title: Unable to commit via Subclipse+SVNKit due to no valid credentials
body: <p>I recently upgraded several packages on my Ubuntu 12.04 system, and now Subclipse is unable to commit, giving me the error:</p>
  
  <pre><code>svn: E170001: Commit failed (details follow):
  svn: E170001: Negotiate authentication failed: 'No valid credentials provided'
  </code></pre>
  
  <p>This is <a href="https://stackoverflow.com/questions/7904216/subversive-reject-credentials">similar</a> to a problem I had with Subversion, but I believe due to a different cause.</p>
  
  <p>Prior to the upgrade, I was using Subclipse with the JavaHL adapter, which worked just fine. After the upgrade, Eclipse complained:</p>
  
  <pre><code>Failed to load JavaHL Library.
  These are the errors that were encountered:
  no libsvnjavahl-1 in java.library.path
  no svnjavahl-1 in java.library.path
  no svnjavahl in java.library.path
  java.library.path = /usr/lib/jvm/java-6-openjdk-amd64/jre/lib/amd64/server:/usr/lib/jvm/java-6-openjdk-amd64/jre/lib/amd64:/usr/lib/jvm/java-6-openjdk-amd64/jre/../lib/amd64:/usr/java/packages/lib/amd64:/usr/lib/jni:/lib:/usr/lib
  </code></pre>
  
  <p>I then used Eclipse's updater to upgrade Subclipse itself to the most recent 1.10 and reinstall the JavaHL component, but that failed to solve the problem. However, it did allow me to install the SVNKit component, which I did, and switched to via Team->SVN. That solved the "Failed to load JavaHL Library." error, but just replaced it with the "No valid credentials" error.</p>
  
  <p>I've confirmed the credentials I'm using a still valid, and I can login to the serve with them. How do I fix this?</p>
