Q:

Why Spring Roo is showing only a single addon?

Running addon search --refresh returns only a single result:
roo> addon search --refresh
Successfully downloaded Roo add-on Data
1 found, sorted by rank; T = trusted developer; R = Roo 1.2 compatible
ID T R DESCRIPTION -------------------------------------------------------------

       Scaffolding; #mvc,#localization,locale:hi

I am using spring-roo version 1.2.2

A:

There have been a handful of problems with the addon repository in recent months - see here, for example. The (somewhat annoying) workaround is that if you can locate the URL for an addon you're interested in, you can still load it via the 'osgi obr url add' and 'osgi obr deploy' commands.  You can see an example here.
