android - 多项目 gradle 构建错误 : package does not exist

Question

我在使用 gradle 构建多项目时遇到了一些问题。我阅读了所有类似的问题，但没有任何帮助。我的项目结构如下:

App/
    settings.gradle
    app/
        build.gradle
    libraries/
        Core(git submodule)/
            Core/
                build.gradle
            libraries/
                ZBarLibrary/
                    build.gradle
            settings.gradle

应用程序/settings.gradle

include ':App', ':libraries:Core', ':libraries:ZBarLibrary'
project(':libraries:Core').projectDir = new File(settingsDir, 'libraries/Core/Core')
project(':libraries:ZBarLibrary').projectDir = new File(settingsDir, 'libraries/Core/libraries/ZBarLibrary')

应用/应用/build.gradle

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
}

android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 16
    }
}

dependencies {
    compile 'com.android.support:support-v4:18.0.0'
    compile project(':libraries:Core')
}

应用/库/核心/核心/build.gradle

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
}

dependencies {
    instrumentTestCompile "junit:junit:4.5+"
    compile project(':libraries:ZBarLibrary')
    compile fileTree(dir: 'libs', include: '*.jar')

}

android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 16
    }
}

App/libraries/Core/libraries/ZBarLibrary/build.gradle

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}
apply plugin: 'android-library'

repositories {
    mavenCentral()
}

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
}

android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 16
    }

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }
    }
}

App 目录中的命令“gradle build”产生错误:“package com ... does not exist”。这个包在应用程序模块中使用，但它位于 App/libraries/Core/Core/src/main/java 中。你能帮帮我吗？

Answer 1

您的应用模块的 build.gradle 应该包含(除其他外)

apply plugin: 'com.android.application'
dependencies {
    compile project(':my_library_module')
}

你的库模块的 build.gradle 文件应该包含

apply plugin: 'com.android.library'
