Troubleshooting code scanning

If you see this error, make sure that GitHub Advanced Security is enabled.

When analyzing your code with code scanning, you may wish to build only the code which you wish to analyze.

You can fine tune your code scanning configuration to minimize analysis time.

If automatic build fails, you can configure code scanning to use specific build steps for compiled languages.

GitHub Advanced Security must be enabled in order to use code scanning on private repositories.

You can check whether or not extraction errors affect the health of the CodeQL database created.

If CodeQL analyzed less code than you expected, you may need to use a custom build command.

If you'd like to increase the level of detail in your logs, try these steps.

When CodeQL fails to find any source code, you need to resolve this problem to unblock code scanning analysis.

CodeQL was unable to locate one of the queries or sets of queries that are specified for analysis.

If you see one of these errors with GitHub Actions, try reviewing the specifications of your self-hosted runners.

If some languages were not analyzed, you can modify your code scanning workflow to add a matrix specifying the languages you want to analyze.

If you see this warning, you should update your workflow to follow current best practice.
