试图在MS sql server中配置grails app

Question

在lib中我正在添加 jar（jtds：1.2.6.jar）文件。
但它收到的错误如下：

  

无法加载您的jar文件

sql.groovy：

package com
class Sql {

    String project

    String title

    static constraints = {

        project blank:false

        title blank:false
    }
}

Datasource.groovy

dataSource {

 pooled = true

     driverClassName = "net.sourceforge.jtds.jdbc.driver"
    username = "sa"
    password = ""
    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

environments {

    development {

        dataSource {

            dbCreate = "update" // one of 'create', 'create-drop', 'update', 'validate', ''
      url = "jdbc:jtds:sqlserver://ASIA-IN-GJVX022:1433;databaseName=Haritha;instance=SQLEXPRESS"
        }

    }
    test {

        dataSource {

            dbCreate = "update"

            url = "jdbc:h2:mem:testDb;MVCC=TRUE;LOCK_TIMEOUT=10000"
        }
    }
    production {

        dataSource {

            dbCreate = "update"
            url = "jdbc:h2:prodDb;MVCC=TRUE;LOCK_TIMEOUT=10000"
            pooled = true
            properties {
               maxActive = -1
               minEvictableIdleTimeMillis=1800000
               timeBetweenEvictionRunsMillis=1800000
