无法将依赖项添加到Android Project [英] Can't add dependency to Android Project

问题描述

我正在尝试基于gradle将'commons-validator'添加到我在Android Studio中的android项目中.我根据需要使用UrlValidator.

I'm trying to add 'commons-validator' to my android project in Android Studio based on gradle. I use UrlValidator for my needs.

因此，我在应用程序模块的build.gradle中添加了一个依赖项:

So I add a dependency in build.gradle of an app module:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:23.0.1'
    compile 'commons-validator:commons-validator:1.4.1' // this one
}

然后在应用程序标签中将using-library应用于AndroidManifest:

And uses-library to the AndroidManifest in application tag:

 <uses-library android:name="org.apache.commons.validator.routines.UrlValidator"
        android:required="true"/>

但是添加后，我的项目无法运行.

But after adding it my project fails to Run.

错误:任务':app:dexDebug'执行失败. com.android.ide.common.process.ProcessException:org.gradle.process.internal.ExecException:处理'command'/Library/Java/JavaVirtualMachines/jdk1.8.0_40.jdk/Contents/Home/bin/java''完成退出值为2的非零值

Error:Execution failed for task ':app:dexDebug'. com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/Library/Java/JavaVirtualMachines/jdk1.8.0_40.jdk/Contents/Home/bin/java'' finished with non-zero exit value 2

我也得到

警告:依赖项commons-logging:commons-logging:1.2在调试时会被忽略，因为它可能与Android提供的内部版本冲突. 如有问题，请用jarjar重新包装以更改类包

Warning:Dependency commons-logging:commons-logging:1.2 is ignored for debug as it may be conflicting with the internal version provided by Android. In case of problem, please repackage it with jarjar to change the class packages

4次:两次用于调试，两次用于发布.

4 times: two for debug and two for release.

推荐答案

我认为问题是传递依赖.研究了SO的一些线程之后，我在控制台中写了:

I think the problem were transitive dependencies. After researching some SO's threads I wrote in my console:

cd app/ #to enter app module folder
../gradlew dependencies

这给了我以下输出:

_debugCompile - ## Internal use, do not manually configure ##
+--- commons-validator:commons-validator:1.4.1
|    +--- commons-beanutils:commons-beanutils:1.8.3
|    |    \--- commons-logging:commons-logging:1.1.1 -> 1.2
|    +--- commons-digester:commons-digester:1.8.1
|    +--- commons-logging:commons-logging:1.2
|    \--- commons-collections:commons-collections:3.2.1

因此我将其添加到build.gradle:

So I added this to build.gradle:

compile('commons-validator:commons-validator:1.4.1'){
        exclude group: 'commons-logging'
        exclude group: 'commons-collections'
        exclude group: 'commons-digester'
        exclude group: 'commons-beanutils'
}

也有人告诉将multiDexEnabled true添加到defaultConfig部分，但是在我尝试不使用它的情况下，该功能对我来说是有效的.

Also some people told to add multiDexEnabled true to defaultConfig part but as I tried it works without it for me.

正如@Brucelet所说-从清单中删除了<uses-library>标签.

As @Brucelet said - removed <uses-library> tag from the manifest.

尽管gradle输出给出了许多AGPBI消息，但它可以正常运行并正常工作:

It runs and works correctly, although gradle output gives a lot of some AGPBI messages:
