Slick（Scalaquery）-插入时给出类型错误

我在play framework应用程序中使用了Slick（Scalaquery）。根据-我可以为要插入的列定义投影。（我定义这个投影是因为我的索引是一个自动递增的列。）但是，当我在插入中使用这个投影时，我得到一个类型错误，它说：

[NoSuchMethodError: scala.Predef$.augmentString(Ljava/lang/String;)Ljava/lang/String;].

我的模型定义如下：

package models

import play.api.db._
import play.api.Play.current

import scala.slick.driver.PostgresDriver.simple._
import scala.slick.ql.{MappedTypeMapper}
import scala.slick.session.{Session, Database}

case class Book(name: String, filename: String)

object Book extends Table[(Long, String, String)]("book") {

  lazy val database = Database.forDataSource(DB.getDataSource())
  def id = column[Long]("id", O PrimaryKey, O AutoInc)
  def name = column[String]("name", O NotNull)
  def filename = column[String]("filename", O NotNull)
  def * = id ~ name ~ filename
  def withoutId = name ~ filename

  def findAll() : Seq[Book] = database.withSession { implicit db:Session =>
    (for(t <- this) yield t.name ~ t.filename).list.map(attrs => Book(attrs._1, attrs._2))
  }

  def create(book: Book): Unit = database.withSession { implicit db:Session =>
    this.withoutId insert(book.name, book.filename)
  }

}

有人能帮我指出我的插件出了什么问题吗？

Scala 2.9不支持SLICK（在Play中使用）。所有“适当”的光滑构建（在scala.SLICK名称空间中，并带有新的前端）都需要scala 2.10.0-M4或-M5。Scala 2.9上支持的最新版本是ScalaQuery 0.10.0-M1

根据您在代码段中使用的功能判断，ScalaQuery 0.10.0-M1甚至0.9的所有功能都应该以相同的方式工作（除了不同的导入）。

jar中的版本强烈建议您面临二进制不兼容：Slick（Slick_2.10.0-M4-0.10.0-M2.jar）是为Scala 2.10.0-M4编译的，而不是为Scala 2.10.0-M4编译的（play_2.9.1-2.0.2.jar）和其他都是为2.9.1编译的
