Dependencies Locked

✓ Guardrail Scala Project Guardrails Beta Devex Build And Ci

scala.dependencies-locked

Ensures dependencies are locked for reproducible builds — either via build.sbt.lock (sbt-lock plugin) or an equivalent Mill/Maven lock mechanism. Informational by default — most Scala projects do not lock dependencies, but doing so produces reproducible CI builds.

How This Guardrail Works

This guardrail is part of the Scala Project Guardrails policy. It evaluates data collected by integrations and produces a pass/fail check with actionable feedback.

When enabled, this check runs automatically on every PR and in AI coding workflows, providing real-time enforcement of your engineering standards.

Configuration Options

These inputs can be configured in your lunar-config.yml to customize how the parent policy (and this guardrail) behaves.

Input	Required	Default	Description
`min_scala_version`	Optional	`2.12`	Minimum required Scala compiler version (e.g., "2.12", "2.13", "3.3.1"). Compared with semantic-version semantics — "2.13" matches 2.13.x and 3.x, but rejects 2.11.x.
`min_sbt_version`	Optional	`1.9`	Minimum required sbt version (e.g., "1.9", "1.10.0"). Compared with semantic-version semantics. Skipped when the project does not use sbt.
