travis-ci - 未在 Travis CI 上使用 Matrix 时“未设置环境变量”

问题描述

我们正在削减对在 Travis CI 上测试 ARM64的支持。我们也停止使用标准 Matrix 并转而专门使用include:以减少不需要的工作。避免matrix:和使用include:可以节省 25 到 50 个不需要的工作。

更改的测试结果可在此处获得。大约 8 个作业在配置中失败，并出现错误“未设置环境变量”：

在此处输入图像描述

我们认为这些工作来自osx_image: xcode10.1. .travis.yml看来不需要的工作是osx_image应用到的结果{Linux,OS X} x {GCC,Clang} x {amd64,arm64}。

我们不知道如何停止这些工作或如何解决它们。

我们如何修复“未设置环境变量”失败的作业？

这里是相关的部分.travis.yml。

解决方案

我们认为这些工作来自 osx_image: xcode10.1 in .travis.yml

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这些工作来自哪里，除了它是matrix:我们试图避免的扩张的副产品。

我们如何修复“未设置环境变量”失败的作业？

修复是摆脱matrix:扩展，但它不是现成的信息。文档中当然没有说明。或者我们在文档中找不到它。

为了避免matrix:扩展，请去掉 , env, arch,os的所有全局键compiler。洞察力是，全局键触发矩阵扩展。矩阵扩展不依赖于matrix:或jobs:键的存在。

我们生成的 yml 文件如下所示。我们必须手动构建{env} x {arch} x {os} x {compiler}（我们已经在做的）的叉积。
