Contributing

Workflow

Clone the project and create a branch off the main branch. Commit your changes, push them to a fork of this repository, and create a pull request.

Build the Project

Use sbt to build the project:

sbt

And then:

compile

And, to run all the tests, on all the supported Scala versions:

+test

To check that you didn’t break the intended binary or source compatibility:

versionPolicyCheck

To build and preview the documentation:

previewSite

To format the source code:

scalafmt

Publish a Release

We use sbt-ci-release. To publish a release, push a tag (e.g. v.2.3.4) on the main branch and let the CI publish the release. The CI job checks that the version number in the tag is consistent with the declared compatibility intention, publishes the artifacts to Maven Central, and publishes the website to https://endpoints4s.github.io/scalaj.

Then, reset the compatibility intention to BinaryAndSourceCompatible (see below).

Write the release notes on the releases page. The release notes must document all the deprecations and breaking changes, all the bug fixes, and all the new features.

Compatibility Policy

This project follows Semantic Versioning.

It uses sbt-version-policy to manage the compatibility checks and version checks.

After a release, reset versionPolicyIntention to BinaryAndSourceCompatible:

// in build.sbt
versionPolicyIntention := Compatibility.BinaryAndSourceCompatible

If you submitted a PR and the CI tells you that you have to relax the compatibility intention, update versionPolicyIntention accordingly:

// in build.sbt
versionPolicyIntention := Compatibility.BinaryCompatible
// or
versionPolicyIntention := Compatibility.None
