GitHub Actions / SARIF

⚠️ This is still an alpha feature.

Λrrow Analysis generates a so-called SARIF report as part of its output. SARIF is a standard interchange format for static analysis, which can be later consumed by many different tools. When using the Gradle plug-in, the file can be found in the build/generated folder.

One very useful integration is with GitHub’s Code Scanning. In that case the results of the analysis appear as part of the workflow output, annotating the source code itself. You can see an example for an “unsatisfiable pre-condition” error.

ℹ️ Unfortunately, you need to pay for Code Scanning in private repos. For public ones you can enable it in the Security & analysis tab in the repo settings.

The following snippet shows how to configure your GitHub Action workflow to make it aware of Code Scanning. We assume that you’ve [configured your Gradle project to run Λrrow Analysis]((/docs/analysis/) as part of the build task. The next step is to take all the SARIF files and put them in a single folder, what we call “bundle analysis report” here. Finally you use the upload-sarif action, passing the name of the folder where you’ve gathered the SARIF files. We use if: always() because otherwise the results would only be uploaded on a succesful run, which is the least interesting scenario for an analysis tool.

      - name: Bundle analysis report

        run: mkdir sarif && find . -name '*.sarif' | xargs -I{} cp "{}" ./sarif/

      - name: Upload analysis report
        if: always()
        uses: github/codeql-action/upload-sarif@v1
          sarif_file: sarif # path relative to root
