Create a Custom Retrieve Task#

If you will be retrieving changes into a directory repeatedly, consider creating a custom task with the correct options so that you don’t need to specify them on the command line each time.

To do this, add YAML like this to your project’s cumulusci.yml:

tasks:
    retrieve_config_dev:
        description: Retrieves the current changes in the scratch org into unpackaged/config/dev
        class_path: cumulusci.tasks.salesforce.sourcetracking.RetrieveChanges
        options:
            path: unpackaged/config/dev
            namespace_tokenize: $project_config.project__package__namespace

If you’re capturing post-install metadata that will remain unpackaged, it is best to do so starting with a managed installation of your package. This makes it possible to convert references to the package namespace into CumulusCI’s namespace token strings, so that the retrieved metadata can be deployed on top of either managed installations or unmanaged deployments of the package. To set up an org with the latest managed beta release, use the install_beta flow.

Task Recipes#

Run a Shell Command#

run_custom_command:
    description: Greets the user
    class_path: cumulusci.tasks.command.Command
    options:
        command: "echo 'Hello there!'"

Run a sfdx Command#

The dx task lets you run an arbitrary sfdx command. You can perform this with cci on a terminal:

$ cci task run dx -o command 'force:api:limits:display'

Or you can utilize the same class_path as the dx task and make a custom task that can be executed by itself or as a step in a flow.

dx_limits:
    description: Display
    class_path: cumulusci.tasks.sfdx.SFDXBaseTask
    group: dx
    options:
        command: sfdx force:limits:api:display

In this case, we actually utilize SFDXBaseTask, if you would like to run a sfdx command that references an org, utilize SFDXOrgTask instead.

Custom Deploy#

It is often useful to be able to define multiple custom deployment tasks that deployg a specific subset of your projects metadata. This is particularly true when working with unpackaged Metadata.

Here is a custom task that is defined to only deploy only the metadata contained in unmanaged/config/reports.

deploy_reports:
    description: Deploy Reports
    class_path: cumulusci.tasks.salesforce.Deploy
    options:
        path: unmanaged/config/reports

Being able to give this task a new name makes it much more intuitive as to what the task is actually doing. Multiple custom deploy tasks like this allow NPSP to create flows that make it easy to define the order that Metadata is deployed in.

Task to Execute Anonymous Apex#

The following shows an example task named project_default_settings which runs the public static method initializeProjectDefaults() located in file scripts.initialize.cls:

project_default_settings:
    description: Configure the default project settings
    class_path: cumulusci.tasks.apex.anon.AnonymousApexTask
    group: projectName
    options:
        path: scripts/initialize.cls
        apex: initializeProjectDefaults();

Converting from task_options to new-style Options#

If you have custom tasks that you’d like to convert to using the new options API, then you will want to do the following:

  1. Create a nested Options class within the task class.

  2. For each of the options you have defined in the task_options dict you will create a corresponding option property in the Options class.

  3. Delete the task_options dictionary.

  4. Review the _init_options() and _validate_options() methods on the task class – if they exist – to see whether they are still relevant and correct.
