Possible Causes of the Error

After analyzing the error message, we’ve identified a few potential causes that might be triggering this issue:

  • Incompatible versions of KSP and Hilt: One of the most common reasons for this error is the mismatch between the versions of KSP and Hilt. Make sure you’re using compatible versions of both libraries.
  • Corrupted Gradle cache: Sometimes, the Gradle cache can become corrupted, leading to issues like this. Try deleting the Gradle cache and rebuilding your project.
  • Conflicting dependencies: If you have other dependencies in your project that are conflicting with KSP and Hilt, it might cause this error. Check your dependencies and remove any unnecessary ones.
  • Misconfigured build.gradle file: A misconfigured build.gradle file can also cause issues like this. Double-check your build.gradle file and make sure it’s correctly configured.

Solution 1: Check the Versions of KSP and Hilt

As mentioned earlier, incompatible versions of KSP and Hilt can cause this error. To resolve this, make sure you’re using compatible versions of both libraries. Here’s how:

  1. Open your build.gradle file and check the versions of KSP and Hilt.
  2. Verify that the versions are compatible. You can check the official documentation for the compatible versions.
  3. If you’re using an incompatible version, update to a compatible one and rebuild your project.

For example, if you’re using KSP 1.6.10, you should use Hilt 2.38.1 or higher.


dependencies {
    implementation 'com.google.devtools.ksp:symbol-processing-api:1.6.10'
    implementation 'com.google.dagger:hilt-android:2.38.1'
}

Solution 2: Delete the Gradle Cache

Deleting the Gradle cache can resolve issues like this. Here’s how:

  1. Open your terminal or command prompt and navigate to your project directory.
  2. Run the following command to delete the Gradle cache: ./gradlew --stop (for Linux/macOS) or gradlew --stop (for Windows)
  3. Wait for the command to complete.
  4. Rerun your build command to rebuild your project.

This will delete the Gradle cache and rebuild your project, which might resolve the issue.

Solution 3: Check for Conflicting Dependencies

Conflicting dependencies can also cause issues like this. To resolve this:

  1. Open your build.gradle file and review your dependencies.
  2. Check for any dependencies that might be conflicting with KSP and Hilt.
  3. Remove any unnecessary dependencies that might be causing the conflict.
  4. Rerun your build command to rebuild your project.

For example, if you’re using another dependency injection framework like Dagger, it might be conflicting with Hilt. Remove the conflicting dependency and try rebuilding your project.

Solution 4: Check Your build.gradle File

A misconfigured build.gradle
