download

This field specifies a git repository to download the module’s source files from.

Modules with download automatically have is_build_dep set to true, and their srcdir points to the download directory.

The context must define GIT_DOWNLOAD and (if using patches) GIT_PATCH rules.

fields

• git: Required. A map with url and one of commit, branch, or tag.
• patches: Optional. A list of patch files to apply after download.
• dldir: Optional. A string overriding the download directory. Defaults to build/dl/<relpath>/<module_name>.
