The container 'Web App Libraries' references non existing library 'C:\work\WebRoot\WEB-INF\lib\google-collections-1.0-rc4.jar'
<p>I have seen similar bugs with "Maven Libraries" but this is for "Web App Libraries".</p>

<p>This is the story: I had the jar in question that I added to the application as an <code>External Jar</code> on the location specified. Then I removed it from the Build Path and deleted it from <code>C:\workWebRoot\WEB-INF\lib\google-collections-1.0-rc4.jar</code>.</p>

<p>On opening Eclipse I get the error: <code>The container 'Web App Libraries' references non existing library 'C:\work\WebRoot\WEB-INF\lib\google-collections-1.0-rc4.jar'</code></p>

<p>I went to <code>Project -&gt; Properties -&gt; Build Path</code> and looked at both jars and <code>Web App Libraries</code>... this jar is not in the list of jars.</p>

<p>I tried to right-click and <code>Refresh</code> the project.</p>

<p>I tried to <code>Clean</code> and <code>Build</code> the project again.</p>

<p>None of it worked.</p>

<p>How can I tell Eclipse to stop looking for this jar!?</p>
