> I have a simple piece of groovy for accessing a (oracle) DB.
> The code works fine once I include the jdbc jar in my $GROOVY_HOME/lib folder.
> However I would like to use grape to dynamically manage dependencies so I changed the code to below.
> {code}
> import groovy.grape.Grape
> Grape.grab(group:'oracle', module:'ojdbc14', version:'10.1.0.4.0' )
> import groovy.sql.Sql
> import java.sql.Time
> def db = Sql.newInstance("jdbc:oracle:thin:@flagtest.intmet.ie:1525:BEAM", "user", "password", 
> 		"oracle.jdbc.driver.OracleDriver")
> {code}
> This results in 
> {code}
> Caught: java.sql.SQLException: No suitable driver
>         at t2.run(t2.groovy:8)
> {code}
> If I add the following import after the Grape.grab 
> {code}
> import oracle.jdbc.driver.OracleDriver
> {code}
> I get the following
> {code}
> org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed,
> C:\dev\t2.groovy: 4: unable to resolve class oracle.jdbc.driver.OracleDriver
>  @ line 4, column 1.
>    import oracle.jdbc.driver.OracleDriver;
