Question

我们正在削减对测试ARM64 on Travis CI的支持。我们也停止使用标准矩阵，而改用排他的include:来减少不必要的工作。避免使用matrix:并使用include:可以节省25到50个不需要的作业。

更改的测试结果可用here。大约8个作业在配置中失败，错误为“未设置环境变量” ：

我们认为工作来自osx_image: xcode10.1中的.travis.yml。似乎不需要的作业是osx_image应用于{Linux,OS X} x {GCC,Clang} x {amd64,arm64}的结果。

我们不知道如何停止工作或如何解决这些问题。

我们如何解决“未设置环境变量” 失败的作业？

这是.travis.yml的相关部分。

Answer 1

我们认为工作来自osx_image：.travis.yml中的xcode10.1

这是不正确的。我们删除了全局密钥osx_image，但问题仍然存在。

但是我们仍然不太了解工作来自何处，除了它是matrix:扩张的副产品之外，我们试图避免这种扩张。

我们如何解决“未设置环境变量”故障的作业？

解决方法是摆脱matrix:扩展，但是它不是一时可用的信息。它当然没有在文档中说明。或者我们在文档中找不到它。

为避免matrix:扩展，请删除env，arch，os，compiler的所有全局键。洞察力在于，全局键会触发矩阵扩展。矩阵扩展不取决于matrix:或jobs:键的存在。

Our resulting yml file looks like the following。我们必须手动构建{env} x {arch} x {os} x {compiler}的叉积（我们已经在做）。

jobs:是matrix:的别名，因此使用jobs.include代替matrix.include不会达到预期的效果。另请参见Travis YML Schema。

在Travis CI上不使用Matrix时“未设置环境变量”
