New to Roo and just naively following the "Getting Started with Roo" book tutorial.

Managed to tweak a few commands to operate correctly, but stuck on:

~.model.Customer roo> database reverse engineer --package ~.domain --schema PUBLIC
addon search --requiresDescription "#jdbcdriver,driverclass:org.h2.Driver" found no matches
JDBC driver not available for 'org.h2.Driver'
~.model.Customer roo> addon search --requiresDescription "#jdbcdriver,driverclass:org.h2.Driver"
0 found, sorted by rank; T = trusted developer; R = Roo 1.2 compatible
ID T R DESCRIPTION -------------------------------------------------------------
--------------------------------------------------------------------------------
[HINT] use 'addon info id --searchResultId ..' to see details about a search result
[HINT] use 'addon install id --searchResultId ..' to install a specific search result, or
[HINT] use 'addon install bundle --bundleSymbolicName TAB' to install a specific add-on version
