Kepler

I'm getting an error when trying to import the actor created with the revamped (for suites) hello-world tutorial into kepler-1.0. I thought this worked, albeit without the use of suites, when we released 1.0...

My procedure (roughly) and resultant messages:

cd kepler.modules/build-area
ant clean-cache
ant change-to -Dsuite=kepler-1.0
ant make-module-suite -Dname=hello-world
ant change-to -Dsuite=hello-world
cd ../hello-world/src
mkdir org
cd org
[create the HelloWorld actor java file from the website]
cd ../../../build-area/
ant run
instantiate HelloWorld actor
Right click on actor, Export to Kar, saving class file
Quit Kepler

ant clean-cache
ant change-to -Dsuite=kepler-1.0
ant run
File => Import Archive (the hello world actor)
Dialog (that stretches beyond the length of one monitor): The id of the actor or workflow you are trying to import already exists [snip] Would you like to change the id of your actor to the next available id?" (Click Yes)
Error: Error inserting the kar file into the cache: Id already exists in the cache: Error creating KARCacheObject: lib/jar/org.helloworld.HelloWorld.jar (No such file or directory).
