Usage

This recipe has required configuration parameters. Recipes with required configuration parameters cannot be activated directly. To activate this recipe you must create a new recipe which fills in the required parameters. In your rewrite.yml create a new recipe with a unique name. For example: com.yourorg.MergeYamlExample. Here's how you can define and customize such a recipe within your rewrite.yml:
rewrite.yml
---
type: specs.openrewrite.org/v1beta/recipe
name: com.yourorg.MergeYamlExample
displayName: Merge YAML snippet example
recipeList:
- org.openrewrite.yaml.MergeYaml:
key: $.metadata
yaml: labels:
label-one: "value-one"
acceptTheirs: null
objectIdentifyingProperty: name
Now that com.yourorg.MergeYamlExample has been defined activate it in your build file:
