How to run multiple sbt projects in parallel?

I have a multi-project sbt build (each project is micro service). For development convenience, I want to run all of them at the same time. Is it possible with sbt?

lazy val root = (project in file("."))
  .aggregate(
    serviceA,
    serviceB
  )

lazy val serviceA = (project in file("service-a"))
 ...

 lazy val serviceB = (project in file("service-b"))
 ...

I can run them individually with serviceA/run or serviceB/run

But I need to run serviceA and serviceB with single sbt command (they will be running on different ports)

You could try to use Ammonite

We us Ammonite scripts (e.g. runner.sc) to run sbt. I never used Future as we run one thing after the other.

Or use a simple bash file:

Your requirement is more or less running sbt in the background. Here is an according question: how-to-run-sbt-as-daemon

Taking this to your question, this could look like:

#!/usr/bin/env bash

sbt -Djline.terminal=jline.UnsupportedTerminal serviceA/run &
sbt -Djline.terminal=jline.UnsupportedTerminal serviceB/run &

I couldn't test this, let me know if it works.
