unresolved dependency for postgresql 9.2 jar in pl

问题:

I am using postgresql 9.2 with play framework 2.1

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

My project/Build.scala file is as follows:

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)
}

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

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

Any tips on how to get the Play! to recognize my jar file?

回答1:

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"

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).

I have found this in the Repository:

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

When I change 9.2 version to 9.1 version, it works perfectly. Thanks for your answer nico_ekito

My buid.scala

  val appDependencies = Seq(
  "postgresql" % "postgresql" % "9.1-901-1.jdbc4",
  jdbc,
  javaCore,
  javaEbean
  )

My application.conf

db.default.driver=org.postgresql.Driver
db.default.url="jdbc:postgresql://localhost:5432/DBName"
db.default.user=postgres
db.default.password=123456

I solved the problem using the information at the following link:

In file application.conf:

 db.default.driver=org.postgresql.Driver
 db.default.url="jdbc:postgresql://localhost:5432/dataBaseName"
 db.default.user=user
 db.default.password="password"

create the pasta /lib in your main project and should add the .jar do postgres.

Download here, and after reload the project.
