Introduction
A "Duplicate class" error can occur in a Jetpack Compose project when two or more dependencies contain the same class. This can happen when adding new dependencies to your project. To fix this issue, you need to identify which dependencies are causing the conflict and either remove one of them or exclude the conflicting class from one of the dependencies.
How this error was encounter:
While, working on a project, Android Studio recommend I update these dependencies that I mentioned below:
//build.gradle(Module:app)
implementation 'androidx.core:core-ktx:1.10.1'
implementation 'androidx.lifecycle:lifecycle-runtime-ktx:2.6.1'
implementation 'androidx.activity:activity-compose:1.7.1'
After the update, no error but when I try to run the project on My phone suddenly this error occurs
Execution failed for task ':app:checkDebugDuplicateClasses'.
it also includes this :
A failure occurred while executing com.android.build.gradle.internal.tasks.CheckDuplicatesRunnable

How I fix this Duplicate class error:
I just follow a small step. If you follow the same steps that I will mention below I guarantee you will not face this error again.
Step 1: Go to project explorer and click build.gradle(Project:<YOUR PROJECT NAME>).
Step 2: You see this
plugins {
id 'org.jetbrains.kotlin.android' version '1.7.20' apply false
}
here org.jetbrains.kotlin.android version in my case is 1.7.20. Now, change this version to the latest available Kotlin version, while writing this solution Kotlin version 1.8.21 and sync project.
Step 3: Re-Run your app on your device or Emulator.
Step 4: Oh no!!, Again a new error.
Caused by: org.jetbrains.kotlin.gradle.tasks.CompilationErrorException: Compilation error. See log for more details
Step 5: Again, go to project explorer and click build.gradle(:app). There you will find under composeOptions -> kotlin compiler extension version kotlinCompilerExtensionVersion '1.3.2'.
composeOptions {
kotlinCompilerExtensionVersion '1.3.2'
}
Step 6: Here kotlinCompilerExtensionVersion version in my case is 1.3.2. Now, change this version to latest available kotlinCompilerExtensionVersion version, while writing this solution kotlinCompilerExtensionVersion version is 1.4.7 and sync project.
composeOptions {
kotlinCompilerExtensionVersion '1.4.7'
}
Step 7: Step 3: Re Run your app in your device or Emulator.
Volha!. Error Fix
Conclusion
In conclusion, fixing a “Duplicate class” error in a Jetpack Compose project involves identifying and resolving conflicts between dependencies that contain the same class. This can be done by removing one of the conflicting dependencies, excluding the conflicting class from one of the dependencies, or changing the versions of the conflicting dependencies. By taking these steps, you can resolve the issue and successfully build your Jetpack Compose project.
