build_runner 2.1.7/2.1.8 causes code generation to fail with several InconsistentAnalysisExceptions

[Pante]

• Dart version: 2.16.1
• Flutter version: 2.10.3
• Package used: build_runner: ^2.1.7
• Platforms: Windows & Linux (not tested on MacOS)

After upgrading build_runner from 2.1.6 to 2.1.7/2.1.8, the following combination of packages seems to cause code generation to fail with several InconsistentAnalysisExceptions. Downgrading to 2.1.6 and cleaning build_runner's cache resolves the problem.

The packages (taken from pubspec.lock):

auto_route:
  dependency: "direct main"
  description:
    name: auto_route
    url: "https://pub.dartlang.org"
  source: hosted
  version: "3.2.4"

auto_route_generator:
  dependency: "direct dev"
  description:
    name: auto_route_generator
    url: "https://pub.dartlang.org"
  source: hosted
  version: "3.2.3"

build_runner:
  dependency: "direct dev"
  description:
    name: build_runner
    url: "https://pub.dartlang.org"
  source: hosted
  version: "2.1.8"

mockito:
  dependency: "direct dev"
  description:
    name: mockito
    url: "https://pub.dartlang.org"
  source: hosted
  version: "5.1.0"

Causes the code generation to fail with the following logs:

Same here except downgrading to 2.1.6 doesn't resolve the issue. 🤔

Have the same issue. looks like there were no changes on build_runner, but it depends on so many packages. maybe a problem with them?

[Hoang-Nguyenn]

same issue now :( wait for response

[TEMPORARY SOLUTION]

Scanning through the dependencies I saw that analyzer (3.4.0) was updated recently, reverting to the previous version of the package fixes build_runner code generation.

You can get around this issue for now with:

dependency_overrides:
  analyzer: 3.3.1

Linking pull request 3269.

I downgraded to build_runner 2.1.5 and I have analyzer 2.8.0 that works

PS: I might've jinxed it:

Confirmed, this works! Thanks @Petri-Oosthuizen

The best solution for now is as suggested to pin analyzer to 3.3.1:

dependency_overrides:
  analyzer: 3.3.1

Hoping to get a revert of 3.4.0 published until we can figure out the best resolution.

[jakemac53]

It looks like this should be resolved in analyzer: 3.4.1. I will close for now but if anybody is still experiencing issues please comment and let us know.

A melhor solução por enquanto é sugerida para fixar o analisador em 3.3.1:

dependency_overrides :
   analisador : 3.3.1

Esperando obter uma reversão de 3.4.0 publicado até que possamos descobrir a melhor resolução.

Pra mim, resolveu o problema.
