SBT task configuration for VS Code

1 minute read

Here is my tasks.json for using Visual Studio Code with sbt projects:

Why bother?

There are two main IDE’s used with scala, Eclipse and IntelliJ. But for my taste both of them are too heavy and resource hungry.

I am used to Visual Studio Code because it is excellent for Javascript and Typescript, so my node.js and Angular projects work very well. I also do a fair amount of work on small cloud servers and devices like Raspberry Pi, so I want to build each project from command line by pulling the project from github, executing a build script and running the project.

This means the build scripts must be able to run without an IDE. So I settled on sbt for my Scala projects which can even be run on a Raspberry Pi with some memory tweaks.

This gives two options:

  • running the build commands from command line completely outside the IDE
  • or integrating the build commands.

I want to have both options at my fingertips, so I wanted to configure the following sbt commands in Visual Studio Code:

  • sbt run
  • sbt test
  • optional: sbt compile and/or sbt package

Visual Code has a configuration for external tasks in the file .vscode/tasks.json in your project, and the file is described on the VS Code Website

You can configure several tasks for one main command. The task with the name “build” also has a keyboard shortcut out of the box.

THe configuration shown above is the one which works for me as a starting point. Maybe I will add or change something later, but for now it does the job.

Conclusion

I hope this may be of help, at least this note will serve as a reminder to myself how to configure sbt tasks in Visual Studio Code.
