Unable to build Adhoc distribution from command line - appcelerator

Question

I am trying to script the IPA creation process for Appcelarator Alloy project with grunt using the grunt-appc-cli plugin.
My target config looks like below:
'dist-prod': {
'command': "run",
'args': [
'-p', 'ios',
'-T', 'dist-adhoc',
'-R', '<Dev Cert Name>',
'-P', '<Provisioning Profile UUID>',
'-O', './dist/prod/',
'--log-level', 'trace'
]
},
Running this grunt target gets stuck at following:
>> [INFO] JavaScript files need to be encrypted
>> [INFO] Creating Xcode project
>> [TRACE] Removing pre-compile phase
>> [TRACE] Adding 3 native module libraries
>> [TRACE] No extensions to add
>> [INFO] Creating Entitlements.plist
>> [INFO] Creating Info.plist
>> [INFO] Disabling ATS
>> [INFO] Creating main.m
>> [INFO] Creating Xcode config files
>> [INFO] Copying Titanium libraries
>> [INFO] Copying Titanium iOS files
>> [TRACE] Skipping Classes/ApplicationRouting.m, it'll be processed later
After a while I have to Ctrl+C to kill without generating an IPA.
Any pointers to debug this issue?
**** More Info ****
I tried to run the appc run cmd directly and end up with the following error message:
$ appc run -p ios -T dist-adhoc -R "<Dev Cert Name>" -P "<Provisioning Profile UUID>" -O ../Svc --log-level trace
[ERROR] ** BUILD FAILED **

Make sure you are running on Xcode 7.3.1 and above and Titanium SDK 5.4 GA - That should address your problem.

If you still see the problem with the above environment, please provide more details in the JIRA ticket.
