title: ArtifactTransferException in Eclipse project when importing the Examples
body: <p>I'm trying to run some of the Netty example projects. After importing the Maven project, Eclipse reports the following problem:</p>
  <pre><code>ArtifactTransferException: Could not transfer artifact io.netty:netty-tcnative:jar:${os.detected.classifier}:1.1.33.Fork2 from/to central (http://repo1.maven.org/maven2): Illegal character in path at index 96: http://repo1.maven.org/maven2/io/netty/netty-tcnative/1.1.33.Fork2/netty-tcnative-1.1.33.Fork2-${os.detected.classifier}.jar
  </code></pre>
  <p>Things I've tried after researching related questions:</p>
  <ul>
  <li>Deleting the lastupdated files (seems to be a common cause of ArtifactTransferExceptions)</li>
  <li>Manually adding the os-maven-plugin to the eclipse plugins folder <a href="http://ArtifactTransferException:%20Could%20not%20transfer%20artifact%20io.netty:netty-tcnative:jar:$%7Bos.detected.classifier%7D:1.1.33.Fork2%20from/to%20central%20(http://repo1.maven.org/maven2):%20Illegal%20character%20in%20path%20at%20index%2096:%20http://repo1.maven.org/maven2/io/netty/netty-tcnative/1.1.33.Fork2/netty-tcnative-1.1.33.Fork2-$%7Bos.detected.classifier%7D.jar" rel="nofollow noreferrer">as described here</a></li>
  <li>Cleaning the project</li>
  <li>Deleting the eclipse project and re-importing</li>
  </ul>
  <p>What should I try next (or am I even going down the right path for running the Netty examples)?</p>
