How to fix Gradle error in Android Studio?

The error message “Caused by: org.gradle.workers.internal.DefaultWorkerExecutor$WorkExecutionException: A failure occurred while executing” indicates that Gradle is having trouble checking for duplicate classes in your app. This can happen for a number of reasons, such as:

  • You have two or more dependencies that include the same class.
  • You are using a library that has been compiled with a different version of Java than your app.
  • Your app is using reflection to access classes that are not explicitly included in your dependencies.

To debug this error, you can try the following steps:

  1. Check your dependencies for duplicate classes. You can use the Gradle Dependency Graph task (gradlew dependencies) to see a list of all of the dependencies that your app is using. If you see any classes that are listed multiple times, you will need to remove one of the dependencies.
  2. Make sure that your dependencies are compiled with the same version of Java as your app. You can check the compileSdkVersion setting in your app’s build.gradle file to see what version of Java your app is using. Then, make sure that all of your dependencies are also compiled with the same version of Java.
  3. If your app is using reflection, make sure that you are explicitly including all of the classes that you are accessing. You can do this by adding them to your app’s build.gradle file as dependencies.

If you are still having trouble debugging this error, you can try searching for help online or posting a question on Stack Overflow.

Here are some additional tips for debugging Gradle errors:

  • Make sure that you are using the latest version of Gradle. You can check the Gradle website for the latest version.
  • Clean your project before building it. You can do this by running the gradlew clean task.
  • Enable verbose Gradle output. You can do this by setting the GRADLE_OPTS environment variable to -verbose. This will give you more information about the build process, which can be helpful for debugging errors.
  • Use the Gradle Profiler. The Gradle Profiler can help you identify bottlenecks and performance issues in your build process.
