Question

A DevOps engineer maintains a monorepo containing services written in Go, JavaScript, and Java. They want to enable CodeQL code scanning via GitHub Actions so that each language is analyzed independently and failures in one language's analysis do not block the others. Which approach best achieves this within a single workflow file?

Accepted Answer

Define a matrix strategy with fail-fast: false and a 'language' variable listing go, javascript, and java, so a separate job runs the init/analyze steps per language

Answer

Create one job that passes all three languages as a comma-separated string to the 'languages' input of the github/codeql-action/init step

Answer

Set the workflow to run on a nightly schedule only, since CodeQL cannot analyze more than one compiled language per push event

Answer

Add three separate workflow files, one per language, because a single workflow cannot invoke the CodeQL action more than once
