Gradle - Null extracted folder for artifact: ResolvedArtifact

I've the following line in my gradle android project inside the module build.gradle

dependencies {
 // a lot of dependencies
 implementation 'org.tensorflow:tensorflow-lite-select-tf-ops:0.0.0-nightly-SNAPSHOT'
}

and it causes the gradle build to fail with the following error

Null extracted folder for artifact: ResolvedArtifact(componentIdentifier=org.tensorflow:tensorflow-lite-select-tf-ops:0.0.0-nightly-SNAPSHOT:20210331.060351-75, variantName=null, artifactFile=C:\Users\USER\.gradle\caches\modules-2\files-2.1\org.tensorflow\tensorflow-lite-select-tf-ops\0.0.0-nightly-SNAPSHOT\b03a88bda4ad93e6fefe285f9ea303d28433eacc\tensorflow-lite-select-tf-ops-0.0.0-nightly-SNAPSHOT.aar, extractedFolder=null, dependencyType=ANDROID, isWrappedModule=false, buildMapping={__current_build__=C:\Users\USER\Desktop\Myapp2}, mavenCoordinatesCache=com.android.build.gradle.internal.ide.dependencies.MavenCoordinatesCacheBuildService$Inject@5c4450a)

I had the same implementation in a diffrent project and it worked but in this project this error keep on appearing.

what causes this error? and how can I fix it?

I solved this issue by upgrading AGP version from 4.2 to 7.0

In the build.gradle file:

    buildscript { 
    ext {
        agp_version = '7.0.0'
    }

    dependencies {
        classpath "com.android.tools.build:gradle:$agp_version"
    }
    }

After editing the path to AAR library, as mentioned by others (implementation...), I also had to specifically sync project with Gradle. From the meniu File -> Sync Project with Gradle files . In Android Studio Chipmunk 2021.2.1

implementation 'androidx.activity:activity:1.8.0'

Remove this line from gradle.build and resolve the issue

In my case I had to go to the equivalent folder:

C:\Users\USER\.gradle\caches\modules-2\files-2.1\org.tensorflow\tensorflow-lite-select-tf-ops

And delete it, then try to sync again, and worked.

In my case, an Artifact error was generated After Project migrated from Android to AndroidX

Error was

Null extracted folder for artifact: ResolvedArtifact(componentIdentifier=androidx.activity:activity:1.8.0, variantName=null, artifactFile=/home/mittal/.gradle/caches/modules-2/files-2.1/androidx.activity/activity/1.8.0/4266e2118d565daa20212d1726e11f41e1a4d0ca/activity-1.8.0.aar, extractedFolder=null, dependencyType=ANDROID, isWrappedModule=false, buildMapping={__current_build__=/home/mittal/StudioProjects/android/android-sdk}, mavenCoordinatesCache=com.android.build.gradle.internal.ide.dependencies.MavenCoordinatesCacheBuildService$Inject@6fbb61c0)

Excluding Activity library from material dependencies solved the error

    implementation ('com.google.android.material:material:1.10.0') {
    exclude group: 'androidx.activity', module: 'activity'
}

So if you are facing the artifact error then check the library mentioned in the error and Try removing that library may help you.

When importing arr/jar to AS, I have encountered this issue. My method is switching Project view to Project mode (not Android mode) and after that add aar/jar to libs folder (or any folder)

You must check the path well for example:

implementation(files("./src/libs/myfile.aar"))

or

implementation files("./src/libs/myfile.aar")

In my case I had to increase amount of RAM to 4096 in gradle.properties:

org.gradle.jvmargs=-Xmx4096M

After that project synced correctly.

Well, you can be more explicit like this.

implementation files("$rootProject.projectDir/libs/test.aar")

I got the error when I was adding unit-ads.aar . I changed this in my code and its works for me.

Old Code

implementation files('../libs/unity-ads.aar')

New Code

implementation files('libs/unity-ads.aar')
