Unable to specify coverage reports flags per file

[ssbarnea]

Current way to define flags forces them to apply to all files part of a single upload step. Ideally the flags should be per file and not per upload action.

This makes Github Actions definition much harder to manage as we are forced to add extra calls to the upload action, especially as GHA does not have any support for looping.

It would be far more flexible if we could so something like:

    - name: Upload coverage to Codecov
      uses: codecov/codecov-action@v4
      with:
        directory: ./coverage/reports/
        files: ./coverage1.xml:unit,./coverage2.xml:e2e,!./cache # <- note the `:flag` after file pattern.
        # flags: unit,e2e

Or maybe someone else has another idea?

Not totally sure about the intent... But I'm facing a similar issue. My issue is that with the current codecov action, I'm not able to upload coverage for each packages (flagged): ie: flag-lib1: coverage 90%, flag-lib2: coverage: 81%

I have a nodejs monorepo setup: https://github.com/belgattitude/httpx

.
└── packages
    │── assert
        └── coverage/clover.xml 
    │── dsn-parser
        └── coverage/clover.xml
    │── exception
        └── coverage/clover.xml
    └── plain-object
        └── coverage/clover.xml
- codecov.yml

In my codecov.yml, I've set up the flags for each packages

See here

I was expecting the codecov action to read paths assicated to the flags... but it actually doesn't.

So to be able to get covergae independently, I have to upload multiple times with each flags.

It would be nice to have a better way to do

PS: I have done it with the cli, but it does not work anymore (complains about missing token..., or rate limits)

Any progress on this please?

One year later and the situation is now worse, codecov complains in the UI about multiple flags being provided despite the fact that they own actions supports multiple ones.

Multiple flags detected. Please ensure one flag per upload.

This was caused https://github.com/codecov/gazebo/pull/3375 which apparently was on purpose but without mentioning exactly why or the fact that multiple flags are still supported by the action. I guess that the action should start failing if multiple flags are passed. A bit of incomplete implementation.
