Running the entire deployment on the command line simply returns a "Completed with error".(Again, a deployment where I simply change the DCR's name from "error-test" to "erro-test" passes w/o problems.)
File a bug but there may be nothing IWOV can do about it. Often the app needs to grep through the output from something else (like JDBC) and not always gets passed an error code. So It flags that the deployment completed but it saw the word error. FWIW, there have been a few cases like this. WFT acted funny when a branch was names default (available_templates uses default and regex matched), so it is not uncommon.
