I really should have known better, but that was what I was missing. I
hadn't yet set the C:\Swarm-2.2-java\bin\ in my PATH section of "User
Variables" under the Windows Environmental Variables. To be safe, I has
also added a new SWARMHOME path in the User Variables as well.
It didn't work right away in Eclipse, but after starting a new project
and importing the File System of stupidModel_1 (following step 6, a-f
of the tutorial) and running it by following step 7a of the tutorial it
all worked.
Some times you just need an extra eye to point out the simple mistakes we can overlook.
