GitVersion.Portable crashes on branch "development" GitVersion.yml has config for a branch named "development".

[ehvattum]

Given a repository with a branch called development, and this branch is checked out, and in the working directory, there is a valid GitVersion.yml file, that have explicit branch configuration for the branch development.

It seems like the "development" branch is found twice.(The regex is added the "search collection" that have the development branch explicitly added from config?)
The problem does not persist on other branch names.
The problem does persist even if we use the obsolete GitVersionConfig.yaml.

The GitVersion.yml in question:

The development configuration is listed twice. Once explcitly, and once as a regex.

[JakeGinnivan]

If you match the existing development regex it will be fine

assembly-informational-format: '{NugetVersion}'
branches:
  master:
    mode: ContinuousDelivery
    prevent-increment-of-merged-branch-version: true
    increment: Patch
  feature[/-]:
    mode: ContinuousDeployment
    increment: Patch
    track-merge-target: true
  dev(elop)?(ment)?$:
    mode: ContinuousDeployment
    tag: yolo
    increment: Patch
    track-merge-target: true

I don't think we have a way to ignore an existing default config, just update it's settings

[asbjornu]

@JakeGinnivan: But wouldn't it be less surprising if explicit config did override the default/implicit config? If we get a branch match on the explicit config, we shouldn't apply the default one to the same branch.

[ehvattum]

@JakeGinnivan Developers need to have intimate knowledge of that spesific regex to override it. That seems a bit opaque.
