Issue Summary

Pattern Match Labelling is not working with Bamboo Specs YAML when the Regex Pattern field is empty even though the field description says "Leave blank to label every build". Leaving that field blank works fine for plans that are not managed by Specs.

This is reproducible on Data Center: Yes.

Steps to Reproduce

1. Create a linked repository in Bamboo pointing to a repository type that supports Bamboo Specs (e.g. Bitbucket Server or Data Center).
   • Enable Bamboo Specs in the repository configuration and give it the following access Project creation allowed, Access all projects and Access all repositories.
2. Create a project in Bamboo named Test with key TEST.
3. Create a bamboo-specs folder inside your repository's root and the bamboo.yaml file inside with the following content:
   <repository-root>/bamboo-specs/bamboo.yaml

   ---
   version: 2
   plan:
     project-key: TEST
     key: PLAN
     name: Plan
   stages:
   - Default Stage:
       manual: false
       final: false
       jobs:
       - Default Job
   Default Job:
     key: JOB1
     other:
       all-other-apps:
         custom:
           auto:
             label: test
           buildHangingConfig.enabled: 'false'
     tasks:
     - script:
         interpreter: SHELL
         scripts:
         - echo hello world
     artifact-subscriptions: []
   notifications: []
   labels: []
   dependencies:
     require-all-stages-passing: false
     enabled-for-branches: true
     block-strategy: none
     plans: []
   other:
     concurrent-build-plugin: system-default
   

4. This will create a plan called Plan under the Test project. You should see one Specs update and one build triggered for TEST-PLAN at this stage.

Expected Results

The build should contain a label named test.

Actual Results

The build does not contain any labels.

Workaround

Add the regex field to your YAML file. If you're looking to label all builds you can use the following regex (otherwise customize the regex to meet your needs):

regex: .*

Following the example above you should end up with:

...
Default Job:
  key: JOB1
  other:
    all-other-apps:
      custom:
        auto:
          label: test
          regex: .*
        buildHangingConfig.enabled: 'false'
...
