Note: The CodeQL runner is currently in beta and subject to change.
Before the CodeQL runner can build and analyze code, it needs access to the CodeQL bundle, which contains the CodeQL CLI and the CodeQL libraries.
When you use the CodeQL runner for the first time on your machine, the
init command downloads the CodeQL bundle to your machine. This download can take a few minutes.
The CodeQL bundle is cached between runs, so if you use the CodeQL runner again on the same machine, it won't download the CodeQL bundle again.
To avoid this automatic download, you can manually download the CodeQL bundle to your machine and specify the path using the
--codeql-path flag of the
analyze command for the CodeQL runner fails with an error
No source code was seen during the build, this indicates that CodeQL was unable to monitor your code. Several reasons can explain such a failure.
Automatic language detection identified a supported language, but there is no analyzable code of that language in the repository. A typical example is when our language detection service finds a file associated with a particular programming language like a
.gypfile, but no corresponding executable code is present in the repository. To solve the problem, you can manually define the languages you want to analyze by using the
--languagesflag of the
initcommand. For more information, see "Configuring code scanning in your CI system."
You're analyzing a compiled language without using the
autobuildcommand and you run the build steps yourself after the
initstep. For the build to work, you must set up the environment such that the CodeQL runner can monitor the code. The
initcommand generates instructions for how to export the required environment variables, so you can copy and run the script after you've run the
- On macOS and Linux:
$ . codeql-runner/codeql-env.sh
- On Windows, using the Command shell (
cmd) or a batch file (
> call codeql-runner\codeql-env.bat
- On Windows, using PowerShell:
> cat codeql-runner\codeql-env.sh | Invoke-Expression
The environment variables are also stored in the file
codeql-runner/codeql-env.json. This file contains a single JSON object which maps environment variable keys to values. If you can't run the script generated by the
initcommand, then you can use the data in JSON format instead.
Note: If you used the
--temp-dirflag of the
initcommand to specify a custom directory for temporary files, the path to the
codeql-envfiles might be different.
- On macOS and Linux:
The code is built in a container or on a separate machine. If you use a containerized build or if you outsource the build to another machine, make sure to run the CodeQL runner in the container or on the machine where your build task takes place. For more information, see "Running CodeQL code scanning in a container."
