GitHub Action上传Unity构建产物为Release资产失败求助

核心问题 #

你遇到的报错源于三个关键问题：

1. game-ci/unity-builder不会自动将构建产物打包为Galactic.zip，你指定的/build/Galactic.zip路径根本不存在
2. GitHub Actions中使用绝对路径/build会指向Runner系统的根目录，而非仓库工作目录下的build文件夹
3. Release步骤中配置的所有文件路径均错误，导致无法定位到实际构建产物

修正后的YAML配置 #

以下是调整后的完整配置，解决了路径错误并优化了流程顺序：

  push:
    branches:
      - cd-testing
      - main
      - build-fix

      # 将构建产物打包为Zip（关键步骤）
      - name: Package Build into Zip
        run: zip -r Galactic.zip build/StandaloneWindows

      # 上传打包后的产物作为Artifact
      - uses: actions/upload-artifact@v2
        with:
          name: Galactic
          path: Galactic.zip

      - name: Unity - Return License
        uses: game-ci/unity-return-license@v2.0.0

          automatic_release_tag: "latest"
          prerelease: false
          title: "Development Build"
          files: Galactic.zip
            
      - name: Unity - Return License
        uses: game-ci/unity-return-license@v2.0.0

关键修改说明 #

1. 调整流程顺序：将测试步骤移至构建之前，先验证代码可测试性，避免无效构建浪费资源
2. 新增打包步骤：通过zip -r Galactic.zip build/StandaloneWindows将Unity构建的产物目录（StandaloneWindows为你指定的目标平台）打包为Galactic.zip
3. 修正路径配置：
   • 上传Artifact时指向打包后的Galactic.zip（而非整个build目录）
   • Release步骤中仅指定相对路径Galactic.zip，确保能正确定位到文件
4. 冗余License操作：保留了原有的License归还步骤，若觉得重复可合并（game-ci部分Action会自动处理License归还）

可选方案（无需手动打包） #

如果你不想打包成Zip，也可以直接将构建目录下的所有文件作为Release资产上传，只需修改Release步骤的files配置：

files: build/StandaloneWindows/**/*
