WARNING: API 'variant.getJavaCompile()' is obsolete and has been replaced with 'variant.getJavaCompileProvider()'
AndroidAndroid StudioCompilationAndroid Gradle-PluginGoogle FabricAndroid Problem Overview
Suddenly when Syncing Gradle, I get this error:
> WARNING: API 'variant.getJavaCompile()' is obsolete and has been > replaced with 'variant.getJavaCompileProvider()'. > 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
I've got this build.gradle
for the app module:
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'com.google.gms.google-services'
apply plugin: 'io.fabric'
android {
compileSdkVersion 28
buildToolsVersion "28.0.2"
defaultConfig {
applicationId "..."
minSdkVersion 21
targetSdkVersion 28
versionCode 1
versionName "..."
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
versionNameSuffix = version_suffix
[...]
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
[...]
}
debug {

}
}
}
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.2.61"
implementation 'androidx.appcompat:appcompat:1.0.0-rc02'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'

androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0-alpha4'
implementation 'com.google.android.material:material:1.0.0-rc02'
[...]
}
I can compile the app correctly, but it's a bit bothering, and as I see it, something will stop working at the end of 2019. Any ideas of what is it and how to solve it?

I face this issue after updating to 3.3.0
If you are not doing what error states in gradle file, it is some plugin that still didn't update to the newer API that cause this. To figure out which plugin is it do the following (as explained in "Better debug info when using obsolete API" of 3.3.0 announcement):
- Add 'android.debug.obsoleteApi=true' to your gradle.properties file which will log error with a more details
- Try again and read log details. There will be a trace of "problematic" plugin
- When you identify, try to disable it and see if issue is gone, just to be sure
- go to github page of plugin and create issue which will contain detailed log and clear description, so you help developers fix it for everyone faster
- be patient while they fix it, or you fix it and create PR for devs
Hope it helps others

This issue is fixed now with update Fabric Gradle version 1.30.0:
Update release: March 19, 2019
Please see this Link: https://docs.fabric.io/android/changelog.html#march-15-2019
Please update your classpath dependency in project level Gradle:
buildscript {
// ... repositories, etc. ...
dependencies {
// ...other dependencies ...
classpath 'io.fabric.tools:gradle:1.30.0'
}
}

In my case, it was caused from gms services 4.3.0. So i had to change it to:
com.google.gms:google-services:4.2.0
I have found this by running:
gradlew sync -Pandroid.debug.obsoleteApi=true
in terminal. Go to view -> tool windows -> Terminal in Android Studio.

This is just a warning and it will probably be fixed before 2019 with plugin updates so don't worry about it. I would recommend you to use compatible versions of your plugins and gradle.
You can check your plugin version and gradle version here for better experience and performance.
https://developer.android.com/studio/releases/gradle-plugin
Try using the stable versions for a smooth and warning/error free code.
Solution 5 - Android
I also faced the same issue. And after searching for a while, I figured it out that the warning was arising because of using the latest version of google-services
plugin (version 4.3.0). I was using this plugin for Firebase functionalities in my application by the way.
All I did was to downgrade my google-services
plugin in buildscript in the build.gradle(Project) level file as follows:
buildscript{
dependencies {
// From =>
classpath 'com.google.gms:google-services:4.3.0'
// To =>
classpath 'com.google.gms:google-services:4.2.0'
}
}

-
Add
android.debug.obsoleteApi=true
to yourgradle.properties
. It will show you which modules is affected by your the warning log. -
Update these deprecated functions.
-
variant.javaCompile
tovariant.javaCompileProvider
-
variant.javaCompile.destinationDir
tovariant.javaCompileProvider.get().destinationDir
Solution 7 - Android
Change your Google Services version from your build.gradle
:
dependencies {
classpath 'com.google.gms:google-services:4.2.0'
}
Solution 8 - Android
This is a warning spit out by build tools for two reasons.
-
One of the plugin is relying on Task instead of TaskProvider, there is nothing much we can do.
-
You have configured usage of task, where as it supports TaskProvider.
WARNING: API 'variant.getGenerateBuildConfig()' is obsolete and has been replaced with 'variant.getGenerateBuildConfigProvider()'. It will be removed at the end of 2019. For more information, see https://d.android.com/r/tools/task-configuration-avoidance
WARNING: API 'variant.getJavaCompile()' is obsolete and has been replaced with 'variant.getJavaCompileProvider()'. It will be removed at the end of 2019. For more information, see https://d.android.com/r/tools/task-configuration-avoidance
WARNING: API 'variant.getMergeResources()' is obsolete and has been replaced with 'variant.getMergeResourcesProvider()'. It will be removed at the end of 2019. For more information, see https://d.android.com/r/tools/task-configuration-avoidance
Look out for snippets as below & update.
android {
<library|application>Variants.all { variant ->
/* Disable Generating Build config */
// variant.generateBuildConfig.enabled = true // <- Deprecated
variant.generateBuildConfigProvider.configure {
it.enabled = true // Replacement
}
}
}
Similarly, find usages of 'variant.getJavaCompile()'
or 'variant.javaCompile'
, 'variant.getMergeResources()'
or 'variant.mergeResources'
. Replace as above.

Upgrading the Kotlin (Plugin and stdLib) version to 1.3.1 solved that warning in my case. Update the Kotlin version in whole project by replacing existing Kotlin version with :
ext.kotlin_version = '1.3.50'
Solution 10 - Android
Downgrading the version of Gradle worked for me:
classpath 'com.android.tools.build:gradle:3.2.0'
Solution 11 - Android
Go back from classpath 'com.android.tools.build:gradle:3.3.0-alpha13' to classpath 'com.android.tools.build:gradle:3.2.0'
this worked for me
Solution 12 - Android
Updating gradle to gradle:3.3.0
The default 'assemble' task only applies to normal variants. Add test variants as well.
android.testVariants.all { variant ->
tasks.getByName('assemble').dependsOn variant.getAssembleProvider()
}
also comment apply fabric
//apply plugin: 'io.fabric'
Solution 13 - Android
Update fabric plugin to the latest in project level Gradle file (not app level). In my case, this line solved the problem
classpath 'io.fabric.tools:gradle:1.25.4'
to
classpath 'io.fabric.tools:gradle:1.29.0'
Solution 14 - Android
In my case
build.gradle(Project)
was
ext.kotlin_version = '1.2.71'
updated to
ext.kotlin_version = '1.3.0'
looks problem has gone for now
Solution 15 - Android
In my case, I had to comment out com.google.firebase.firebase-crash
plugin:
apply plugin: 'com.android.application'
// apply plugin: 'com.google.firebase.firebase-crash' <== this plugin causes the error
It is a bug since Android Studio 3.3.0
Solution 16 - Android
if I remove this row from application gradle
:
apply plugin: 'io.fabric'
error will not appear anymore.
Solution 17 - Android
When the plugin detects that you're using an API that's no longer supported, it can now provide more-detailed information to help you determine where that API is being used. To see the additional info, you need to include the following in your project's gradle.properties file:
android.debug.obsoleteApi=true
Solution 18 - Android
> Migrate your project to androidX.
dependencies are upgraded to androidX. so if you want to use androidX contents migrate your project to androidX.
With Android Studio 3.2 and higher, you can quickly migrate an existing project to use AndroidX by selecting Refactor > Migrate to AndroidX from the menu bar.
> Downgrading dependencies may fix your problem this time - but not recommended
Solution 19 - Android
This fixed my problem.. All I needed to do was to downgrade my google-services plugin in buildscript in the build.gradle(Project) level file as follows
buildscript{
dependencies {
// From =>
classpath 'com.google.gms:google-services:4.3.0'
// To =>
classpath 'com.google.gms:google-services:4.2.0'
// Add dependency
classpath 'io.fabric.tools:gradle:1.28.1'
}
}

Here a temporary workaround, If you are using room just upgrade to 1.1.0 or higher
implementation "android.arch.persistence.room:runtime:1.1.0"
it removes this warning for me.
Solution 21 - Android
keep you Project(not app) Build.gradle dependncies classpath version code is new
dependencies {
classpath 'com.android.tools.build:gradle:3.5.0-beta01'
classpath 'com.novoda:bintray-release:0.8.1'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
Solution 22 - Android
This is a popular question. If you do not use these methods, the solution is updating the libraries. Please update your kotlin version, and all your dependencies like fabric, protobuf etc. If you are sure that you have updated everything, try asking the author of the library.
Solution 23 - Android
Upgrading protobuf-gradle-plugin to version 0.8.10 solved my problem. Replace your existing protobuf with
classpath 'gradle.plugin.com.google.protobuf:protobuf-gradle-plugin:0.8.10'
Solution 24 - Android
That's mostly due to libraries which are obsolete. To check for new updates manually, you should navigate to
> Analyze > "Run Inspection By Name"
That should be enough. Another option is to run a gradle dependency update using
./gradlew dependencyUpdates
that will produce a report like this:
:dependencyUpdates
------------------------------------------------------------
: Project Dependency Updates (report to plain text file)
------------------------------------------------------------
The following dependencies are using the latest milestone version:
- com.github.ben-manes:gradle-versions-plugin:0.15.0
The following dependencies have later milestone versions:
- com.google.auto.value:auto-value [1.4 -> 1.4.1]
- com.google.errorprone:error_prone_core [2.0.19 -> 2.0.21]
- com.google.guava:guava [21.0 -> 23.0-rc1]
- net.ltgt.gradle:gradle-apt-plugin [0.9 -> 0.10]
- net.ltgt.gradle:gradle-errorprone-plugin [0.0.10 -> 0.0.11]

upgrading the google services in project-level build.gradle
solved my problem.
After upgrading:
dependencies {
...
classpath 'com.google.gms:google-services:4.3.2'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}

I had same problem and it solved by defining kotlin gradle plugin version in build.gradle file.
change this
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
to
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.50{or latest version}"
Solution 27 - Android
In my case I followed this. Summary, in gradle app level: change this :
variant.outputs.all { output ->
variant.assemble.doLast {
....
}
}
to
variant.outputs.all { output ->
variant.getAssembleProvider().configure() {
it.doLast {
....
}
}
