Encountering the error “A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptExecution” can be perplexing, especially when Android Studio does not provide clear directions on how to fix it. This guide aims to help you diagnose and resolve this issue effectively.

Understanding the Error

This error typically arises during the build process when there is an issue with annotation processing in Kotlin projects. It might be due to mismatched versions, missing annotations, or other underlying issues in your code or project configuration.

Steps to Diagnose and Resolve the Issue

1. Reveal the Complete Build Output

Sometimes, Android Studio’s UI might hide the root cause of the error. To uncover the real issue:

  • Select the root item in the build output list view.
  • Scroll through the terminal view to find the detailed error message.

2. Inspect Code for Errors

If the build output does not provide enough information, you can use Android Studio’s code inspection feature:

  • Go to Analyze > Inspect Code.
  • Choose to inspect the whole project and click OK.
  • Review the inspection results to identify and fix errors and warnings.

3. Update Dependencies

Outdated or incorrect dependencies can also cause this error. Ensure your dependencies are up-to-date. For example, if you are using Room, update your dependencies as follows:

implementation ""
annotationProcessor ""

4. Run Gradle with Stacktrace

Running your Gradle build with the --stacktrace option can provide more detailed information about the error:

./gradlew assembleDebug --stacktrace

5. Check for Specific Issues

Depending on your setup, there might be specific issues to look out for:

  • Ensure all Room entities and DAOs are correctly defined.
  • Update your JDK if you are using an outdated version.
  • Ensure there are no typos or missing annotations in your code.
