[release/9.0.1xx] Backport dotnet-install script from a941e34 - #9780
Merged
Conversation
Partial backport of #9761 Update `build-tools/xaprepare` to improve reliability when running `Step_InstallDotNetPreview`. `Step_InstallDotNetPreview` will cache e.g. `dotnet-install.sh` into `$HOME/android-archives`, but there was no logic to verify that it was still *valid*. We've been seeing some recurring build failures in **macOS > Build** such as: Downloading dotnet-install script... Warning: Using cached installation script found in '/Users/builder/android-archives/dotnet-install.sh' Discovering download URLs for dotnet SDK '10.0.100-preview.2.25102.3'...

The problem, though, is that .NET changed the CDN that is used in the past month, and that's not the correct URL.

Update `Step_InstallDotNetPreview` to try to install .NET potentially *twice*: the first time using the cached `dotnet-install.sh`, and *if that fails*, it tries again after downloading a *new* `dotnet-install.sh`. Hopefully this will fix the build failure on this machine! [0]: https://dotnetcli.azureedge.net/dotnet/Sdk/10.0.100-preview.2.25102.3/dotnet-sdk-10.0.100-preview.2.25102.3-osx-arm64.tar.gz
