我在 Spring Roo 中使用 postgres，当我在安装时尝试使用 DBRE
database introspect --schema no-schema-required
回应是
addon search --requiresDescription "#jdbcdriver,driverclass:org.postgresql.Driver" found no matches
JDBC driver not available for 'org.postgresql.Driver'
甚至手动搜索
addon search --requiresDescription "#jdbcdriver,driverclass:org.postgresql.Driver"
结果是
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
我使用的是 STS 3.1，我有互联网连接。
我以前试过这个，它奏效了。会发生什么？
