使用 sbt 添加 slick 依赖项时出错

Question

我是 scala 世界的新手（来自 android 世界），我用 play-framework 创建了 scala 项目，现在一切正常我需要添加数据库，为此我决定选择 slick，但是当我尝试添加这样的依赖项时

libraryDependencies ++= Seq(
  "com.typesafe.slick" %% "slick" % "3.1.0",
  "org.slf4j" % "slf4j-nop" % "1.6.4"
)

我收到了这个错误日志

这是我的坑 sbt 构建脚本

name := """play-scala-starter-example"""

version := "1.0-SNAPSHOT"

lazy val root = (project in file(".")).enablePlugins(PlayScala)

resolvers += Resolver.sonatypeRepo("snapshots")

scalaVersion := "2.12.2"
libraryDependencies ++= Seq(
  "com.typesafe.slick" %% "slick" % "3.1.0",
  "org.slf4j" % "slf4j-nop" % "1.6.4"
)
libraryDependencies ++= Seq(
  jdbc,
  "com.typesafe.play" %% "anorm" % "2.5.3"
)

libraryDependencies += guice
libraryDependencies += "org.scalatestplus.play" %% "scalatestplus-play" % "3.0.0" % Test
libraryDependencies += "com.h2database" % "h2" % "1.4.194"
libraryDependencies += jdbc
libraryDependencies += "mysql" % "mysql-connector-java" % "5.1.41"

Answer 1

根据我在 maven 上的发现，似乎只有少数版本的 slick 是针对 scala 2.12 编译的：

• 3.2.1
• 3.2.0
• 2.1.0

见：http://search.maven.org/#search%7Cgav%7C1%7Cg%3A%22com.typesafe.slick%22%20AND%20a%3A%22slick_2.12%22

使用更新版本的 slick 或其他 scala 版本 (2.11.x)。

将以下行添加到您的build.sbt

 resolvers += "typesafe" at "http://repo.typesafe.com/typesafe/releases/"
