Question

今天，Android Studio刚刚发布3.0版。在我更新了所有依赖项之后，即使IDE没有在代码中显示任何错误，我也无法构建我的项目。（Gradle Sync很好。）

build.gradle（项目）

buildscript {
    ext.kotlin_version = "1.1.51"
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:3.0.0"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
        jcenter()
        google()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

build.gradle（App）

apply plugin: "com.android.application"
apply plugin: "kotlin-android"
apply plugin: "kotlin-android-extensions"
apply plugin: "kotlin-kapt"

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.2"

    defaultConfig {
        minSdkVersion 19
        targetSdkVersion 26
        versionCode 12
        versionName "1.1.2"
        vectorDrawables.useSupportLibrary = true
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

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

    flavorDimensions "build"

    productFlavors {
        UAT {
            resValue "string", "app_name", "UAT"
            dimension "build"
        }

        SIS {
            resValue "string", "app_name", "SIS"
            dimension "build"
        }

        PROD {
            resValue "string", "app_name", "PROD"
            dimension "build"
        }
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
        }
    }
}

dependencies {
    compile fileTree(dir: "libs", include: ["*.jar"])
    compile "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
    compile "org.jetbrains.kotlin:kotlin-reflect:$kotlin_version"
    compile "com.android.support:appcompat-v7:26.1.0"
    compile "com.android.support:support-v13:26.1.0"
    compile "com.android.support:design:26.1.0"
    compile "com.android.support.constraint:constraint-layout:1.0.2"
    // Skip
    testCompile "junit:junit:4.12"
    androidTestCompile "com.android.support.test.espresso:espresso-core:3.0.1"
    kapt "android.arch.persistence.room:compiler:1.0.0-rc1"
    kapt "com.google.dagger:dagger-compiler:2.11"
}

我已经尝试过api，实现和编译。

错误

e: C:\Users\user\AndroidStudioProjects\project\app\src\main\java\com\example\ContextExtension.kt: (47, 34): Unresolved reference: LOLLIPOP
e: C:\Users\user\AndroidStudioProjects\project\app\src\main\java\com\example\ContextExtension.kt: (104, 58): Unresolved reference: LOLLIPOP
e: C:\Users\user\AndroidStudioProjects\project\app\src\main\java\com\example\ContextExtension.kt: (173, 58): Unresolved reference: LOLLIPOP
...

但是在更新之前这条线很好，Android Studio不会将其突出显示为红色。

@RequiresApi(Build.VERSION_CODES.LOLLIPOP)

供您参考，错误显示在:app:compilePRODDebugKotlin。

编辑：我找到了原因。我误解了implementation并遗漏了exclude。添加回排除修复了问题。

使用Kotlin更新到Android Studio 3.0后构建错误
