我的android项目依赖项httpclient和httpMime无法建立

Question

I'm use the dependencies by

compile 'org.apache.httpcomponents:httpmime:4.3.5'
compile 'org.apache.httpcomponents:httpclient-android:4.3.5'`

then build it there is error Error:Gradle: Execution failed for task ':XmppDemo:packageDebug'.

Duplicate files copied in APK META-INF/NOTICE File 1: E:\\develop\\gradle.gradle\\caches\\modules-2\\files-2.1\\org.apache.httpcomponents\\httpclient-android\\4.3.5\\82edcaec6c7b4599eaeaaf11167ceea41db42f33\\httpclient-android-4.3.5.jar File 2: E:\\develop\\gradle.gradle\\caches\\modules-2\\files-2.1\\org.apache.httpcomponents\\httpclient-android\\4.3.5\\82edcaec6c7b4599eaeaaf11167ceea41db42f33\\httpclient-android-4.3.5.jar

can you help me explain the reason. excuse me! i'm Chinese,my English is not good.

Answer 1

The packager is telling you that the file META-INF/NOTICE appears in more than one jar file (which creates a conflict) and therefore cannot be included. To solve that problem, add this section to your build.gradle (you might already have an android closure, in which case add just the packagingOptions part):

android {
  packagingOptions {
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/NOTICE.txt'
 }
}

Your particular problem is about the NOTICE file but I suspect that you might also run into problems with LICENSE and DEPENDENCIES .
