[flexcomponents] Cannot export

[dorkie dork from dorktown]

Is there a reason I'm getting a warning in my Flex Ant build project like
this?

Severity    Description    Resource    In Folder    Location    Creation
Time    Id
1    java.io.FileNotFoundException: JAR entry flexTasks.tasks not found in
C:\Documents and Settings\Judah\My Documents\Flex Builder
2\HTMLFrame\flexTasks\lib\flexTasks.jar    flexant-build.xml    HTMLFrame
line 4    March 22, 2007 8:44:43 PM    12396

Here is line 4:
   <taskdef resource="flexTasks.tasks"
classpath="${basedir}\flexTasks\lib\flexTasks.jar" />

I'm pretty sure it points to the correct path. The build process seems to
run.
