Open Spacetown opened 2 months ago

Description

We added Codacy to GCOVR CI as a future replacement for Codecov.

Uploading LCOV files is failing without a meaningful error message:

Environment

GitHup pipeline running on Ubuntu 22.04: https://github.com/gcovr/gcovr/actions/workflows/upload_coverage.yml

Expected Behavior

A error message which part of the file isn't accepted.

Actual Behavior

  1. The error message doesn't contain the problem:

    warn [ReportRules] Could not parse report, unrecognized report format (tried: LCOV)  - (ReportRules.scala:59)
  2. Accept files which follow the format description: https://github.com/linux-test-project/lcov/blob/07a1127c2b4390abf4a516e9763fb28a956a9ce4/man/geninfo.1#L989

Reproducible Test Case

Upload file https://github.com/gcovr/gcovr/blob/7.2/gcovr/tests/nested/reference/gcc-5/coverage.lcov
