Metadata from Sandbox always retrieved with latest API version instead of following sourceApiVersion

Summary

Metadata Retrieval from a Sandbox always uses the latest API version (right now, 45.0) instead of using the sourceApiVersion specified in sfdx-project.json.

Steps To Reproduce:

1. Use an old API version in sfdx-project.json, for example:

{
  "packageDirectories": [
    {
      "path": "force-app",
      "default": true
    }
  ],
  "namespace": "",
  "sfdcLoginUrl": "https://login.salesforce.com",
  "sourceApiVersion": "43.0"
}

1. Authorize with a Sandbox

2. Right click on a custom object in the objects directory, click SFDX: Retrieve Source From Org

Expected result

The retrieved custom object should have their metadata structure based on the sourceApiVersion.

Actual result

The retrieved custom object has their metadata structure based on version 45.0. One thing that is easy to check is the existence of the enableLicensing node in the metadata XML, which does not exist in version 43.0.

Additional information

VS Code Version: 1.34.0

SFDX CLI Version: sfdx-cli/7.6.0-28071a499b

OS and version: Windows 10/Arch Linux

Just came across this issue. It’s pretty tough to deal with as the API version has a BIG impact and needs to be consistent across dev machines and CI environments.

@clairebianchi any chance this is in the backlog?
