Crashlytics task cannot be added to gradle tasks

Question

I installed Crashlytics plugin to Android Studio project, but the gradle task crashlyticsUploadDistributionDebug is not added to gradle tasks. How can I add to gradle tasks?

Installing Crashlytics is successed, but the command below is failed.

$ ./gradlew assembleDebug crashlyticsUploadDistributionDebug
The Task.leftShift(Closure) method has been deprecated and is scheduled to be removed in Gradle 5.0. Please use Task.doLast(Action) instead.

I don't know what is wrong.

Answer 1

I have configure develop, staging and production to productFlavors, so need to add productFlavor to the command.

Below is correct command.

./gradlew assembleDebug crashlyticsUploadDistribution[flavor]Debug

e.g.

$ ./gradlew assembleDebug crashlyticsUploadDistributionDevelopDebug
