github - 复合运行步骤 GitHub 操作错误 : 'An action could not be found at the URI'

Question

我正在尝试在 GitHub 操作上使用复合运行步骤操作，如 here 所述，以便在不同的工作流程中重用它们。
但是，我收到错误:

An action could not be found at the URI 'https://api.github.com/repos/scripts/build_ubuntu/tarball/v1

我的主要工作流程( .github/workflows/BuildUbuntu.yml )如下:

[...]

jobs:
  ubuntu_build_appimage:
    name: Build MeshLab (Ubuntu - AppImage)
    runs-on: ubuntu-16.04

    steps:
    - uses: scripts/build_ubuntu@v1

[...]

复合步骤( .github/workflows/scripts/build_ubuntu/action.yml )如下:

runs:
  using: "composite"
  steps: 
  - uses: actions/checkout@v2
    with:
      submodules: true

  [other steps...]

我究竟做错了什么？

Answer 1

您的 工作流程 错误地引用了该操作。它正在寻找存储库 build_ubuntu用户/组织的scripts带标签 v1 .
您可以在本地引用它，因为它在同一个存储库中。

jobs:
  ubuntu_build_appimage:
    name: Build MeshLab (Ubuntu - AppImage)
    runs-on: ubuntu-16.04

    steps:
    - uses: ./.github/workflows/scripts/build_ubuntu

[...]

您的 行动缺少 name和 description元素。这些是根据 https://docs.github.com/en/actions/creating-actions/metadata-syntax-for-github-actions 所必需的.
此外，您不能使用 uses复合运行步骤操作中的步骤为 webknjaz在他的评论中指出。目前您只能使用 run具有以下子元素的步骤

What does composite run steps currently support?

For each run step in a composite action, we support:

• name
• id
• run
• env
• shell
• working-directory

In addition, we support mapping input and outputs throughout the action.

What does Composite Run Steps Not Support

We don't support setting conditionals, continue-on-error, timeout-minutes, "uses", and secrets on individual steps within a composite action right now.

(Note: we do support these attributes being set in workflows for a step that uses a composite run steps action)

(来源:https://github.com/actions/runner/issues/646)

name: "My composite action"
description: "Execute some run setps to do something"
runs:
  using: "composite"
  steps: 
  - run: |
      echo do something
      echo and do something else
