将外部项目依赖项添加到我的Play应用程序中

Question

At the moment I am using a pretty basic build.sbt file which was created by activator and gives me a Play application

My goal is to add an external Project dependency to my Play application.

My build.sbt file looks along the lines of

libraryDependencies ++= Seq(
...
)

lazy val root = (project in file(".")).enablePlugins(PlayScala)
pipelineStages := Seq(rjs, digest, gzip)

Is the only way to add a dependency on an external project to change to using a build.scala file? If so, is it possible for the Build.scala file to reference the current build.sbt file?

The external project also has its own Build.scala file, so is it possible to reference from the "master" Build file to the external projects?

Thanks

You have two options:

1. Publish to Ivy and resolve (see: http://www.scala-sbt.org/0.13/docs/Publishing.html#Publishing+Locally )
2. Directly reference the other project, eg in your build.sbt.

Here's what option #2 looks like:

lazy val other = file("/path/to/other").getAbsoluteFile.toURI

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