>
  
  <p>The artifacts are downloaded by my nexus repo from a remote repo which is mapped to the nexus repo.</p>
  
  <p>This connection between the nexus repo set up in linux system and the remote repo used to work earlier and thus I used to get all the required artifacts for my maven build automatically when i used to build my project using maven.</p>
  
  <p>But due to some reasons the nexus repo in linux is not downloading artifacts from the remote repo.I want this connection to happen so that i could get the required artifact say, tomcat-catalina-7.0.16.jar,downloaded from the remote repo.</p>
  
  <p>I am new to nexus..so may be I would not have been able to explain my problem properly or would have been technically unsound in my question.But I eagerly want to solve my problem.So please if any one could help, please do.</p>
  
  <p>hi, i checked nexus.log and found the following exception while mvn install command was running and when nexus was trying to download the missing tomcat-catalina-7.0.16.jar artifact from the remote repo:</p>
