[YAML] [Structure] [Suggestion] Use lists rather than maps

[JamesYeoman]

The current structure

dependencies:
- {groupId: ch.qos.logback, artifactId: logback-classic, version: '${logback.version}'}
- {groupId: ch.qos.logback, artifactId: logback-core, version: '${logback.version}'}

just doesn't look quite right. What I had imagined it as is something like this

dependencies:
  - groupId: ch.qos.logback
    artifactId: logback-classic
    version: ${logback.version}
  - groupId: ch.qos.logback
    artifactId: logback-core
    version: ${logback.version}

The use of lists rather than maps actually makes it easier to read (although, that is subjective).

Not sure how that is logic to imply groupId and artifactId but no version.

[mosabua]

If anything I can image:

dependencies:
  - groupId: ch.qos.logback
    artifactId: logback-classic
    version: ${logback.version}
  - groupId: ch.qos.logback
    artifactId: logback-core
    version: ${logback.version}

The implying was kinda just me over-DRYing. Your suggestion is basically what I was shooting for. I just tried to group the artifacts by common groupIds

I will update the OP now

EDIT
I have now updated it

Aren't these the same thing and both supported by YAML syntax?

[dragetd]

- {foo: bar, bleep: bloop}
- {foo2: bar, bleep2: bloop}

is equivalent to

- foo: bar
  bleep: bloop
- foo2: bar
  bleep2: bloop

Both are a list of mappings. The curly braces are just a short-form for writing a map. The YAML parser should treat both the same.

But by far my favorite way to write deps is using the id setting:

dependencies:
  - id: "org.springframework.boot:spring-boot-starter-web"
  - id: "org.mapstruct:mapstruct:1.4.2.Final"
