Building from source

Metarank is written in Scala and uses an SBT build system. It can be built on Windows, Linux and MacOS in the following way:

1. Clone the metarank/metarank repo with your favourite git client.

2. Install SBT, using its official installation manual for your OS.

3. From shell, run the sbt assembly command, and metarank build will be built into target/scala-2.13/metarank.jar

$ sbt assembly

Building docker image

Docker image can be built the same way as the JAR bundle, with the following SBT command:

$ sbt docker
