How to get project information from build in Scala project code?

问题

I have a Scala/sbt project. The project's version is in the sbt Build.scala file.

I need to have an "about" feature that gives the product version to the user. How do I read from the SBT build file from within the Scala source?

For example, given project/Build.scala:

import sbt._

object ApplicationBuild extends Build {
  val appName         = "foo-product"
  val appVersion      = "1.1.0"
}

What I'd really like is to just be able to do ApplicationBuild.appVersion, but that doesn't seem possible.

How can this be achieved?

回答1:

You can use sbt-buildinfo plugin.

The plugin generates a BuildInfo object, which contains information you need.
