The database configured in idempiere.properties apparently does not exist. 

Remove the file F:\idempiere\idempiere.properties and run the ModelGenerator again, and then check the settings of the database.

Not working too

I am not sure of Anderson's proposed solution, I have not tried it.

We experienced the same problem here on two different developer's machines.It was strange, in that it worked in the beginning, but then stopped working.

Since I did not find a solution to this problem (I had to re-materialize my workspace), and it is probably a good practice anyway, the workaround is as follows:

• After materializing your workspace, and your workspace is stable, and you are able to run the model generator class:

• Take a backup of your workspace.

• In Linux, use tar to make a tar archive (find attached a useful script, for this purpose). In Windows, use robocopy, example "C\workspace\from" ""C\workspace\backup" /copyall /r:3 /w:1 /zb /e

• If you experience this kind of error again, restore back to stable workspace.

• I have found you need to restore back to the same folder name, but I am not sure about this.

• Be sure to update the snapshot of your workspace on a regular basis, I have found it to be invaluable.

I would be curious to know if anyone finds the root cause of this problem, it does cause a headache.

Run sign.database.build

Thanks, I'll give it a try, if I experience the problem again.
