After generating the APK files for my Android repo, I want the GitHub CI to send me an email to notify me that the artifacts are generated. So here I have an action to check if the APK name exists and regardless of the result, send me an email.

These artifacts are generated successfully but I get the emails saying they don't exist.

What went wrong in my script?

Answer 1

By the way, I have got a slightly different use case but needed to check if an artifact exists prior to doing some other steps.

Stumbled across this need and found no way of checking if some artifact exists. So created a new action: https://github.com/marketplace/actions/check-artifact-existence

You can add a new step that is going to expose and output denoting if an artifact exists or not by the given artifact name:

uses: xSAVIKx/artifact-exists-action@v0
id: check_coverage_artifact
with:
  name: 'coverage-artifact'

Then you can use steps.check_coverage_artifact.outputs.exists (true/false) in the conditions.

Answer 2

You're using app/build/outputs/apk/debug/app-debug.apk as an upload path but on the other hand you're checking app-debug.apk for existence.
