Before I cleaned everything and reinstalled, the log contained these
three items (multiple times):

---------------- .log entries --------------

!ENTRY org.eclipse.ui 4 0 2011-03-09 20:05:05.798
!MESSAGE Unable to create editor ID
org.eclipse.ant.ui.internal.editor.AntEditor: No editor descriptor for
id org.eclipse.ant.ui.internal.editor.AntEditor

and

!SUBENTRY 2 org.eclipse.ui 4 4 2011-03-09 20:05:11.139
!MESSAGE Could not create view: org.eclipse.ant.ui.views.AntView

and

!ENTRY org.eclipse.core.resources 4 2 2011-03-09 22:59:23.369
!MESSAGE Problems occurred when invoking code from plug-in:
"org.eclipse.core.resources".
!STACK 1
org.eclipse.debug.core.DebugException: Launch configuration type id
"org.eclipse.ant.AntBuilderLaunchConfigurationType" does not exist.
Possible causes:
        Missing specification of a launch type (missing plug-in)
        Incorrect launch configuration XML

---------------------------

After cleaning and reinstalling, the log is basically empty.  So the
above errors my be red herrings.   I tried creating a new user and
running eclipse, but no luck (no ant preferences, no ant builder, no ant
editor).  I tried installing Sun's jdk, and got the same result.

I tried to find a difference between my machine's eclipse installation
and another f14 installation (with working ant features), without luck.
The /usr/lib64/eclipse tree looks the same regarding ant jars.

It seems like the ant jars are not being recognized on my machine.
Possibly a classpath issue.  But I can't see the difference between the
two machines.
