Java 运行应用程序时渐变生成警告，无法运行应用程序

我对android非常陌生，无法理解此错误。同步gradle文件时，android studio将毫无错误地退出，但当我尝试构建并运行应用程序时，它会发出两个警告，如下所示：

Information:Gradle tasks [:app:generateDebugSources, :app:generateDebugAndroidTestSources]

Warning:Dependency org.apache.httpcomponents:httpclient:4.0.1 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

我的gradle文件如下：

apply plugin: 'com.android.application'

我尝试了在stackoverflow上能找到的一切，但它仍然显示错误。找不到任何正确的答案。请提出解决方案。由于这个原因，我被困在我的项目中。谢谢

您可以尝试删除该行：

编译文件树（dir:'libs'，include:['*.jar']）

即使这个问题已经很老了，它仍然没有解决，我花了一段时间在类似的配置中苦苦寻找原因

您排除了库中的重复导入，但导入了两次Google API

排除零件需要在中

compile('com.google.api-client:google-api-client:1.18.0-rc') {
    // Exclude artifacts that the Android SDK/Runtime provides.
    exclude group: 'xpp3', module: 'shared'
    exclude group: 'org.apache.httpcomponents', module: 'httpclient'
    exclude group: 'junit', module: 'junit'
    exclude group: 'com.google.android', module: 'android'
}

在您的示例中，您再次通过以下方式包含API：

compile([group: 'com.google.api-client', name: 'google-api-client-android', version: '1.20.0'])

没有导致重复导入的排除部分。

在我的情况下，我不得不这样排除两次。。我不认为这太复杂，但可能会让人困惑。我认为最好解决这些警告，因为它们可能会以奇怪的形式回来

compile ('com.google.apis:google-api-services-urlshortener:v1-rev47-1.22.0'){
    exclude module: 'httpclient' //by artifact name
    exclude group: 'org.apache.httpcomponents' //by group
    exclude group: 'org.apache.httpcomponents', module: 'httpclient' //by both name and group
}

compile ('com.google.api-client:google-api-client-android:1.21.0') {
    exclude module: 'httpclient' //by artifact name
    exclude group: 'org.apache.httpcomponents' //by group
    exclude group: 'org.apache.httpcomponents', module: 'httpclient' //by both name and group
}

这些是警告，不是错误。@JaredBurrows，但由于它的存在，它无法编译，我也找不到任何解决方案。您添加的上一个依赖项是什么导致它停止工作的？@JaredBurrows

编译文件（'libs/fresh_api-v1-1.20.0-SNAPSHOT.jar'）

？？这就是我正在导入的云端点api。有什么建议吗？我甚至不知道图书馆是什么。您应该尝试只使用渐变依赖项。
