为什么我在将模式添加到文件的拉取请求中收到 Travis CI 错误？

Question

我是 Github 的新手。我通常不编程，但我正在尝试为此处的 Google Code-In 做些事情。我提交了一个pull request with several changes to xsf/xeps on Github, but I'm getting an error with Travis CI。带有 TCI 的日志结尾如下所示：

unable to parse xep-0363.xml

Done. Your build exited with 1.

The command "make all" exited with 2. 和 The command "echo "lint,$(xmllint --nonet --noout --noent --loaddtd --valid *.xml 2>&1 | wc -l)" | ./git-ratchet check -v" exited with 50. 行是红色的。

这是怎么回事？

好的，我正在编辑它以添加我已经尝试了@melpomene 在他们下面的回答中建议的内容。但是，我已经尝试删除该行 4 次，然后重新压缩提交，并且它不断重新出现。我该如何解决这个问题？

根据the Travis configuration of that build：

{
  "addons": {
    "apt": {
      "packages": [
        "xsltproc",
        "libxml2-utils"
      ]
    }
  },
  "before_install": [
    "wget -O git-ratchet https://github.com/iangrunert/git-ratchet/releases/download/v0.3.1/linux_amd64_git-ratchet",
    "chmod +x git-ratchet",
    "git fetch https://github.com/xsf/xeps.git refs/notes/*:refs/notes/*"
  ],
  "script": [
    "make all",
    "echo \"lint,$(xmllint --nonet --noout --noent --loaddtd --valid *.xml 2>&1 | wc -l)\" | ./git-ratchet check -v"
  ],
  "language": "ruby",
  "group": "stable",
  "dist": "precise",
  "os": "linux"
}

... 直接来自 that repo's .travis.yml:

addons:
  apt:
    packages:
      - xsltproc
      - libxml2-utils
before_install:
  - wget -O git-ratchet https://github.com/iangrunert/git-ratchet/releases/download/v0.3.1/linux_amd64_git-ratchet
  - chmod +x git-ratchet
  - git fetch https://github.com/xsf/xeps.git refs/notes/*:refs/notes/*
script:
  - make all
  - echo "lint,$(xmllint --nonet --noout --noent --loaddtd --valid *.xml 2>&1 | wc -l)" | ./git-ratchet check -v

有人通过设置 script 键获得了 customized the build step。

script 的值可以是单个 shell 命令，也可以是要由 travis 执行的 shell 命令列表。它们都是运行，但如果它们中的任何一个失败（通过返回非零退出状态），整个构建将被视为失败。

红线来自 Travis，告诉您哪个命令失败以及它的退出状态是什么。

至于这些命令的实际作用以及错误的含义，这取决于项目。我不熟悉这个，但失败前的最后几行输出是：

xep-0363.xml:249: parser error : XML declaration allowed only at the start of the document    
 <?xml version='1.0' encoding='UTF-8'?>    
      ^    
xep-0363.xml:249: parser error : XML declaration allowed only at the start of the document    
 <?xml version='1.0' encoding='UTF-8'?>    
      ^    
unable to parse xep-0363.xml    
make: *** [build/xep-0363.html] Error 6

确实 your commit 在文件中间引入了 <?xml ...?> 行，所以这可能是破坏构建的原因。
