Solving the Frustrating “Execution failed for task ‘:react-native-gradle-plugin:compileKotlin'” Error

Are you tired of seeing the cryptic error message “Execution failed for task ‘:react-native-gradle-plugin:compileKotlin'” every time you try to build or run your React Native project? You’re not alone! This pesky error has driven many developers to the brink of madness, but fear not, dear reader, for we’re about to dive into the solutions that will get you back to coding in no time.

Understanding the Error

The “Execution failed for task ‘:react-native-gradle-plugin:compileKotlin'” error typically occurs during the build process of a React Native project, specifically when Gradle is trying to compile the Kotlin code of the react-native-gradle-plugin. This plugin is responsible for integrating React Native with Gradle, allowing you to use native modules and frameworks in your project.

Why Does This Error Happen?

• Incompatible Plugin Version: The react-native-gradle-plugin version might be incompatible with your project’s Gradle or Kotlin versions.
• Missconfigured Gradle Setup: Issues with the Gradle configuration, such as incorrect plugins or dependencies, can cause the compilation to fail.
• Kotlin Version Inconsistencies: Using different Kotlin versions in your project and plugins can lead to compatibility issues.
• Plugin Issues: Bugs or conflicts within the react-native-gradle-plugin itself can cause the error.

Solutions to the “Execution failed for task ‘:react-native-gradle-plugin:compileKotlin'” Error

Now that we’ve explored the possible causes, let’s get to the good stuff – solving the problem!

Solution 1: Update the react-native-gradle-plugin Version

Try updating the react-native-gradle-plugin version to the latest one compatible with your project. Open your `build.gradle` file and update the plugin version:

buildscript {
  ext {
    // Try updating the plugin version to the latest one
    reactNativeGradlePluginVersion = "0.71.6"
  }
  ...
}

Solution 2: Check and Configure Gradle Settings

Verify that your Gradle setup is correct and configure it if necessary. Make sure you have the correct Gradle and Kotlin versions in your `build.gradle` file:

android {
  compileSdkVersion 29
  defaultConfig {
    minSdkVersion 21
    targetSdkVersion 29
    versionCode 1
    versionName "1.0"
  }
  buildToolsVersion "29.0.3"
}

kotlin {
  jvmToolchain {
    languageVersion.set(JavaLanguageVersion.of(11))
  }
}

Solution 3: Ensure Consistent Kotlin Versions

Verify that all Kotlin versions in your project and plugins are consistent. Check your `build.gradle` file for any inconsistencies:

kotlin {
  jvmToolchain {
    languageVersion.set(JavaLanguageVersion.of(11))
  }
}

dependencies {
  // Ensure the Kotlin version is consistent
  implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.6.10"
}

Solution 4: Clean and Rebuild Your Project

Sometimes, a simple clean and rebuild can resolve the issue. Run the following commands in your terminal:

rm -rf node_modules
rm -rf android/build
rm -rf ios/build
npx react-native run-android

Solution 5: Disable Kotlin Incremental Compilation

Disabling Kotlin incremental compilation can help resolve the issue. Add the following code to your `build.gradle` file:

android {
  ...
  compileOptions {
    incremental false
  }
}

Solution 6: Use the –stacktrace Option

Run the build command with the `–stacktrace` option to get more detailed error information:

npx react-native run-android --stacktrace

Solution 7: Check for Plugin Conflicts

If you’re using other plugins in your project, check for conflicts by disabling them one by one and see if the error persists. You might need to update or remove conflicting plugins.

Solution 8: Reinstall React Native and its Dependencies

As a last resort, try reinstalling React Native and its dependencies:

npm uninstall react-native
npm install react-native
