I have a simple JET transform that works fine when I run it inside a
"child" Eclipse Application for debugging (for some reason I don't fully
understand it doesn't run in my development instance). Now I want to
deploy the transform. I did:

1. Export deployable plugin (into a folder)
2. Closed the original project to prevent interference.
3. Took the create JAR, put it in "Dropins"
4a. The plugin gets loaded eventually, but trying to run transform gives
me an "Internal Error" caused by an "IllegalArgumentException" (stack
trace below, it's the same in all cases.

Since that didn't work, remove the plugin from "Dropins" and restarted
Eclipse.

4b. Added the folder I export to, to the JET Transforms preferences, and
ran the transform again. Same effect as above.

The stack trace I get for the error is this:
java.lang.IllegalArgumentException

at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)

Any ideas what I'm doing wrong or what could be causing this error?

Thanks,
Jochen

Jochen:

This particular IllegalArgumentException is thrown if the Transformation
Input path on the transformation config does not map to a real-life file.

Obviously, a better error message is in order. I have submitted bug 251773:
