Roo install i18n

when trying to create a i18n addon :

roo > addon create i18n --topLevelPackage com.gilles.photos.addon --locale ic --messageBundle i18n/messages_ic.properties

I get the message :

Command 'addon create i18n --topLevelPackage com.gilles.photos.addon --locale ic --messageBundle i18n/messages_ic.properties' was found but is not currently available (type 'help开发者_JS百科' then ENTER to learn about this command)

I try to follow the recommandations of this post : http://forum.springsource.org/showthread.php?101843-addon-create-i18n-does-not-work

The advices of the guy are opaque to me. What does he mean by :

The addon create commands need to be run in an empty directory

There are no clear answer available on the web.

What are you exactly trying to do? To install support for a given language; use

web mvc install language --code it

Where it is the code of the language. "Roo currently support six languages, and you can write an add-on language for others of your choice" - as of February, 2011. The command you were trying is the one that's supposed to create an addon for a language which is not yet supported. (I don't think that's your intention)

EDIT after question clarification:

See roo documentation, section A.5.2. What you have to do is

• acquire an existing messages_xx.properties (checkout roo source and find them here: ..\addon-web-mvc-jsp\src\main\resources\org\springframework\roo\addon\web\mvc\jsp\i18n\languages)
• from one of these files, create the _ic.properties.
• crate a subdirectory called i18n in an empty directory, place messages_ic.properties there
• issue the command you tried: addon create i18n --topLevelPackage foo.bar --locale ic --messageBundle i18n/messages_ic.properties
