Cannot retrieve WorkflowAlert, WorkflowFieldUpdate, WorkflowRule from package.xml through sfdx cmd

Question

I want to retrieve all my WorkflowAlert, WorkflowFieldUpdate, WorkflowRule from my sandbox and deploy them to another one. Here is my package.xml file :

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Package xmlns="http://soap.sforce.com/2006/04/metadata">
    <types>
        <members>*</members>
        <name>ApexClass</name>
    </types>
    <types>
        <members>*</members>
        <name>ApexComponent</name>
    </types>
        ...
    <types>
        <members>*</members>
        <name>EmailTemplate</name>
    </types>
    <types>
        <members>*</members>
        <name>WorkflowAlert</name>
    </types>
    <types>
        <members>*</members>
        <name>WorkflowFieldUpdate</name>
    </types>
    <types>
        <members>*</members>
        <name>WorkflowRule</name>
    </types>
    <version>48.0</version>
</Package>

I then used this command line to retrieve those metadata :

sfdx force:source:retrieve --manifest /path/to/package.xml

But it return everything except WorkflowAlert, WorkflowFieldUpdate, WorkflowRule.

Please how to retrieve WorkflowAlert, WorkflowFieldUpdate, WorkflowRule ?

Answer 1

Those elements are still "bundled" in this release (7.50) of DX (and all prior versions). To extract them, use the Workflow object:

<types>
    <members>*</members>
    <name>Workflow</name>
</types>

You'll have files in the folder workflows, named after the object for which the metadata pertains to (e.g. Account.workflow-meta.xml or Custom_Object__c.workflow-meta.xml) which will contain XML like the following:

<Workflow xmlns="http://soap.sforce.com/2006/04/metadata">
    <alerts>
      ...
    </alerts>
    <fieldUpdates>
      ...
    </fieldUpdates>
    <flowActions>
      ...
    </flowActions>
    <outboundMessages>
      ...
    </outboundMessages>
    <rules>
      ...
    </rules>
    <tasks>
      ...
    </tasks>
</Workflow>

NOTE: Not all elements are represented here, and not all workflow files will contain all of these elements.

Answer 2

sfdx force:source:retrieve -m "WorkflowFieldUpdate:ObjectName.FieldupdateName"

example: sfdx force:source:retrieve -m "WorkflowFieldUpdate:SBQQ__Quote__c.Update_Approval_Status_to_Approved"

for alert replace "WorkflowAlert"
