Inject variables with a secret value

[Jurn van Mieghem]

Currently I am updating my plans to start using bamboo-yaml specs. However I do have variables I use in a lot of plans and want to create an `inject-variables`-task to import this list. As this list contains usernames and passwords I'd like to use the Bamboo encryption for these variables. However the injection seems to work, but not the decryption on Bamboo's end. 

Can someone help me out or tell me what I do wrong.

task:

- inject-variables:
   file: variables.conf
   scope: LOCAL
   namespace: inject

inject variables file;

env_password="BAMSCRT@RANDOMSTRING"
env_username="user"

Therefor I need to use `${bamboo.inject.env_password}` in the script later on. But it seems to pass along the string "BAMSCRT@RANDOMSTRING" instead of the decrypted password
