Play框架中对PostgreSQL 9.2 jar的未解决依赖性 [英] unresolved dependency for postgresql 9.2 jar in play framework

问题描述

我正在将PostgreSQL 9.2和Play框架2.1一起使用

I am using postgresql 9.2 with play framework 2.1

我在这里下载了驱动程序: http://jdbc.postgresql.org/download.html (JDBC4 Postgresql驱动程序，版本9.2-1002)

I downloaded the driver here: http://jdbc.postgresql.org/download.html (JDBC4 Postgresql Driver, Version 9.2-1002)

我的project/Build.scala文件如下:

import sbt._
import Keys._
import play.Project._

object ApplicationBuild extends Build {

  val appName = "myApp"
  val appVersion = "0.1"

  val appDependencies = Seq(
    "postgresql" % "postgresql" % "9.2-1002.jdbc4")

  val main = play.Project(appName, appVersion, appDependencies)
}

我已将jdbc驱动程序放在播放目录结构中的以下位置:

I have placed the jdbc driver in the following locations in the play directory structure:

myApp/lib/postgresql-9.2-1002.jdbc4.jar
myApp/lib/9.2-1002.jdbc4.jar
myApp/lib/postgresql/postgresql/9.2-1002.jdbc4.jar

但是，使用play run运行应用程序时，出现以下错误，构建失败:

However, running the app with play run, I get the following error and the build fails:

[warn]  module not found: postgresql#postgresql;9.2-1002.jdbc4

有关如何获得Play的任何提示！识别我的jar文件?

推荐答案

Postgresql驱动程序9.2版本

The 9.2 version of Postgresql driver has not yet hit the Maven central repo, so you'll have to use the 9.1 version :

"postgresql" % "postgresql" % "9.1-901-1.jdbc4"

或者您可以通过将放到myApp/lib文件夹中并从project/Build.scala文件中删除任何依赖项来使用9.2版本(lib文件夹由sbt自动添加).

Or you can use the 9.2 version by dropping the JAR in your myApp/lib folder and remove any dependency from your project/Build.scala file (the lib folder is automatically added by sbt).
