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

Question

这是我的第一篇帖子,所以要温柔!:)

我已经设置了一个grails项目(相当粗糙的grails项目)并尝试将其连接到SQL 2008数据库,我已将jtds-1.3.0.jar添加到lib文件夹和我的构建路径中,然后我将我的DataSource.groovy文件修改为如下: -

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,当我尝试编译时,我得到一个大的错误,如下所示,我错过了什么？我用google搜索但找不到明显的解决方案......:S

我过去也遇到过类似的问题.

我已经将JTDS的版本更改为1.2.6并且一切正常.

顺便说一下 - 你不需要手动添加jar.您只需将以下内容添加到您的BuildConfig.groovy(在依赖项部分中):

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