`EXCEPTION: undefined method '[]' for nil` in release candidate

[Julian-Wollersberger]

I was very excited to try out the release candidate, but sadly, I couldn't get it to work.

When I try to run any ceedling command in my project, I get the following error:
EXCEPTION: undefined method '[]' for nil

I have tried it with two ruby versions, deleted stuff from the project config, and tried it with an empty project. As long as the minimal things are configured, it fails with that error. In a project created with ceedling new, it works though.

My only suspicion is that my project was created with ceedling 0.30.0 and somehow messed with the environment.

Full output:

ceedling --verbosity obnoxious test:all

I don't know to to make ruby emit a full stack trace here.

Hi, @Julian-Wollersberger. Thank you so much for this report. Could you run ceedling --verbosity debug test:all and post the full backtrace. That'll tell us where the problem is.

Of course:

Following that stack trace, I added this to my project file:

:test_build:
  :use_assembly: FALSE

:cmock:
  :unity_helper_path: []

This gets me further into the validaton 👍

Now I can rework my option:foo stuff into mixins :)

Ah ha. Thank you for this. @Julian-Wollersberger, you helped uncover a subtle bug in the new and improved defaults handling!

[mkarlesky]

@Julian-Wollersberger I believe the most recent prerelease fixes the problem. You won't need the :test_build and :cmock settings you added to work around the bug.

I'm going to close this issue. Please reopen if the issue is not resolved.

[Julian-Wollersberger]

Yes, it works now. Thanks!
