To validate the application.yml configuration file, open a command-line interpreter in the bin folder of the cagw-util tool and run the following command.

cagw-util validate-yaml <APPLICATION_YML>

Where <APPLICATION_YML> is the path of the application.yml configuration file – for example:

$ cagw-util validate-yaml application.yml
 
Validating YML File...
 
YAML File is Valid but only in syntax, content has not been evaluated.

When detecting any error, the tool returns detailed information – for example:

$ cagw-util validate-yaml application.yml
 
Validating YML File...
