new --codecoverage parameter in package build not showing up

Question

I'm running a package build on our packages to get the --codecoverage parameter like so:

sfdx force:package:version:create -p myPackage -w 100 -x -v DevHub  --json --codecoverage

This runs, and returns

But codecoverage isn't shown at all. Am I missing something here? This is when using sfdx-cli/7.73.1.

Answer 1

When you run the package version command with --codecoverage flag what happens is the code coverage is calculated in the backend.

You can then see the code coverage by listing the package versions for the package using the below command

sfdx force:package:version:list -p <packaged> --verbose
