Generator fails without error message

[puelocesar]

Description of the bug

When running dart run build_runner build --delete-conflicting-outputs -v, it fails with a [SEVERE] message, but no error message:

dart run build_runner build --delete-conflicting-outputs -v
Building package executable... (3.4s)
Built build_runner:build_runner.
[INFO] Entrypoint:Generating build script...

[SEVERE] openapi_generator on lib/open_api_config.dart (cached):


[SEVERE] Build:
Failed after 54ms

Steps to reproduce

My configuration looks like this:

@Openapi(
  additionalProperties: AdditionalProperties(
    pubName: 'my_api',
    pubAuthor: 'MyAuthor',
  ),
  inputSpecFile: 'openapi.json',
  generatorName: Generator.dio,
  outputDirectory: 'packages/my_api',
)
class MyApiGeneratorConfig extends OpenapiGeneratorConfig {}

And I'm running it like this:
dart run build_runner build --delete-conflicting-outputs -v

Expected behavior

If there's something wrong with my openapi spec, of something wrong with my configuration, I expect to see error messages telling me why the generation failed.

Update, I deleted my generated folder and run using flutter pub run build_runner build --delete-conflicting-outputs - instead of dart, and now I get this error right after everything was generated correctly:

Hi, can you share your openapi.json. Or try if you can reproduce the error with the example code

[gibahjoe]

Hi, upon further investigation, this was a severe log that was erroneously left in the release so everything should still work fine (its just logging error when there is no error). Please confirm that everything still genarates fine (if there are other issues, let me know). I will release a minor update in the next few hours and close this issue.

[thomasgi1]

At least from my point of view I can confirm that everything still generates fine. However, more annoying than the severe log is the fact that the generator's return value is not 0. That behaviour breaks all automated builds, which rely on a correct return value of the programs called. For now we have to ignore the return value of the dart run build_runner build call in order to complete the automated build. Of course, ignoring the return value will cause more trouble in the future, if there is a real error in our OpenAPI yaml file.

[gibahjoe]

@thomasgi1 I don't believe this log should cause what you are experiencing.

I have released the patch to remove the log, please check it out. If it is still happening , please share your logs and a minimal openapi spec that reproduces the issue.

[thomasgi1]

I tested your patch. It fixes the problem. Thank you for that.

I also double checked the return value behaviour of version 4.11.0. That old version definitely returns an error code != 0. However, in version 4.11.1 the error code is 0 again.
