title: EhCache POM is misbehaving
body: <p>Last month I asked <a href="https://stackoverflow.com/questions/8954093/maven-error-when-resolving-dependency">this</a> question because I couldn't get the EhCache jar to pull down into my local Maven cache using the M2E Eclipse plugin.</p>
  
  <p>Now, I am trying to convert several EhCache/Terracotta POM files into Ivy XML files (using the <code>IvyConvertPom</code> task (which works perfectly fine for every other POM in my local repository - and there are <em>hundreds</em>) and it is choking, stating:</p>
  
  <blockquote>
    <p>impossible convert given pom file to ivy file: java.io.IOException: Impossible to load parent for file:/C:/Users/myUser/jars/net/sf/ehcache/ehcache-terracotta-root/2.5.0/ehcache-terracotta-root-2.5.0.pom. Parent=org.terracotta.forge#forge-parent;2.3 from=C:/Users/myUser/jars\net\sf\ehcache\ehcache-terracotta-root\2.5.0\ehcache-terracotta-root-2.5.0.pom to=C:/Users/myUser/jars\net\sf\ehcache\ehcache-terracotta-root\2.5.0\ivy.xml<br>
    Could not find artifact for C:/Users/myUser\jars\net\sf\ehcache\ehcache-terracotta-root\2.5.0\ehcache-terracotta-root-2.5.0.pom</p>
  </blockquote>
  
  <p>This is happening for all of the following EhCache/Terracotta artifacts:</p>
  
  <ul>
  <li><code>net\sf\ehcache\ehcache-terracotta\2.4.7\ehcache-terracotta-2.4.7.pom</code></li>
  <li><code>net\sf\ehcache\ehcache-terracotta\2.5.0\ehcache-terracotta-2.5.0.pom</code></li>
  <li><code>net\sf\ehcache\ehcache-terracotta-root\2.4.7\ehcache-terracotta-root-2.4.7.pom</code></li>
  <li><code>net\sf\ehcache\ehcache-terracotta-root\2.5.0\ehcache-terracotta-root-2.5.0.pom</code></li>
  </ul>
  
  <p>I'm not sure if this issue is related to the issue I had last month, or if the developers over at EhCache just have a non-standard way of writing their POMs, but this is twice now where Maven (<code>IvyConvertPom</code> uses Maven XSLT under the hood) has choked on doing something with their jars.</p>
  
  <p>Does anything jump out at anybody as being obvious? Otherwise I have to debug Ivy code, which sounds like a <em>painful</em> way to wrap up a Wednesday. I'll do it if I have to, but thought I'd ask here first in case I was missing something glaring.</p>
  
  <p>Thanks in advance!</p>
