Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to This PR changes the scheduled CodeQL scanning workflow and dynamically selects language scans, but the current configuration can omit a language in larger repositories and may not trace Java builds correctly. That could leave parts of the codebase without effective analysis, so the PR is not merge-ready until these bounded CI correctness risks are fixed or explicitly accepted.

GitHub CodeQL workflow configuration paths-ignore compiled languages build mode autobuild Java generated sources
💡 Result:
In GitHub CodeQL, handling generated sources and ignoring specific paths in compiled languages (such as Java) differs significantly depending on the chosen build mode. The standard paths and paths-ignore workflow configuration filters (used for on:pull_request and on:push) only control when a workflow is triggered; they do not instruct the CodeQL extractor to ignore files during the analysis build process [1][2]. Build Modes and Generated Sources For compiled languages, CodeQL analyzes all code built during the workflow execution [2]. Consequently, if you use build-mode: autobuild or build-mode: manual, the resulting CodeQL database will include any generated sources that were compiled by your build system [3][2]. 1. If using build-mode: autobuild: The autobuilder automatically detects and runs your build system (e.g., Maven, Gradle) [4][5]. Because it executes the entire build process, it inherently includes all generated code [2]. To ignore specific paths, you must transition away from autobuild to a manual build [6][2]. 2. If using build-mode: manual: This is the recommended approach for excluding generated sources [2]. You must explicitly define your build steps in the workflow using a run block [7][3]. By crafting your build commands to avoid compiling the generated source directories, you effectively prevent those files from being included in the CodeQL database [6][2]. 3. If using build-mode: none: For Java, you can choose build-mode: none to generate a database directly from the source code without building [3][5]. In this specific mode, you can utilize CodeQL configuration files to apply paths and paths-ignore filters to restrict which files are extracted for analysis [1][2]. Note that this mode is best suited for scenarios where a build is not strictly required for accurate analysis [3]. Summary of Recommendations - For Projects with Complex Builds: Replace autobuild with manual build steps and ensure your build commands explicitly exclude generated source directories [2]. - For Projects where a Build is Unnecessary: Switch to build-mode: none to leverage configuration-based file filtering [1][3]. - Trigger Control vs. Analysis Control: Ensure you distinguish between workflow trigger filters (at the top level of the YAML) and analysis extraction filters (available for none build mode or through custom build commands) [1][2].

Exclude generated Java sources through the build, not paths-ignore. The full matrix uses build-mode: autobuild, and the workflow compiles the Maven project with mvn ... test-compile. CodeQL can include generated sources compiled during built-language analysis. If target/** contains generated Java sources that must be excluded, use a build configuration that omits them.

Consume the complete git ls-files output.
With pipefail, grep -q can close the pipe before git ls-files finishes. For a sufficiently large matching path list, git ls-files can receive SIGPIPE, causing has_files to return false and omit that CodeQL language from the matrix. Replace the early-exiting consumer with one that reads all input.
