android - Expected @HiltAndroidApp to have a value. Did you forget to apply the Gradle Plugin?

Question

I have Google this problem, but the results are not work for me.

The detail as following.

    public final class App extends com.zhixin.wedeep.common.BaseApplication implements androidx.lifecycle.LifecycleOwner {
                 ^
     // Expected @HiltAndroidApp to have a value. Did you forget to apply the Gradle Plugin?

The App code.

@HiltAndroidApp
class App : BaseApplication(), LifecycleOwner {

    @Inject
    lateinit var service: EventService


    private val mLifecycleRegistry = LifecycleRegistry(this)

}

This module gradle file.

apply plugin: 'kotlin-kapt'
apply plugin: 'kotlin-allopen'
apply plugin: 'androidx.navigation.safeargs.kotlin'
apply plugin: 'dagger.hilt.android.plugin'

dependencies {
    implementation rootProject.ext.dependencies["hilt-android"]
    implementation rootProject.ext.dependencies["hilt-lifecycle-viewmodel"]
    kapt rootProject.ext.kapt["hilt-compiler"]
    kapt rootProject.ext.kapt["hilt-android-compiler"]
}

Who has ideas? Thanks!

I just hit this problem this morning. Do you have anything in your build.gradle that adds arguments to the annotationProcessOptions? For example:

  android {
        ...
        defaultConfig {
            ...
            javaCompileOptions {
                annotationProcessorOptions {
                    arguments = ["room.schemaLocation":
                                 "$projectDir/schemas".toString()]
                }
            }
        }
    }

If so, try changing from "arguments =" to "arguments +=", as just using equals overwrites anything set previously.
