gitlab CI / CD在构建之前失败

Question

我是gitlab的新手，在尝试构建时遇到问题。

这是我到gitlab的网址：http://localhost/root/mytest，我在Linux虚拟机中安装了gitlab。

这是我的gitlab-ci.yml

import * as RNIap from 'react-native-iap';

const itemSkus = Platform.select({
  ios: ['productid1', 'productid2'],
  android: ['productid1', 'productid2'],
});

...
componentDidMount() {
  RNIap.initConnection().then(conn => {
    // conn is true
    RNIap.getProducts(itemSkus)
      .then(res => {
        // res is []
      })
      .catch(err => {
        // no err
      });
  });
}
...

这是工作cmd

        - echo "Building"
        - mkdir build

        paths:
            - ./target/*.war
    only:
        - master



deploy_staging:
    stage: deploy
    tags: 
        - my_tags
    script:
        - echo "Deploy to staging server"
        - "mvn -X install tomcat7:deploy"
    environment:
        name: staging
        url: http://localhost:88
    artifacts:
        paths:
            - target/*.war    
    only:
        - master

我真的不明白为什么会失败，为什么是/builds/project-2/.git/而不是/builds/root/mytest.git。

非常感谢您。
