隨便找一個開源的JAVA-Maven的在github專案。新增到gitlab上。

copy到gitlab上

• new project

• Git repository URL

• 點選create project

runner管理新的gitlabci-maven

maven的環境

 sudo gitlab-ci-multi-runner register

新建github-ci 檔案

# These are the default stages. You don't need to explicitly define them. But you could define any stages you need.
 

stages:
  - build
  - test
  - deploy

# This is the name of the job. You can choose it freely.
maven_build:
  # A job is always executed within a stage. If no stage is set, it defaults to 'test'
  stage: test
  # Since we require Maven for this job, we can restrict the job to runners with a certain tag. Of course, we need to configure a runner with the tag maven with a maven installation
 

  tags:
    - maven
  # Here you can execute arbitrate terminal commands.
  # If any of the commands returns a non zero exit code the job fails
  script:
    - echo "Building project with maven"
    - mvn verify

開始CI操作

修改.gitlab-ci.yml 就開啟了自動構建模式。

• 報錯了。 跟python當初構建的時候一樣。

Runner啟動的docker容器裡無法訪問到gitlab.example.com這個地址（能訪問到才怪）。這一般是由於我們的測試環境沒有使用域名導致的，gitlab論壇裡也不少人討論這個問題，如果你是在部署正式的gitlab環境，那你自然會有一個域名來使用。不過我這裡只是搭建測試環境，所以我使用了一種投機的方法：

修改Runner的/etc/gitlab-runner/config.toml檔案，在其中的[runner.docker]下增加：

sudo vi /etc/gitlab-runner/config.toml

成功了 重新Retry

6666 美滋滋，當初懟了個python現在java遇到這個問題知道咋解決了。

用的不是阿里雲，可能比較慢，不過是演示，之後想想辦法直接在腳本里面配置下私有庫的地址。

PS：這次主要給大家簡單的介紹下CI，還沒設計到CD。下次吧！
