If an automatic build of code for a compiled language within your project fails, try removing the autobuild step from your {% data variables.product.prodname_code_scanning %} workflow and adding specific build steps. For more information about replacing the autobuild step, see "AUTOTITLE."

If your workflow doesn't explicitly specify the languages to analyze, {% data variables.product.prodname_codeql %} implicitly detects the supported languages in your code base. In this configuration, out of the compiled languages {% data variables.code-scanning.compiled_languages %}, {% data variables.product.prodname_codeql %} only analyzes the language with the most source files. Edit the workflow and add a matrix specifying the languages you want to analyze. The default {% data variables.product.prodname_codeql %} analysis workflow uses such a matrix.

The following extracts from a workflow show how you can use a matrix within the job strategy to specify languages, and then reference each language within the "Initialize {% data variables.product.prodname_codeql %}" step:

jobs:
  analyze:
    permissions:
      security-events: write
      actions: read
    ...
    strategy:
      fail-fast: false
      matrix:
        language: ['csharp', 'cpp', 'javascript']

    steps:
    ...
      - name: Initialize {% data variables.product.prodname_codeql %}
        uses: {% data reusables.actions.action-codeql-action-init %}
        with:
          languages: {% raw %}${{ matrix.language }}{% endraw %}
