Default setup overrides existing CodeQL setups by disabling any existing CodeQL workflows, and blocking any CodeQL analysis API uploads. This behavior stops you using GitHub Actions minutes to run workflows for CodeQL advanced setup when only the results from default setup will be used. For more information about switching between advanced and default setups, see Results are different than expected.
Optionally, if you are certain you no longer need the pre-existing workflow file, you can delete the file from your repository. For more information, see 删除仓库中的文件.
在某些情况下，存储库可能会使用多个code scanning配置。 这些配置可能会生成重复的警报。 此外，不再运行的过时配置将显示过时的警报状态，过时的警报将无限期保持打开状态。 为了避免警报过时，应从分支中删除移除过时的code scanning配置。 有关多个配置和删除过时配置的详细信息，请参阅“关于代码扫描警报”和“解决代码扫描警报”。
