使用时，摇篮上编译命令行的Andr​​oid库项目不能导入另一个库项目的R舱 [英] Android Library project can't import R class of another library project when using gradle to compile on command line

问题描述

我有这样的结构，我的Andr​​oid项目：

I have this structure for my android project:

ProjectDir  
settings.gradle  
MyApp(depends on LibraryA and LibraryB)  
-->build.gradle  
-->All the other android code  
LibraryA  (depends on LibraryB)  
-->build.gradle  
-->All the other android code  
LibraryB (Has lots of resources that are used in LibraryA and MyApp)  
-->build.gradle  
-->All the other android code  

我可以编译Android应用程序就好了使用Eclipse和Android的工作室。 LibraryA的进口LibraryB的R档做进口com.LibraryB.R; 我还利用 com.LibraryB.R.layout的。 ... 键入code参考只要我在IDE的东西都很好。

I can compile the android app just fine using both eclipse and Android Studio. LibraryA imports the R file of LibraryB by doing " import com.LibraryB.R;" I also make use of com.LibraryB.R.layout.... type references in code and as long as I'm in the IDE things are fine.

我想获得的东西来构建我们的CI服务器的命令行，我已经试过Ant和摇篮，我最终得到了相同的生成错误只。

I am trying to get things to build from the command line for our CI server and I have tried both ant and gradle and I end up getting the same build error in each.

LibraryA/example.java:10:error:cannot find symbol import com.LibraryB.R

我甚至去发布LibraryB作为本地AAR文件，并用它来建立LibraryA的程度

I have even gone to the extent of publishing LibraryB as a local aar file and using it to build LibraryA

LibraryB build.gradle

LibraryB build.gradle

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

group = 'com.libraryb'
version = '1.0'

apply plugin: 'android-library'
apply plugin: 'maven'

uploadArchives {
        repositories {
                mavenDeployer {
                        repository url: 'file://' + new File(System.getProperty('user.home'), '.m2/repository').absolutePath
                }
        }
}

task install(dependsOn: uploadArchives)

repositories {
    mavenLocal()
    mavenCentral()
}

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

android {
    compileSdkVersion 18
    buildToolsVersion "18.0.1"

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

LibraryA的build.gradle

LibraryA build.gradle

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

repositories {
    mavenLocal()
    mavenCentral()
}

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    compile 'com.libraryb:LibraryB:1.0'
}

android {
    compileSdkVersion 17
    buildToolsVersion "18.0.1"

    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')
    }
}

MyApp的build.gradle

MyApp build.gradle

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

group = 'com.myapp'
version = '1.0'

apply plugin: 'android-library'
apply plugin: 'maven'

uploadArchives {
        repositories {
                mavenDeployer {
                        repository url: 'file://' + new File(System.getProperty('user.home'), '.m2/repository').absolutePath
                }
        }
}

task install(dependsOn: uploadArchives)

repositories {
mavenLocal()
mavenCentral()
}

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

android {
    compileSdkVersion 18
    buildToolsVersion "18.0.1"

    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')
    }
}

settings.gradle

settings.gradle

include ':MyApp'
include ':LibraryA'  

我需要能够从其他库项目和主要的应用程序访问LibraryB的资源。我似乎无法找出什么我做错了。任何帮助将是巨大的。据透露，从Eclipse中使用生成的摇篮剧本给了同样的问题。

I need to be able to access the resources of LibraryB from other library projects and the main app. I can't seem to figure out what I'm doing wrong. Any help would be great. Fyi, using the generated gradle scripts from eclipse give the same issue.

推荐答案

您好：我有同样的问题，我的Andr​​oid库项目，使用另一个库（actionBarSherlock）。它不能解决进口com.actionbarsherlock.R; 当我在gradle.build改了行：  应用插件：机器人库 至：  应用插件：'机器人' 那么顺利。

Hello I had same problem, my android library project, uses another library (actionBarSherlock). It can't resolve import com.actionbarsherlock.R; when I changed the line in gradle.build: apply plugin: 'android-library' to: apply plugin: 'android' then it goes well.

但我需要它有这样一个图书馆。

But I needed it have like a library.

这里的解决方案： 解决办法是，从包括库R上的文件生成到库中。 而不是进口com.actionbarsherlock.R; 采用进口com.myprojectalsolibrary.R;

SOLUTION HERE: Solution Is that R files from included library are generated to your library. instead import com.actionbarsherlock.R; use import com.myprojectalsolibrary.R;
