SBT alternative for maven's dependencyManagement

Question

In our multi-project codebase, we are using Maven as build framework.
However, we have a Play framework based module, for which we have to use SBT build.

In Maven projects, we have dependencyManagement configured through another project called "version" and included in pom.xml, as follows.

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>com.xxxx.release</groupId>
            <artifactId>xxxx-version</artifactId>
            <version>${project.version}</version>
            <scope>import</scope>
            <type>pom</type>
        </dependency>
    </dependencies>
</dependencyManagement>

This makes sure to pull correct version of dependency jars for the specific build.

Is there a way to achieve same with SBT?

Answer 1

You can create an in-house sbt plugin that defines something like the follows:

package com.example

import sbt._

object Dependencies {
  // versions
  lazy val akkaVersion = "2.5.22"

  // libraries
  val akkaActor = "com.typesafe.akka" %% "akka-actor" % akkaVersion
  val akkaCluster = "com.typesafe.akka" %% "akka-cluster" % akkaVersion
}

After adding the plugin to your Play app, you can write inside build.sbt as follows:

import com.example.Dependencies._

and akkaActor will be available as a name.
