java - 警告 :Dependency org. apache.httpcomponents :httpclient:4. 0.1 被忽略

Question

当我尝试将我的 libs2 文件夹中的任何 .jar 文件添加到我的 libs 文件夹时

我收到以下错误:

    Information:Gradle tasks [:app:assembleDebug]
    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

   .....
    :app:compileDebugNdk UP-TO-DATE
    :app:compileDebugSources
    :app:transformClassesWithDexForDebug

    Error:Execution failed for task ':app:transformClassesWithDexForDebug'.
    > com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.8.0_45\bin\java.exe'' finished with non-zero exit value 2

我知道 libs2 中的文件会导致错误，因为我会一个一个地添加它们并查看哪些会导致问题，基于这个人 suggestion .

我正在关注 tutorial这需要所有这些 .jar 文件，所以我不明白为什么我会收到这些错误，因为它们是必需的。

使用 Gradle 无需降级或寻找另一个 jar - 因为可以按组/模块过滤:

compile ('com.google.http-client:google-http-client-jackson2:1.21.0') {
    exclude group: 'org.apache.httpcomponents', module: 'httpclient'
}
