如何将JDBC驱动程序作为系统依赖项放置在SBT项目中以开发模式进行Scala / Play项目

Question

I have a bunch of dependencies, such as JDBC Drivers, from vendors like Oracle, and Microsoft, which are not on a Public Artifact Repository.

Everytime I want those dependencies to be available while running my Play Application in Dev Mode , I have to put those jars in lib folder(within the play project)

Those drivers are supposed to vary from Customer to Customer, and in some phases of the project we need a Oracle one, some other phase, 2 drivers.

Another point is that, we have multiple Play Applications that we use those drivers, and have to manually place them within the lib folder

How can I avoid this??

I need those jars in the classpath for when I am saying from the command line:

sbt run "play-project" -Dhttp.port=9001

Maybe there is some play parameter that I can also pass an additional classpath.

I am using Play 2.4 and Scala 2.11.7

I think you have two solutions:

1. Add your specifics jar files in a common folder and reference that one from your build file. You should add some environment properties or some configurable way to allow other people from your team to configure the jars location.

2. Create a private maven or ivy repository that contains the specific jars. It could be as simple as a http server with the files and the correct directory structure. This allows you to internally distribute the jar file without having people to configure specific folders on their machines.

For the first solution, from SBT documentation , you should just add those jars in your unmanaged classpath, with in your build.sbt file a line like:

unmanagedJars in Compile := (file("/my_common_path") ** "*.jar").classpath

For the second solution, just have a look at sbt's resolver documentation
