知道如何为 scala 2.10.1 构建SORM我正在尝试生成一个可以在我的 eclipse 项目中使用的 jar 文件。
这是我的代码
import sorm._
case class Coffee(name: String, supplier: Supplier, price: Double, sales: Int, total: Int)
case class Supplier(name: String, street: String, city: String, state: String, zip: String)
object Db extends Instance(
entities = Set(Entity[Coffee](),Entity[Supplier])),url="jdbc:mysql://localhost:3306/db123")
object sormtest {
import Db._
def main(args: Array[String]): Unit = {
val supplier1 = Supplier("Acme, Inc.", "99 Market Street", "Groundsville", "CA", "95199")
val supplier2 = Supplier("Superior Coffee", "1 Party Place", "Mendocino", "CA", "95460")
val supplier3 = Supplier("The High Ground", "100 Coffee Lane", "Meadows", "CA", "93966")
Db.save(supplier2) }}`
我收到以下错误:

我已经从这里下载了 jar 文件http://mvnrepository.com/artifact/org.sorm-framework/sorm/0.3.8
编辑:Maven 存储库列出了许多要包含的 jar 文件。一旦我添加了它们就解决了我的问题。
