春季为Android构建包括Spring - 社会 - 微博时失败 [英] Spring for Android Build Failing when Including spring-social-twitter
本文介绍了春季为Android构建包括Spring - 社会 - 微博时失败的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
在Android的工作室0.8.2，我试图创建一个与Twitter使用Spring集成的应用。曾无数建的问题，直到我创建的，我只是用我的测试建立摇篮空白的活动。
我每次尝试连接到弹簧社会叽叽喳喳，构建失败。如果我注释掉Twitter的依赖，应用程序编译。我是pretty肯定这无关与应用程序本身，因为我上的一个空白的应用程序测试。
我在做什么错了？

解决方案
我可以帮你一起更远，但你可能会停留在一个问题。
如果我加载生成文件（和复制你的生成错误），当我去到IDE，并要求它带我到 BeansException 类，我得到这样的：
您可以看到 BeansException 在两个不同的地方，这是不是在允许的Android版本，因此错误，您现在看到的定义。您需要设置您的构建，使得每个类在一个地方定义。
做多一点侦探，你可以使用这个命令来查看你的依赖关系树。从应用程序的模块目录，运行以下命令：
../ gradlew依赖

从这里我们可以看出， org.springframework.social:spring-social-twitter:1 + 最终包括 org.springframework：春天-beans：4.0.2.RELEASE 通过其传递依赖（你发现了，因为你隔离这是导致你的构建问题就行），但是这意味着，如果它已经被捆绑成弹簧的Android -core罐子，它是多余的。我没有看到从春天的Android核心春豆另一个依赖;也许这类只是包装成罐子，甚至不是一个依赖。
在任何情况下，你可以使用这个语法在你的依赖，告诉摇篮不要拿起传递依赖：

在您的构建文件。我有一种感觉，春天需要一个架构文件（其中之一，尽管???），所以如果你这样做，你的应用程序可能仍然无法正常工作。试验和鞭打与它周围，如果你仍然有问题，不过，你可以张贴另一个问题，也许获得更多的专业帮助。
我不知道这个问题的根源是什么。它是在Spring库包装错误，有多个模式文件？或者，您希望解决这个问题？或者做其他的编译系统只是做对了吗？我不知道。
On Android Studio 0.8.2, I am trying to create an app that integrates with Twitter using Spring. Had innumerable build problems until I created a blank activity that I'm just using the test my Gradle build.
Every time I try to connect to spring-social-twitter, the build fails. If I comment out the Twitter dependency, the app compiles. I'm pretty sure this has nothing to do with the app itself, because I'm testing it on a blank app.
What am I doing wrong?

解决方案
I can get you farther along, but you may get stuck at the next problem.
If I load up your build file (and reproduce your build error), when I go into the IDE and ask it to take me to the BeansException class, I get this:
You can see that BeansException is defined in two different places, which isn't allowed in Android builds, thus the error you're seeing. You need to set up your build such that each class is defined in one place.
Doing a little more sleuthing, you can use this command to see your dependency tree. From your application's module directory, run this command:
../gradlew dependencies

From this we can see that org.springframework.social:spring-social-twitter:1.+ eventually includes org.springframework:spring-beans:4.0.2.RELEASE through its transitive dependencies (which you found out because you isolated this as the line causing your build problem), but that means if it's already being bundled into the spring-android-core jar, it's redundant. I don't see another dependency on spring-beans from spring-android-core; perhaps that class is just packaged into the jar and isn't even a dependency.
At any rate, you can use this syntax in your dependencies to tell Gradle to not pick up a transitive dependency:
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'
}
If I do this, then no more dex multiple-files-define-a-class error. However, I now get this similar but different duplicate-files error, which I can muse about a bit but I'm not sure if I could fix it without writing a test app that instantiates Spring, which is beyond the scope of what I'll do in a SO answer ;)
:app:packageDebug
Error: duplicate files during packaging of APK /Users/sbarta/AndroidStudioProjects/MyApplication/app/build/outputs/apk/app-debug-unaligned.apk

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

What this means is that there are two META-INF/spring.schemas files being included from two different places, which is also not permitted. However, you don't have the flexibility here of telling dex to ignore just one of them; you can tell it to ignore all of them via:
android {
packagingOptions {
exclude 'META-INF/spring.schemas'
}
}
in your build file. I have a feeling that Spring needs that schemas file (which one, though???), so if you do this, your app may still not work. Experiment and thrash around with it, and if you're still having problems, though, you can post another question and maybe get more specialized help.
I'm not sure what the root of this problem is. Is it a packaging error in the Spring libraries that there are multiple schema files? Or are you expected to resolve this? Or do other build systems just Do The Right Thing? I'm not sure.
