我们有用于夜间构建的CI服务器。我们还在 xamarin 生成的生成服务器上具有所需的依赖项。出于某种原因，本周发生了一些变化(我不知道是什么(，但现在在_UpdateAndroidResgen构建步骤中，aapt 正在定义两次属性，这导致构建由于某种原因失败。

我已经验证问题似乎出在构建运行器上，因为 4 天前通过的相同代码现在也因 aapt 错误而失败。还验证了android sdk和构建工具版本与以往相同。我尝试恢复，删除所有bin和obj文件夹以及xamarin缓存文件夹~\AppData\Local\Xamarin\我还重新安装了android构建工具。在这一点上真的非常难倒。
以前有人见过这个问题吗？
如果其他人遇到此问题 事实证明，这只是由于构建服务器空间不足。VCS 签出有足够的空间，但当 android 构建工具尝试创建的临时文件和缓存文件超过可用磁盘空间时，它们不会失败并显示有用的错误消息。
