播放框架中postgresql 9.2 jar的未解析依赖项

Question

我正在使用postgresql 9.2和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)

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play目录结构的以下位置:

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,运行应用程序时play run,我收到以下错误,并且构建失败:

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

有关如何获得Play的任何提示!识别我的jar文件？

Answer 1

9.2版本的Postgresql驱动程序还没有打到Maven中央仓库,所以你必须使用9.1版本:

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

或者您可以通过删除myApp/lib文件夹中的JAR 并删除文件中的任何依赖项来使用9.2版本project/Build.scala(该lib文件夹由sbt自动添加).

Answer 2

我在存储库中找到了这个 :

"org.postgresql" % "postgresql" % "9.2-1003-jdbc4"
