azure-pipelines - 使用参数化的模板来避免代码重复会导致错误消息：“期望序列”(Using parameterized templates to avoid code duplicates leads to error message: 'A sequence was expected')

Question

For our build, I want to use a stage that is triggered for every push / pull request, with a limited number of parameter combinations in the build matrix.

(对于我们的构建，我想使用为每个推/拉请求触发的阶段，在构建矩阵中使用有限数量的参数组合。)

Another stage, which is executed nightly using a scheduled build, I want to use the full build matrix with all parameter combinations.

(另一个阶段是使用计划的构建每晚执行一次，我想将完整的构建矩阵与所有参数组合一起使用。)

Since Azure Pipelines does not support a compact representation of the build matrix , I would at least like to put the build matrix into a separate file, so that file is at least clearly arranged.

(由于Azure Pipelines 不支持生成矩阵的紧凑表示形式，因此我至少希望将生成矩阵放入一个单独的文件中，以便至少清楚地安排该文件。)

azure-pipelines.yml (the main file)

(azure-pipelines.yml （主文件）)

stages:
  - stage: ci_build_on_default_pool
    jobs:
      - template: tools/azure-pipelines/azure-jobs.yml

Answer 1

I recall encountering this issue when I first started using templates.

(我记得我第一次开始使用模板时遇到的这个问题。)

Im pretty sure it has to something to with the first step of a template has to be a task.

(我非常确定，模板的第一步一定要完成任务。)
