Common source options

Unless the part plugin overrides this behaviour, a part can use these source keys in its definition. They tell snapcraft where to pull source code for that part, and how to unpack it if necessary.

  • source: url-or-path

    A URL or path to some source tree to build. It can be local (./src/foo) or remote (, and can refer to a directory tree or a tarball or a revision control repository (git:...).

  • source-type: git, bzr, hg, svn, tar, or zip

    In some cases the source string is not enough to identify the version control system or compression algorithm. The source-type key can tell snapcraft exactly how to treat that content.

  • source-depth: <integer>

    By default clones or branches with full history, specifying a depth will truncate the history to the specified number of commits.

  • source-branch: <branch-name>

    Snapcraft will checkout a specific branch from the source tree. This only works on multi-branch repositories from git and hg (mercurial).

  • source-commit: <commit>

    Snapcraft will checkout the specific commit from the source tree revision control system.

  • source-tag: <tag>

    Snapcraft will checkout the specific tag from the source tree revision control system.

  • source-subdir: path

    Snapcraft will checkout the repository or unpack the archive referred to by the source keyword into parts/<part-name>/src/ but it will only copy the specified subdirectory into parts/<part-name>/build/.

  • source-checksum: <algorithm>/<checksum>

    Snapcraft will use the checksum specified to verify the integrity of the source. The source-type of the source needs to be a file (tar, zip, deb or rpm) and the algorithm either md5, sha1, sha224, sha256, sha384, sha512, sha3_256, sha3_384 or sha3_512. Prepend the checksum with its type, e.g. sha256/<checksum>.

Note that plugins might well define their own semantics for the source keywords, because they handle specific build systems, and many languages have their own built-in packaging systems (think CPAN, PyPI, NPM). In those cases you want to refer to the help text for the specific plugin.
