Batch runs called with --targetdacpac failing to find file on batch nodes

[jormdav]

Experimenting with the --targetdacpac batch run commandline switch, I'm able to confirm that an .sbm file is getting properly generated on our client, and pushed to the batch nodes (alongside the platinum dacpac file and .cfg targets file) .

However, the batch job exits early with exit code -728 - A Target Dacpac file was specified but could not be located at 'C:\scrap2\npr\MyTargetDacPac.dacpac'

The "C:\scrap2..." path was the value supplied to the --targetdacpac file, so I wouldn't expect that exact path to be mirrored on the batch node. However, I'm wondering if this dacpac file is even needed on the batch nodes at all, since the .sbm file was already created from it?

I hacked in this line to BatchManager.CompileCommandLines(), which otherwise allowed it to process successfully (against the same database that the targetdacpac was extracted from, at least):

threadCmdLine.DacPacArgs.TargetDacpac = null;

A logging note -- though the batch job / task failed, the -728 error only appeared in the console log and stdout.txt files -- the Errors.log and stderr.txt were empty.
