安卓工作室 :app:compileDebugJavaWithJavac package R does not exist

标签 android android-studio gradle java-8 retrolambda

我已经设置了一个带有 retrolambda 的 App 项目，以实现 JAVA 8 兼容性和对自己的 android 库的模块依赖，因为我也在第二个 App 中使用了这部分。
问题是每次我用 gradle 构建我的项目时都没有错误并且构建成功，但是当我想在我的设备上安装应用程序时，gradle 失败了

:app:compileDebugJavaWithJavac with package R does not exist

这是我的gradle设置:

build.gradle(项目:“项目名称”)
buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.2'
        classpath 'me.tatarka:gradle-retrolambda:3.2.5'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

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

build.gradle(模块:app)
apply plugin: 'com.android.application'
apply plugin: 'me.tatarka.retrolambda'

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.0"

    defaultConfig {
        applicationId "my.package.app"
        minSdkVersion 19
        targetSdkVersion 24

        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

    packagingOptions {
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/LICENSE.txt'
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

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

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:design:24.0.0'
    compile 'org.florescu.android.rangeseekbar:rangeseekbar-library:0.3.0'
    compile project(path: ':myownmodule')
}

build.gradle(模块:myownmodule)
apply plugin: 'com.android.library'
apply plugin: 'me.tatarka.retrolambda'

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.0"

    defaultConfig {
        minSdkVersion 19
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    configurations {
        compile.exclude module: 'support-annotations'
    }

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

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:24.0.0'
    compile 'com.google.code.gson:gson:2.6.1'
    compile 'io.reactivex:rxandroid:1.1.0'
    compile 'io.reactivex:rxjava:1.1.3'
}

这是 gradle 控制台的输出:

我想知道这一点，因为我可以毫无问题地安装具有相同设置的第二个应用程序。
为什么 gradle 在这个应用程序中崩溃？在我的 java 类中，编程没有问题，并且存在对 android R 类的导入，但是在构建安装 gradle 时删除了这个导入，所有 R 将在几秒钟前变为红色。 Android Studio 自动导入正确的 R
import my.package.app.R;

并且在导入之后，R 不再是红色了。

我已经测试了 gradle clean 并重建了几次(如其他问题中所建议的那样)，但没有解决问题......

感谢您的帮助:D

最佳答案

我最近的一个项目运行良好，直到今天发生同样的错误。

错误:任务 ':app:mergeDebugResources > 1 的执行失败

我尝试了所有常见的修复，重新启动，重新同步，清理解决方案，使缓存无效并重新启动。什么都没起作用，直到...

修复:

对于每个类中的每个 build.gradle 文件，您将看起来像这样:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.1"

    defaultConfig {
        applicationId "com.ac130.memorygame"
        minSdkVersion 21
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:24.1.1'
}

现在，打开一个新项目。这个新项目应该调试得很好。从 Gradle Scripts 复制并粘贴新项目 build.gradle 并用该代码替换旧/损坏项目的 build.grade 文件。将应用程序 ID 更改为旧项目上的 ID。保存并与 Gradle 重新同步。您现在可以使用您的应用程序了!
