在 Android Studio 0.8.2 上，我正在尝试使用 Spring 创建一个与 Twitter 集成的应用程序。有无数的构建问题，直到我创建了一个空白活动，我只是使用测试我的 Gradle 构建。

每次我尝试连接到 spring-social-twitter 时，构建都会失败。如果我注释掉 Twitter 依赖项，应用程序就会编译。我很确定这与应用程序本身无关，因为我正在一个空白应用程序上对其进行测试。

我究竟做错了什么？

我的 build.gradle 文件：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 20
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "com.example.testapplication"
        minSdkVersion 8
        targetSdkVersion 20
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    packagingOptions {
        exclude 'META-INF/ASL2.0'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/notice.txt'
    }
}

configurations.compile {
    exclude module: 'spring-core'
    exclude module: 'spring-web'
    exclude module: 'commons-logging'
}

    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:20.+'

    compile 'org.springframework.social:spring-social-twitter:1.+' // <- The offending line
    compile 'com.fasterxml.jackson.core:jackson-databind:2.3.2'
}

我可以让你走得更远，但你可能会陷入下一个问题。

如果我加载您的构建文件（并重现您的构建错误），当我进入 IDE 并要求它带我去BeansException上课时，我会得到：

的屏幕截图

您可以看到它BeansException是在两个不同的地方定义的，这在 Android 版本中是不允许的，因此您会看到错误。您需要设置您的构建，以便在一个地方定义每个类。

做更多的调查，你可以使用这个命令来查看你的依赖树。从应用程序的模块目录中，运行以下命令：

../gradlew dependencies

输出的相关部分在这里：

从这里我们可以看到它org.springframework.social:spring-social-twitter:1.+最终包含org.springframework:spring-beans:4.0.2.RELEASE了它的传递依赖（你发现它是因为你将它隔离为导致构建问题的行），但这意味着如果它已经被捆绑到 spring-android-core jar 中，它是多余的。我没有看到 spring-android-core 对 spring-beans 的另一个依赖；也许该类只是打包到 jar 中，甚至不是依赖项。

无论如何，您可以在依赖项中使用此语法来告诉 Gradle 不要选择传递依赖项：

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:20.+'
    compile 'org.springframework.android:spring-android-rest-template:1.+'
    compile 'org.springframework.android:spring-android-auth:1.+'
    compile 'org.springframework.android:spring-android-core:1.+'
    compile 'org.springframework.security:spring-security-crypto:3.+'
    compile 'org.springframework.social:spring-social-core:1.+'
    compile('org.springframework.social:spring-social-twitter:1.+') {
        exclude module: 'spring-beans'
    }
    compile 'com.fasterxml.jackson.core:jackson-databind:2.3.2'
}

如果我这样做，那么不再有 dex 多文件定义类错误。但是，我现在得到了这个类似但不同的重复文件错误，我可以稍微思考一下，但我不确定是否可以在不编写实例化 Spring 的测试应用程序的情况下修复它，这超出了我的范围我会做一个这样的答案；）

:app:packageDebug

You can ignore those files in your build.gradle:
    android {
      packagingOptions {
        exclude 'META-INF/spring.schemas'
      }
    }

这意味着META-INF/spring.schemas从两个不同的地方包含两个文件，这也是不允许的。但是，在这里你没有告诉 dex 忽略其中一个的灵活性；您可以通过以下方式告诉它忽略所有这些：

android {
  packagingOptions {
    exclude 'META-INF/spring.schemas'
  }
}

在您的构建文件中。我有一种感觉，Spring 需要该模式文件（虽然是哪个？？？？），所以如果你这样做，你的应用程序可能仍然无法工作。尝试并尝试使用它，如果您仍然遇到问题，您可以发布另一个问题并获得更专业的帮助。

我不确定这个问题的根源是什么。Spring 库中是否存在多个模式文件的打包错误？或者您希望解决这个问题？还是其他构建系统只是做正确的事？我不确定。

好的，这远不是人们所说的令人满意的解决方案，但是事情可以编译，所以我很“高兴”。

无论问题的根源是什么，它似乎都特定于 spring-social-twitter 版本 1.1.0。我将 build.gradle 行更改为：

compile 'org.springframework.social:spring-social-twitter:1.0.5.RELEASE'

而不是我以前的 ...spring-social-twitter:1.+' 现在编译得很好。尚未测试工作方面，但这将是一组完全不同的问题。

我向你保证，找到这个的方法与实际的“解决方案”一样荒谬。
