无法加载JDBC驱动程序类“net.sourceforge.jtds.jdbc.Driver”编译G

这是我的第一篇，所以要温柔！ :)

我已经成立了一个Grails项目（在Grails的太相当新的），并在尝试将其连接到一个SQL 2008数据库，我已经添加了JTDS-1.3.0.jar到lib文件夹，我的构建路径，和然后，我改变了我的DataSource.groovy文件中，内容如下： -

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
        }
    }

麻烦的是，当我尝试编译我得到一个巨大的错误，内容如下，我缺少什么？ 我GOOGLE了约，但不能找到一个显而易见的解决方案...：S

Answer 1:

我有过类似的问题。

我已经改变了JTDS的版本1.2.6和一切工作正常。

顺便说一句 - 你不需要手动添加的罐子。 你只需要以下添加到您的BuildConfig.groovy （相关内容部分）：

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