总结，解决报错Inconsistent JVM-target compatibility detected for tasks ‘compileDebugJavaWithJavac’ (1.8) and ‘compileDebugKotlin’ (17).的方法是：

步骤一：根目录\app\中的build.gradle中添加

android {
    
    
    compileOptions {
    
    
        sourceCompatibility JavaVersion.VERSION_17
        targetCompatibility JavaVersion.VERSION_17
    }

    kotlinOptions {
    
     jvmTarget =17 }
}

步骤二：根目录中的build.gradle中添加

allprojects {
    
    
    tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).configureEach {
    
    
        kotlinOptions.jvmTarget = "17"
    }

    tasks.withType(org.jetbrains.kotlin.gradle.tasks.KaptGenerateStubs).configureEach {
    
    
        kotlinOptions.jvmTarget = "17"
    }
}
