我的项目分为两个子项目：主项目和图书馆项目.这两个项目都有Roboguice和Guice作为依赖项.

我尝试了Xav建议的解决方法,将支持库包含在in this answer中提到的多个项目中.鉴于roboguice / guice都是从maven中心获取的,因此可能甚至不需要解决方法.我创建了一个虚拟库项目,这是唯一依赖于roboguice / guice的项目.我做到了这一点,以便我的主项目和(真正的)图书馆项目都依赖于这个虚拟项目.但是,我得到了同样的错误.

怎么解决这个问题？

根目录中的settings.gradle：

include 'MainApp'
include 'library'
include 'common-library'

根目录中的build.gradle：

buildscript {
  repositories {
      mavenCentral()
  }
  dependencies {
      classpath 'com.android.tools.build:gradle:0.4.2'
  }
}

allprojects {
    version = '1.0'

    repositories {
        mavenCentral()
    }
}

apply plugin: 'android-reporting'

main项目中的build.gradle和真正的库项目：

apply plugin: 'android'

android {
    compileSdkVersion 15
    buildToolsVersion "17.0"
    sourceSets         {
      main {
           manifest.srcFile 'AndroidManifest.xml'
           java.srcDirs = ['src']
           res.srcDirs = ['res']
      }
    }
}

dependencies {
    compile project(':library') // only in main,not in real library
    compile project(':common-library')
}

虚拟库项目中的build.gradle：

apply plugin: 'android-library'

android {
    compileSdkVersion 15
    buildToolsVersion "17.0"
    sourceSets         {
      main {
           manifest.srcFile 'AndroidManifest.xml'
           java.srcDirs = ['src']
           res.srcDirs = ['res']
      }
    }
}

dependencies {
  compile 'org.roboguice:roboguice:2.0'
  compile 'com.google.inject:guice:3.0'
}
