Duplicate Class Error in kotlin gradle implementation - kotlin

Question

I get duplicate class errors as gradle implementation app's build.gradle file. But I don't know which implementation is actually a duplicate. How can i resolve this? Is there a better way like using bom for the dependencies?
plugins {
id 'com.android.application'
id 'org.jetbrains.kotlin.android'
}
android {
namespace 'com.example.bettehomes'
compileSdk 33
defaultConfig {
applicationId "com.example.bettehomes"
minSdk 25
targetSdk 33
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
vectorDrawables {
useSupportLibrary true
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
jvmTarget = '1.8'
}
buildFeatures {
compose true
}
composeOptions {
kotlinCompilerExtensionVersion compose_version
}
packagingOptions {
resources {
excludes += '/META-INF/{AL2.0,LGPL2.1}'
}
}
}
dependencies {
// Import the Compose BOM
implementation 'com.google.android.gms:play-services-maps:18.1.0'
implementation 'androidx.core:core-ktx:1.9.0'
implementation 'androidx.lifecycle:lifecycle-runtime-ktx:2.5.1'
implementation 'androidx.activity:activity-compose:1.7.0-alpha04'
implementation "androidx.compose.ui:ui-tooling:1.3.3"
implementation "androidx.compose.ui:ui-tooling-preview:1.3.3"
implementation 'androidx.compose.material3:material3:1.1.0-alpha04'
// Android Studio Preview Support
debugImplementation "androidx.compose.ui:ui-tooling:1.3.3"
//testImplementation 'junit:junit:4.13.2'
androidTestImplementation 'androidx.test.ext:junit:1.1.5'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.5.1'
androidTestImplementation "androidx.compose.ui:ui-test-junit4:1.4.0-alpha05"
debugImplementation "androidx.compose.ui:ui-test-manifest:1.3.3"
}

I had this issue today and used gradle dependencies to figure out the dependency tree
I figured out that a lib used a latest version of appcompat which used kotlin 1.8.0, a version that has this issue.
In my case the fix was to add the kotlinVersion manually:
buildscript {
ext {
buildToolsVersion = "32.0.0"
minSdkVersion = 21
compileSdkVersion = 33
targetSdkVersion = 32
androidXBrowser = "1.4.0"
kotlinVersion = "1.8.0"
}
...
}
