Android 将特定构建警告视为错误，因此当 Crashlytics 映射文件上传失败时构建失败

Question

Our production builds are build on a build server that is behind a proxy and it's not always sure to have an internet connection. However when the upload of the Crashlytics mapping file fails it will only show a warning and the build still succeeds. I want to prevent that I miss this warning and upload the app in the store, because as a result I will get obfuscated stacktraces in the store.

That's why I was wandering if it's possible to treat this specific warning as an error so my build will fail. I have some other warnings during the Gradle build that I cannot solve at this time, so to treat all warnings as an error is not gonna work for me. This is the warning that is shown.

WARN - Crashlytics had a problem uploading the deobs file. Please check network connectivity and try again.

Thanks for the feedback, I shared this with the product team and this warning will be an error in the new Firebase Crashlytics SDKs when they release. among many other small changes and improvements: You can track progress on the status of the new SDKs here: https://get.fabric.io/roadmap .
