无法加载JDBC驱动程序类'；net.sourceforge.jtds.jdbc.Driver'；编译Grails项目时

这是我的第一篇帖子，所以请温柔一点！：）

我已经建立了一个grails项目（在grails上也相当新），并试图将其连接到SQL 2008数据库，我已经将jtds-1.3.0.jar添加到lib文件夹和构建路径中，然后我修改了DataSource.groovy文件，如下所示：-

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
        }
    }

问题是，当我试图编译时，我得到了一个巨大的错误，如下所示，我遗漏了什么？我在谷歌上搜索过，但找不到明显的解决方案…：

我过去也有过类似的问题

我已将JTDS的版本更改为1.2.6，所有工作正常

顺便说一下，您不需要手动添加jar。您只需将以下内容添加到

BuildConfig.groovy

（在依赖项部分中）：

+1需要注意的是，jTDS 1.3.0需要Java 7，如果您使用Java 6，它将不会加载。+1现在编译良好，使用运行时注释也很有用！谢谢！：）jTDS v1.3.1一直希望加载一个message_en_US.properties文件，该文件不包含在jar文件中。只有message.properties是可用的。我一回到1.2.6，这个问题就消失了。但是我仍然无法在tomcat上部署war文件。同样的错误

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