    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Whenever i build the app in Android Studio, the files will be re-downloaded again. I have even tried to delete cache file. Any Solution?

Try to use compiler 1.4.0 and the kotlin plugin 1.8.0

My same problem occurred due to these 2 plugins

implementation 'androidx.lifecycle:lifecycle-livedata-ktx:2.6.1'
implementation 'androidx.lifecycle:lifecycle-viewmodel-ktx:2.6.1'

I encountered it by just downgrading from 2.6.1 to 2.5.1

Like below

implementation 'androidx.lifecycle:lifecycle-livedata-ktx:2.5.1'
implementation 'androidx.lifecycle:lifecycle-viewmodel-ktx:2.5.1'

If the above solution does not affect anything, try downgrading some plugins you just upgraded. It'll definitely resolve.

I hope it is helpful.

EDIT:

@Harshad faced an error with this plugin

implementation 'androidx.lifecycle:lifecycle-viewmodel-compose:2.6.1'

Resolved by downgrading that to 2.5.1 as below mentioned.

implementation 'androidx.lifecycle:lifecycle-viewmodel-compose:2.5.1'

That's awesome. Have been struggling with this one. In my case it was implementation 'androidx.lifecycle:lifecycle-viewmodel-compose:2.6.1' downgraded to 2.5.1

MDEV Over a year ago

@Harshad Yes, don't know why these 2.6.1 version is causing errors

I think this is caused by the alpha version of constraintlayout.

//Constraint Layout
implementation("androidx.constraintlayout:constraintlayout-compose:1.1.0-alpha06")

I had the same issue, when I downgraded the constraintlayout-compose version to 1.0.1 everything worked again.

In this case, even in new version

 implementation 'androidx.appcompat:appcompat:1.7.0-alpha02'

there is a same problem, so REMOVE alpha version

implementation 'androidx.appcompat:appcompat:1.6.1'

remove ...-alpha... from dependencies seems like the right idea

You can add this to your project dependencies

implementation(platform("org.jetbrains.kotlin:kotlin-bom:1.8.0"))
