如何通过Bitbucket-pipeline.yml按文件夹提交执行对应构建部署步骤？

完全可行，Bitbucket Pipelines提供了changesets功能，可以精准控制只有特定文件夹有提交变更时，才执行对应的流水线步骤。以下是修改后的bitbucket-pipeline.yml配置：

pipelines:
  branches:
    master: 
      - step:
          name: 'Frontend Build'
          image: node:16.4.2
          # 仅当myfrontend目录下有文件变更时执行此步骤
          changesets:
            - 'myfrontend/**'
          script:
            - cd myfrontend
            - npm install
      - step:
          name: 'Backend Build and Package'
          image: maven:3.8.3-openjdk-17
          # 仅当myfolder或mybackend目录下有文件变更时执行此步骤
          changesets:
            - 'myfolder/**'
            - 'mybackend/**'
          script:
            - cd myfolder
            - mvn clean package
          artifacts:
            - mybackend/target/mybackend-0.0.1-SNAPSHOT.jar
      - step:
          name: 'Deploy artifacts to Droplet'
          deployment: production
          # 仅当后端相关目录有变更时执行部署
          changesets:
            - 'myfolder/**'
            - 'mybackend/**'
          script:
            - pipe: atlassian/scp-deploy:0.3.3
              variables:
                USER: root
                SERVER: 138.138.138.138
                REMOTE_PATH: '/root/artifacts/target/'
                LOCAL_PATH: mybackend/target/mybackend-0.0.1-SNAPSHOT.jar
            - pipe: atlassian/scp-deploy:0.3.3
              variables:
                USER: root
                SERVER: 138.138.138.138
                REMOTE_PATH: '/root/artifacts'
                LOCAL_PATH: mybackend/Dockerfile
            - pipe: atlassian/scp-deploy:0.3.3
              variables:
                USER: root
                SERVER: 138.138.138.138
                REMOTE_PATH: '/root/automation-temp-folder'
                LOCAL_PATH: mybackend/README.MD

关键说明： #

• changesets字段用来指定触发步骤的文件路径匹配规则，**表示匹配目录下所有文件及子目录
• 前端构建步骤仅在myfrontend目录有变更时执行，后端构建和部署步骤仅在myfolder或mybackend目录有变更时执行
• 后续如果需要启用前端部署，只需给前端部署步骤添加对应的changesets: ['myfrontend/**']即可
