android - Gradle 多项目构建因 UnsupportedNotationException 而失败

Question

我正在尝试将 Eclipse/ANT 项目转换为 Android Studio 和 Gradle。我已经从 Eclipse 导出了 gradle 构建脚本，将一些第三方库翻译成 Maven 中央存储库引用，并将项目导入到 Android Studio。

我正在尝试设置多项目构建。我目前的结构是:

Root     
  -- AndroidLibraryProject    
    -- build.gradle
  -- AndroidAppProject
    -- build.gradle
    -- settings.gradle

相关构建文件内容如下:

AndroidLibraryProject/build.gradle

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.6.+'
    }
}
apply plugin: 'android-library'

repositories {
    mavenCentral()
    maven {
        url "https://github.com/dahlgren/vpi-aar/raw/master"
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:18.0.+'
    compile 'com.viewpagerindicator:library:2.4.2-SNAPSHOT'
    compile files('libs/crashlytics.jar')
    compile files('libs/gson-2.0.jar')
}

android {
    compileSdkVersion "Google Inc.:Google APIs:19"
    buildToolsVersion "18.1.1"

    defaultConfig {
        minSdkVersion 10
        targetSdkVersion 17
    }
    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }

        instrumentTest.setRoot('tests')
    }
}

AndroidAppProject/build.gradle

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.6.+'
    }
}

evaluationDependsOn(':AndroidLibraryProject')

apply plugin: 'android'

dependencies {
    compile project()
}

android {
    compileSdkVersion 18
    buildToolsVersion "19"

    defaultConfig {
        minSdkVersion 10
        targetSdkVersion 18
    }
    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src2']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }
    }
}

AndroidAppProject/settings.gradle

include ':AndroidLibraryProject'
project(':AndroidLibraryProject').projectDir = new File(settingsDir, '../AndroidLibraryProject')

LibraryProject 可以自行清理和构建。

如有任何指导，我们将不胜感激。我是不是把这个项目配置都弄错了？我什至不确定它与我的构建配置有什么关系。

将 settings.gradle 文件向上移动一级到根目录。然后你应该能够像这样指定它:

include ':AndroidLibraryProject', ':AndroidAppProject'

应用构建文件中的 evaluationDependsOn 可能比您需要的更复杂。让应用程序依赖于库项目的正常方法是:

dependencies {
    compile project(':AndroidLibraryProject')
}

目前 Android Studio 不支持在项目根目录 ( https://code.google.com/p/android/issues/detail?id=56367 ) 之外使用库或模块，我认为您的原始设置可能符合条件，因为它可能将包含 settings.gradle 的目录视为根。像我描述的那样设置的东西会更快乐。
