Cannot find "com.vaadin.spring.roo.addon"

Good morning!

I’m a newer user of Vaadin, I was starting follow
this
guide: implementation with Spring Roo, and I’ve encountered an issue following
14.2.3. Installing Vaadin Plugin for Spring Roo
while executing the following command in Spring Roo console:

[i] addon install bundle --bundleSymbolicName com.vaadin.spring.roo.addon [/i] The below warning is what it’s returned once executed the above command:

Could not find specified bundle with symbolic name: com.vaadin.spring.roo.addon I also found
this topic
and tried to follow all related discussions, but nothing happends. (probably they’re too old?)


More informations:

I’m using STS 3.5.0 with Eclipse Kepler

Thanks in advance!
