Every now and then when i make a change to the pom of a WTP project the maven classpath container becomes empy. There are no error messages and mvn compile on the command line works fine. The only way to get the classpath back again is to

1 Disable and enable maven on the project
2 Close and open the project

Often we have to repeat this a couple of times before everything pops back to normal again. IAM works perfectly except for this little annoying detail. Any suggestions?

Ganymede IAM 0.10

I am looking at an Ecplise that has this problem right now. There are no error messages in the Error log that seem relevant. I tried clearing it, restarted tomcat and it remains empty.

Now, I was a bit unclear in my previous post. The Maven classpath container as it appears in the project looks quite healty, but what gets written to Tomcat's server.xml is missing all Maven dependencies. I included a snippet from Tomcat's server.xml (which is under Eclipse control). Normally the virtualPath attribute contains a long list of paths pointing to my local maven repository.

So it looks like IAM's got it right but somehow it doesn't make it all the way to server.xml.


Snippet from server.xml:


<Context docBase="C:\Projects\FF\my-project\src\main\webapp" path="" reloadable="true" source="org.eclipse.jst.j2ee.server:my-project">
<Resources className="org.eclipse.jst.server.tomcat.loader.WtpDirContext "
virtualClasspath=" C:\Projects\FF\my-project\target\test-classes;C:\Projects\FF \my-project\target\classes;C:\Projects\FF\my-common\target\t est-classes;C:\Projects\FF\my-common\target\classes "/>
<Loader className="org.eclipse.jst.server.tomcat.loader.WtpWebappLoader " useSystemClassLoaderAsParent="false"
virtualClasspath=" C:\Projects\FF\my-project\target\test-classes;C:\Projects\FF \my-project\target\classes;C:\Projects\FF\my-common\target\t est-classes;C:\Projects\FF\my-common\target\classes "/></Context>
<Context debug="1"
docBase="C:\Projects\FF\backoffice\src\main\webapp" path="/backoffice" reloadable="true" source="org.eclipse.jst.j2ee.server:backoffice">
