你忘了应用Gradle插件了吗？但我应用了插件

Question

public final class MyApplication extends android. app.Application {
             ^
  Expected @HiltAndroidApp to have a value. Did you forget to apply the Gradle Plugin? (dagger.hilt.android.plugin)
  See https://dagger.dev/hilt/gradle-setup.html
  [Hilt] Processing did not complete. See the error above for details.

package com.example.hilt;

import android.app.Application;
import dagger.hilt.android.HiltAndroidApp;
import kotlin.reflect.KClass;

@kotlin.Metadata(mv = {1, 5, 1}, k = 1, d1 = {"\u0000\f\n\u0002\u0018\u0002\n\u0002\u0018\u0002\n\u0002\b\u0002\b\u0007\u0018\u00002\u00020\u0001B\u0005\u00a2\u0006\u0002\u0010\u0002\u00a8\u0006\u0003"}, d2 = {"Lcom/example/hilt/MyApplication;", "Landroid/app/Application;", "()V", "app_debug"})
@dagger.hilt.android.HiltAndroidApp
public final class MyApplication extends android.app.Application {
    
    public MyApplication() {
        super();
    }
}

// Top-level build file where you can add configuration options common to all sub-projects/modules.

allprojects {

        mavenCentral()

}

kapt {
    correctErrorTypes true
}

正如你所看到的，我做的每件事都是正确的，但它仍然给我带来了错误。我在另一台计算机上测试了我的代码，它起作用了！我甚至从我的电脑上删除了android studio，Gradle和SDK manager并重新安装它们，但它仍然给我错误。我该怎么修好它？

Answer 1

我终于找到了解决办法。在这里，您可以看到一个与支持Kotlin的插件1.5.20有关的问题，正如它解释的那样，这是Kotlin的插件的bug，而不是匕首柄的！

解决方案很简单，您必须将此代码添加到您的构建中。Gradle应用程序模块：

kapt {
    javacOptions {
        option("-Adagger.hilt.android.internal.disableAndroidSuperclassValidation=true")
    }
}
