如何在 cloudformation 中的 `!If` 条件中使用多行？

Question

我!If在 cloudformation 模板中使用条件。下面的代码具有在项目中ShouldAddWebHook添加或删除的条件。当我运行部署命令时，我收到此错误。为什么它抱怨条件？TriggersAWS::CodeBuild::Project!If

while scanning a simple key
  in "<unicode string>", line 93, column 7:
          !If
          ^ (line: 93)
could not find expected ':'
  in "<unicode string>", line 94, column 9:
            - ShouldAddWebHook
            ^ (line: 94)

下面是cloudformation模板：

Conditions:
    ShouldAddWebHook: !Equals [ !Ref ShouldAddWebHook, "true" ]

Resources:
  CodeBuildProjectDeployment:
    Type: AWS::CodeBuild::Project
    Properties:
      Name: test
      Artifacts:
        Type: NO_ARTIFACTS
      Environment:
        Type: LINUX_CONTAINER
        ComputeType: BUILD_GENERAL1_SMALL
        Image: aws/codebuild/amazonlinux2-x86_64-standard:2.0
      Source:
        Type: BITBUCKET
        Location: !Ref BitbucketCloneUrl
        GitCloneDepth: 26
        BuildSpec: buildspec.yml
      TimeoutInMinutes: 10
      BadgeEnabled: true
      !If
        - ShouldAddWebHook
        - Triggers:
            Webhook: true
            FilterGroups:
              - - Pattern: PUSH
                  Type: EVENT
        - !Ref "AWS::NoValue"

Your !If can't be "hanging" like this. It should be associated with some property. You can try the following:

Resources:
  CodeBuildProjectDeployment:
    Type: AWS::CodeBuild::Project
    Properties:
      Name: test
      Artifacts:
        Type: NO_ARTIFACTS
      Environment:
        Type: LINUX_CONTAINER
        ComputeType: BUILD_GENERAL1_SMALL
        Image: aws/codebuild/amazonlinux2-x86_64-standard:2.0
      Source:
        Type: BITBUCKET
        Location: !Ref BitbucketCloneUrl
        GitCloneDepth: 26
        BuildSpec: buildspec.yml
      TimeoutInMinutes: 10
      BadgeEnabled: true
      Triggers:
        !If
          - ShouldAddWebHook
          - Webhook: true
            FilterGroups:
              - - Pattern: PUSH
                  Type: EVENT
          - !Ref "AWS::NoValue"
