Question

我正在尝试使用 CodeBuild 在 AWS 上构建我的项目。我已将此 buildspec 文件放在根目录中。CodeBuild 能够读取文件，但无法继续进行。但是我在 CodeBuild 上遇到了以下错误。

CodeBuild 日志错误：

我的 buildspec.yaml 文件：

    version: 0.2

phases:
  install:
    runtime-versions:
      java: openjdk11

    commands:
      - apt-get update -y
      - apt-get install -y maven
      - pip3 install --upgrade awscli

  pre_build:
    commands:
      - sonar_host_url=""
      - sonar_project_key="$REPOSITORY_NAME"
      - sonar_username=$(aws secretsmanager get-secret-value --secret-id $SONARQUBE_USER_CREDENTIAL_SECRET | jq -r '.SecretString' | jq -r '.username')
      - sonar_password=$(aws secretsmanager get-secret-value --secret-id $SONARQUBE_USER_CREDENTIAL_SECRET | jq -r '.SecretString' | jq -r '.password')
      - git checkout $SOURCE_COMMIT

  build:
    commands:
      - builStatus=$(mvn install)
      - result=$(mvn clean sonar:sonar -Dsonar.projectKey=$sonar_project_key -Dsonar.host.url=$sonar_host_url -Dsonar.login=$sonar_username -Dsonar.password=$sonar_password)
      - echo $result

  post_build:
    commands:
      - echo $buildStatus
      - buildComment=$(echo "Status of project build phase : $buildStatus")
      - aws codecommit post-comment-for-pull-request --pull-request-id $PULL_REQUEST_ID --repository-name $REPOSITORY_NAME --before-commit-id $DESTINATION_COMMIT --after-commit-id $SOURCE_COMMIT --content "$buildComment"
      - sonar_link=$(echo $result | egrep -o "you can browse http://[^, ]+")
      - sonar_task_id=$(echo $result | egrep -o "task\?id=[^ ]+" | cut -d'=' -f2)

根据评论，问题是在phase : $build.

yaml遇到空格时会出现一些问题，:如以下 GitHub 问题所示：

• 字符串包含冒号 + 空格时出现 YAML 语法错误
