How to Use the Validation Tool for O3DE Submissions
The Open 3D Engine (O3DE) Early Warning System is a tool for style checks and basic static analysis to find errors before building the engine and performing tests. It runs before the pipeline starts a build, attempting to quickly reject invalid changes before spending machine resources to build and test, and minimize human effort on reviewing changes.
Note:The most likely reason you visited this page was to help work past a validation failure. To find the relevant fix, first look at the standard output logs!
Every validation failure will log a message to standard output. Search for
FAILED and find lines of the form:
<path_to_source_file>::ValidatorRuleName FAILED - <failure details> # Example Output VALIDATOR_FAILED: CopyrightHeaderValidator <file>::CopyrightHeaderValidator FAILED - Source file missing copyright headers.
Modify your code to be compliant and resubmit to the Automated Review pipeline. You can also run the validator locally, if you don’t want to wait or want to debug a validator.
If the validator script contains a bug, it is recommended that you open a GitHub Issues ticket .
Files can be checked locally by running scripts located in
Checks all changes within a Git commit, including running Git-specific checks.
python\python.cmd scripts\commit_validation\git_validate_branch.py --source <source branch> --target <target branch>
The validator is able to check arbitrary local files. To do this the validator simulates that every file in the folder (or the one file you specify) is part of your proposed change and changes every line in the file. This causes all the validators to scan as appropriate. The validator does not accept wildcards. Specify a file name, or a folder name and it will operate recursively.
python\python.cmd scripts\commit_validation\validate_file_or_folder.py --path <path to validate>
Connecting this tool into a Continuous Integration system is identical to local use! Simply fail the pipeline when it exits with a non-zero code.
The O3DE Automated Review submission pipeline uses Jenkins to manage this tool.
Validators are created by adding a new class in
Each validator requires the following:
- Inherits from CommitValidator and implements run(self, commit).
- Implements get_validator() and returns the new class.
