included_file_parse_error

{0} in {1}({2}..{3})

The analyzer produces this diagnostic when the content of a file that is included into an analysis options file isn't valid YAML.

Given a file named shared.yaml that contains:

// %uri="shared.yaml"
analyzer:
  enable-experiment:
    - augmentations
  enable-experiment:
    - dot-shorthands

The following code produces this diagnostic because the included file isn't valid YAML: the analyzer map contains duplicate enable-experiment keys.

// %uri="analysis_options.yaml"
include: shared.yaml
analyzer:
  enable-experiment:
    - enhanced-parts

If the file is intended to be included, then correct the included file to be valid YAML:

// %uri="shared.yaml"
analyzer:
  enable-experiment:
    - augmentations
    - dot-shorthands

If the file isn't intended to be included, then remove the include key:

// %uri="analysis_options.yaml"
analyzer:
  enable-experiment:
    - enhanced-parts
