Source Paths

Source paths can be used to specify source code paths that will trigger a job upon modification. This is done by using a sourcePaths keyword in your job definition as a string or array of strings. This can be useful for running workflows based on subdirectories in a monorepo.

Types of source paths

You can either specify subdirectories and/or specific files as source paths. To denote a subdirectory, leave a trailing slash (/) at the end. The path is relative to the root of the repository.


Given a repository with the file structure depicted below:

├── screwdriver.yaml
├── test/
│   └── ...
├── src/
│   ├── app/
│   │   ├── main.js
│   │   ├── ...
│   │   └── package.json
│   └── other/
│       └── ...

And the screwdriver.yaml:

        image: node:6
        requires: [~pr, ~commit]
        sourcePaths: ["src/app/", "screwdriver.yaml"]
            - echo: echo hi

In this example, the job main will be triggered if there are any changes to files under src/app/ or the screwdriver.yaml file (like on src/app/main.js, src/app/package.json, etc.). The main job will not, however, be triggered on changes to, test/, or src/other/.

Matched source path

Screwdriver will expose the source path that triggered this build in an environment variable SD_SOURCE_PATH. This value will be the first path in sourcePaths which matches any of the modified files and can be used to write scripts which depends on the source path that triggered current build.
