Cannot load JDBC driver class 'net.sourceforge.jtds.jdbc.Driver' when compiling Grails project

This is my first post so be gentle! :)

I've set up a grails project (fairly new at grails too) and am attempting to connect it to a SQL 2008 database, I've added the jtds-1.3.0.jar to the lib folder and to my build path, and then I've altered my DataSource.groovy file to read as follows: -

dataSource {
    pooled = true
    driverClassName = "net.sourceforge.jtds.jdbc.Driver"
    dialect = "org.hibernate.dialect.SQLServerDialect"
    }

hibernate {
    cache.use_second_level_cache = true
    cache.use_query_cache = false
    cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory'
}


// environment specific settings
    development {
        dataSource {
            dbCreate = "update"
        url= "jdbc:jtds:sqlserver://TestServer:1433;databaseName=TestTable"
            username = "test"
            password = "test"
        // logSql=true
        }
    }

Trouble is when I try to compile I get a massive error which reads as follows, what am I missing? I've googled about but can't find an obvious solution... :S

I have had similar problems in the past.

I've changed the version of JTDS to 1.2.6 and all works fine.

By the way - you don't need to add the jar manually. You just have to add the following to your BuildConfig.groovy (in the dependencies section):

runtime 'net.sourceforge.jtds:jtds:1.2.6'
