NoMethodError: undefined method `map' for nil:NilClass

[QuentinN42]

Running Arduino-CI/action@stable-1.x result in NoMethodError :

I use the default workflow :

name: Arduino_CI

on: [pull_request]

jobs:
  arduino_ci:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v2
      - uses: Arduino-CI/action@stable-1.x

And my project is ok for arduino-lint action :

CI-test/
├── CI-test.ino
├── examples
│   └── example.c
├── README.md
└── test
    └── test.c

But I have always this issue :

================================================================================

Ok solved, just follow the structure of an arduino porject inside examples :

Hi @QuentinN42, thanks for reporting this! Even though your structure may not have been correct, that's no reason for the arduino_ci runner to crash.

I think I may have encountered this and fixed it locally, but I am going to reopen your issue until I get it into a pull request.

[QuentinN42]

I think the bug come from line 135 of /lib/arduino_ci/cpp_library.rb :
If info["library"]["examples"] is nil map will crash.

PS : I don't code in ruby, just fluent in stackoverflow 😄.

Yup, I have it here 7607915

[QuentinN42]

Nice !
When do you think this will be merged into a stable release ?

I just want to get the config overrides done as part of https://github.com/Arduino-CI/arduino_ci/milestone/11 and then I should be in good shape
