Hello,

Greetings.

I would like to know where the variables listed in "Variables wizard" are defined? Is there a configuration page in the installer?

How to add/remove/modify variables in the wizard?

Thanks,
Nazul

Hi Nazul,

How variables are declared and used is explained in
https://wiki.eclipse.org/Eclipse_Oomph_Authoring#Declaring_and_Using_Variables .

If you describe in more detail what exactly you're trying to achieve I can possibly give more specific advice ;-)

Cheers

You've defined user.name to have the value ${scope.user.name} and scope.user.name is an induced variable that will have the value of the name property of the User scope. As such, even if the variable user.name is used in some task (as ${user.name}) it will already have value defined and will not be prompted. You could change your definition so that ${scope.user.name} is the default value of the variable. In this case (assuming ${user.name} is used in some task), the value will be prompted, but the field will have ${scope.user.name} as the initial value.

When editing a project setup, be sure to use the Outline view. In the "Unresolved Variables" group in the outline, you'll see the list of variables that will be prompted. It will also show you variables that are used but are undeclared; that's generally an authoring problem because those will be prompted but won't have a nice label and description to explain to the end user the purpose of that variable's value.
