Warn when workflow analyzes the same language twice by henrymercer · Pull Request #1901 · github/codeql-action (original) (raw)
With the introduction of new aliases for C/C++, Java/Kotlin, and JavaScript/TypeScript, we want to avoid customers analyzing the same language more than once. The most common case of this will likely be customers who have started with a starter workflow and have added a duplicate language to the language matrix parameter.
This PR introduces workflow validation for this common case, so that customers who are analyzing the same language twice will get an Actions warning when they execute that workflow.
