> For the complete documentation index, see [llms.txt](https://cover-docs.diffblue.com/llms.txt). Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://cover-docs.diffblue.com/features/cover-cli/project-configuration/configuring-cover-to-work-with-your-projects-build-system/default-configuration.md). # Default configuration By default, Cover uses its own internal configuration to interact with your project's build system. Currently, Cover supports Maven and Gradle automatically, and provides a sample configuration for Ant that you will need to customize to suit your project. You can retrieve this default configuration and use it as a starting point for defining your own `DiffblueBuild.yaml` file that then overrides the default behaviour. ## Default Maven configuration For the latest version of this configuration (including comments describing the content, which are omitted here for brevity), run `dcover build-default-config --maven`. {% code title="DiffblueBuild.yaml" fullWidth="true" %} ```yaml meta: version: 3.2 toolName: maven cmd: windows: -
