Question

我hava与retrolambda建立了一个App项目，用于JAVA 8的兼容性和对自己的android库的模块依赖，因为我在第二个应用程序中也使用了这个部分。问题是每次我使用gradle构建我的项目都没有错误和构建成功，但是当我想在我的设备上安装应用程序时，gradle就失败了

: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
        versionCode 1
        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（Module：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：

我对此感到疑惑，因为我的第二个具有相同设置的应用程序可以毫无问题地安装。为什么要在这个应用程序中发生崩溃？在我的java类中，编程没有问题，并且存在对android R类的导入，但是当安装gradle的构建移除了这个导入并且所有R将是红色直到几秒钟。 Android Studio自动导入右R

import my.package.app.R;

导入后，R不再是红色。

我已经测试过gradle clean并重建了几次（如其他问题所示）而没有解决问题......

感谢您的帮助：D

我最近有一个项目工作正常，直到今天发生同样的错误。

错误：任务＆＃39;：app：mergeDebugResources＆gt;执行失败1

我尝试了所有常用的修复程序，重新启动，重新同步，清理解决方案，使缓存无效并重新启动。直到......才有效：

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/已损坏项目的build.grade文件。将应用程序ID更改为旧项目中的内容。使用Gradle保存并重新同步。您现在可以使用您的应用程序！。
