Using Android Studio 3.3 Canary 11 with the gradle plugin version 3.3.0-alpha11. It throws the following error when trying to sync gradle 

WARNING: API 'variant.getExternalNativeBuildTasks()' is obsolete and has been 
replaced with 'variant.getExternalNativeBuildProviders()'.
It will be removed at the end of 2019.
For more information, see https://d.android.com/r/tools/task-configuration- 
avoidance
Affected Modules: app

Clicking on the error leads me to this line in the gradle file 

applicationVariants.all { variant ->
            variant.outputs.all {
                outputFileName = "${variant.name}-${variant.versionName}.apk"
            }
        }

What exactly do I need to change here?

apply plugin: 'com.google.gms.google-services'

I have skipped out a few constants and other sensitive information in the app/build.gradle file.

回答1:

In my case, I had to comment out io.fabric plugin:

apply plugin: 'com.android.application'
// apply plugin: 'io.fabric' <== this plugin causes the error

It happens after I updated Android Studio to 3.3.0.

I have sent a bug report to Firebase team about this issue.

For now, just downgrade to Android Studio 3.2.1.



回答2:

in application build.gradle , back to this version of gradle :

classpath 'com.android.tools.build:gradle:3.2.1'

temp solution until they fix it !



回答3:

Not sure what the actual issue is but commenting out the crashlytics related dependencies from the project solved issue.



回答4:

the issue-tracker might refer to "lazy task configuration" -

that's at least what task configuration avoidance suggests.

but one possibly can prevent the access to this obsolete method of BaseVariantImpl, when variant.outputs.all won't access that method (internally) - or when checks can prevent the access; or when accessing the variant by it's name; or somehow disable the external native build tasks for the variant. also see the single-variant project sync option, which rather seems related.

or wait for build-tools 3.3.0-alpha12 or 3.3.0-beta1 ...this is not even a release candidate, therefore investing to much time might be pointless - except using it to file another bug-report.

the new quick feedback button still looks the most promising.



回答5:

If commenting out io.fabric on the app gradle file worked for you temporarily 

//apply plugin: 'io.fabric'

Then upgrading your fabric gradle dependencies on the Project gradle file will permanently solve the issue:

classpath 'io.fabric.tools:gradle:1.27.0'

NB: this doesn’t remove the warnings but let you use Crashlytics with AS3.3+



回答6:

When I opened the project, I pressed the Run migrations button appeared on the right bottom corner from Android Studio. A migration was performed and the problem was solve without commenting out the Crashlytics dependency.



回答7:

Changing source compatibility in module build.gradle file to Java 8 fixes the issue

compileOptions {
    sourceCompatibility 1.8
    targetCompatibility 1.8
}

Be sure to rebuild the project after adding those lines



回答8:

I also couldn't start the project after updating Android Studio. But after deleting the .gradle, .idea, build folders and re-importing the project, everything worked, but the warning still remains.



回答9:

this will fix the error : On the taskbar click Tools->Kotlin->Configure Kotlin in Project



回答10:

Build log prints how to debug this, particularly you need to run build with -Pandroid.debug.obsoleteApi=true, that'll print stack-trace of call to deprecated API and you'll be able to figure which plugin/code calls it.

If it ends up being your code — use new Provider API (read Lazy Task Configuration doc)

If it comes from other plugin — report to them with stack-trace and warning message and maybe submit a patch. As in this case its related to io.fabric issue.



回答11:

For those who need to keep the Fabric plugin applied, the temporary solution is to go back to the previous version of the gradle at the project level.

Change the classpath version to com.android.tools.build:gradle:3.2.1.



回答12:

In my case, I needed to use io.fabric plugin, and the solution was, to update to the latest fabric tools gradle version:

classpath 'com.android.tools.build:gradle:3.3.0'
classpath 'io.fabric.tools:gradle:1.27.0'
