title: Problems uploading jar artifact to hosted maven repository in nexus OSS 3.0.0-03
body: <p>I've just installed OSS 3.0.0-03 on a linux box and it is working well for proxying to Maven central etc. I've created a hosted repository for third party jars but I'm having problems uploading the jar to the repository.</p>
  
  <ol>
  <li>Is there any way to do this from the UI like there was in OSS 2.13? </li>
  <li>I've tried using Maven deploy file goal but it fails with a socket write error:</li>
  </ol>
  
  <p>Failed to execute goal org.apache.maven.plugins:maven-deploy-    plugin:2.7:deploy-file (default-cli) on project standalone-pom: Failed to deploy artifacts: Could not transfer artifact com.stream:StreamLib:jar:7.3 from/to nexus (<a href="http://kamino:8081/nexus/repository/maven-thirdparty" rel="nofollow">http://kamino:8081/nexus/repository/maven-thirdparty</a>): Software caused connection abort: socket write error</p>
  
  <p>I've checked my firewalls and can see no issues there. The command line I am using is</p>
  
  <p>mvn deploy:deploy-file -DgroupId=com.stream -DartifactId=StreamLib -Dversion=7.3 -DgeneratePom=true -Dpackaging=jar -DrepositoryId=nexus -Durl=<a href="http://kamino:8081/nexus/repository/maven-thirdparty" rel="nofollow">http://kamino:8081/nexus/repository/maven-thirdparty</a> -Dfile=StreamLib.jar -e</p>
  
  <p>My maven settings.xml has a 'nexus' server entry for kamino with my admin username and password.</p>
  
  <p>Thanks</p>
