nukeeper task succeeds even with failure

[OneCyrus]

the task doesn't report a failure or warning even when it failed. at least it should report this as a warning.

I think should be fixed within NuKeeper itself. It should return a exitcode -1 which causes a task fail

[OneCyrus]

this looks like an issue how nukeeper handles branches. we stil have this issue and it looks like the repro is:

1. let nukeeper create a PR + branch for a dependency update in Azure DevOPs
2. go into the PR and click "abandon" and "delete branch"
3. let nukeeper try and create the same update again -> it fails with the issue above.

probably the way Azure DevOps deletes the branch is not compatible with how nukeeper checks if the branch already exists.

P.S. and yes, the issue should probably be moved to the nukeeper repo

ok finally pin pointed the issue. the problem is with the local only branches which nukeeper creates. those won't be deleted and stay there forever.

running git show-ref shows somehting like this:

adding e.g. a git branch -d nukeeper-update-Microsoft.AspNetCore.Mvc.Versioning.ApiExplorer-to-3.2.0 resolves the issue for this branch.

IMHO nukeeper should remove a local-only branch when it already exists

I solved this by making sure my pipeline starts with a clean repository (clean: resources):

jobs:
- job: NuKeeper
  displayName: Update dependencies
  continueOnError: "false"
  workspace:
    clean: resources
  steps:
  - task: nukeeper.nukeeper.nukeeper.NuKeeper@0
    displayName: NuKeeper
    inputs: 
      arguments: '--verbosity detailed'
  pool:
   name: "Default"

However yes, the pipeline is not failing on error.
