Execution failed for task ‘:app:uploadCrashlyticsMappingFileRelease

新版本的Firebase crash 库打混淆后的正式环境包会报错：

Execution failed for task ':app:uploadCrashlyticsMappingFileRelease

Caused by: java.lang.IllegalArgumentException: Host name may not be empty

解决方案：

在build.gradle  android{}中加入：

  gradle.taskGraph.whenReady {
        tasks.each { task ->
            if (task.name.contains("uploadCrashlyticsMappingFileRelease")) {
                task.enabled = false
            }
        }
    }
