How do I use a maven BOM (bill of materials) to manage my dependencies in SBT? - scala

Question

I want to use an external BOM to manage dependency versions for my project in SBT.
For example, the AWS Java SDK publishes a bill-of-materials artifact to their maven repository: https://mvnrepository.com/artifact/com.amazonaws/aws-java-sdk-bom/1.11.86
I can use it to manage versions of dependencies in the AWS SDK. In Maven I can do this by adding the BOM to my <dependencyManagement> section like so:
<dependencyManagement>
<dependencies>
<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk-bom</artifactId>
<version>1.11.86</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
Then when I want to use a module that's covered in the BOM I can omit the version and the BOM will resolve it for me:
<dependencies>
<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk-s3</artifactId>
</dependency>
<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk-sns</artifactId>
</dependency>
</dependencies>
Similarly in Gradle, I can use the BOM to manage dependencies for me using this plugin, like so:
apply plugin: "io.spring.dependency-management"
dependencyManagement {
imports {
mavenBom 'com.amazonaws:aws-java-sdk-bom:1.11.86'
}
}
dependencies {
compile 'com.amazonaws:aws-java-sdk-sns'
compile 'com.amazonaws:aws-java-sdk-s3'
}
Is there a similar plugin for SBT?

Answer 1

I'm looking for the same and have searched in a lot of place.
Most interesting thing I found is it looks like there is Open Ticket on SBT Project:
https://github.com/sbt/sbt/issues/4531
Can't wait that it's resolved !

Have you tried to use Ivy with sbt? It allows you to specify "get latest" by using rev="+"
<ivy-module version="2.0" xmlns:m="http://ant.apache.org/ivy/maven" xmlns:e="http://ant.apache.org/ivy/extras">
<dependencies>
<dependency org="com.amazonaws" name="aws-java-sdk-s3" rev="+" conf="compile->compile(*),master(*);runtime->runtime(*)" />
</dependencies>
</ivy-module>
See http://www.scala-sbt.org/1.0/docs/Library-Dependencies.html

If I understand you correctly, you can add this to your libraryDependencies:
"com.amazonaws" % "aws-java-sdk-bom" % "1.11.800" pomOnly()
You still have to put that version number in a variable and use it with the SDKs you actually want, unless someone knows the right magic to use to use in the revision field. I know you can go latest.release if you want the latest release version.
