alice-teacher Alice 3 and Netbeans "root directory not set" error

[Donald Slater]

Edward,
I am guessing that you are trying to create an executable .jar file. This is currently not possible, or I have not yet figured out a solution to the problem you are now wrestling with.

We are working on a player that will allow you to run Alice Projects without needing Alice, but I cannot now say when it will be ready.

I am sorry.
