我正在尝试迁移旧的IntelliJ项目以使用gradle.但是,在dx步骤期间,assembleDebug失败： @H_502_2@java.lang.IllegalArgumentException: already added: Lcom/google/inject/AbstractModule; at com.android.dx.dex.file.ClassDefsSection.add(ClassDefsSection.java:123) at com.android.dx.dex.file.DexFile.add(DexFile.java:163) at com.android.dx.command.dexer.Main.processClass(Main.java:490) at com.android.dx.command.dexer.Main.processFileBytes(Main.java:459) at com.android.dx.command.dexer.Main.access$400(Main.java:67) at com.android.dx.command.dexer.Main$1.processFileBytes(Main.java:398) at com.android.dx.cf.direct.ClassPathOpener.processArchive(ClassPathOpener.java:245) at com.android.dx.cf.direct.ClassPathOpener.processOne(ClassPathOpener.java:131) at com.android.dx.cf.direct.ClassPathOpener.process(ClassPathOpener.java:109) at com.android.dx.command.dexer.Main.processOne(Main.java:422) at com.android.dx.command.dexer.Main.processAllFiles(Main.java:333) at com.android.dx.command.dexer.Main.run(Main.java:209) at com.android.dx.command.dexer.Main.main(Main.java:174) at com.android.dx.command.Main.main(Main.java:91)

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：

@H_502_2@include 'MainApp' include 'library' include 'common-library'

根目录中的build.gradle：

@H_502_2@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：

@H_502_2@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：

@H_502_2@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' }
