【问题描述】：

我正在尝试构建一个 gitlab 管道以从 Java 应用程序构建一个 docker 映像。我有两个工件，我想在构建阶段之间传递...一个文件 (build_result.txt) 被发现已上传，但另一个文件 (chat.jar) 找不到。但是，这两个文件都在同一个目录中。将文件作为工件上传是否有大小或扩展名限制？

---

stages:

  - app-build
  - con-build

image: docker:latest
  
services:
  - docker:dind

variables:
  #Global variables
  GIT_SSL_NO_VERIFY: "true"
  DOCKER_DRIVER: overlay2

 #Application variables 
  APP_NAME: web
  APP_TAG: test

before_script:
  - echo "..."

after_script:
  - echo "..."

app-build:
  stage: app-build
  artifacts:
    when: always
    paths:
      - build_result.txt 
      - chat.jar
    expire_in: 2 days
  tags: 
    - dind
  script:
    - echo "BEFORE..."
    - apk --no-cache --update add maven git
    - apk --no-cache --update add openjdk11 --repository=http://dl-cdn.alpinelinux.org/alpine/edge/community

    - echo "DO..."
    - echo "building app..."| tee -a build_result.txt 
    - git clone https://github.com/callicoder/spring-boot-websocket-chat-demo.git /app
    - cd /app
    - mvn package | tee -a build_result.txt
    - cp target/websocket-demo-0.0.1-SNAPSHOT.jar /app/chat.jar
    - ls / 
    - ls /app 
    - ls /app/target

con-build:
  stage: con-build
  dependencies:
    - app-build
  tags: 
    - dind
  artifacts:
    when: always
    paths:
      - docker_build.txt
    expire_in: 2 days

  script:
    - echo "Place artifact for docker consumption"
    - mkdir -p /docker/files/app
    - cp chat.jar /docker/files/app/chat.jar
    - cd docker
    - docker build -t "$APP_NAME:$APP_TAG" . | tee -a docker_build.txt

我得到的输出是找不到chat.jar，但它在同一目录中......在构建阶段日志的末尾显示为警告，但下一个作业失败说它可以't find the file ...它如何找到一个文件而不是另一个文件？

第 1 步 - 记录。

【参考方案1】：

您正在创建一个docker_build.txt 文件，其内容为echo "building app..."| tee -a build_result.txt 但是您将目录更改为/app，然后创建另一个docker_build.txt，最后构建您的工件。

但是你看到你的第一个docker_build.txt 不是你的ls 命令，因为你的起始目录不是/ 而是CI_PROJECT_DIR predefined variable 提供的动态路径

此外，所有工件定义也与此路径相关，因此在移动您的 docker_build.txt 命令后，这应该可以工作：

  artifacts:
    when: always
    paths:
      - app/build_result.txt 
      - app/chat.jar
