Error:Execution failed for task ':app:transfor

问题:

Good day. After updating google repository in AndroidStudio, I have an issue

> Error:Execution failed for task \':app:transformClassesWithJarMergingForDebug\'.
> com.android.build.transform.api.TransformException: java.util.zip.ZipException: duplicate entry:
> android/support/v7/cardview/BuildConfig.class

I\'m trying to exclude group android.support from play-services, it did not help. When I started my project on another PC I have:

> Error:Execution failed for task  \':app:transformClassesWithJarMergingForDebug\'.
> com.android.build.transform.api.TransformException: java.util.zip.ZipException: duplicate entry:
> android/support/annotation/AnimRes.class

my build.gradle:

apply plugin: \'com.android.application\'
apply plugin: \'com.android.databinding\'

android {
    compileSdkVersion 23
    buildToolsVersion \"23.0.1\"

    defaultConfig {

            proguardFiles getDefaultProguardFile(\'proguard-android.txt\'), \'proguard-rules.pro\'
        }
    }
}

回答1:

In terminal execute in root project folder:

./gradlew clean

It helped me.

回答2:

AndroidStudio Menu:

Build/Clean Project

Update old dependencies

回答3:

All the above not working for me.. Because I am using Facebook Ad dependency..

Incase If anybody using this dependency compile \'com.facebook.android:audience-network-sdk:4.16.0\'

Try this code instead of above

compile (\'com.facebook.android:audience-network-sdk:4.16.0\'){
exclude group: \'com.google.android.gms\'
}

回答4:

Open your system command prompt/terminal -> Go to your Project folder path (root project folder ) -> Execute following command : command :- gradlew clean or ./gradlew clean

Make sure that all your gradle dependencies are of same version. -> Example :- your appcompat and recyclerview dependencies should have same version.

-> Change your gradle dependencies to same version like :-

compile \'com.android.support:appcompat-v7:23.4.0\'
compile \'com.android.support:design:23.4.0\'
compile \'com.android.support:recyclerview-v7:23.4.0\'
compile \'com.android.support:cardview-v7:23.4.0\'

-> Rebuild your project and it will work fine.

回答5:

Use project root in terminal like this:-/Users/rajnish/Desktop/RankProjects/ProjectCloud

After that enter this command ./gradlew clean

It will work.

回答6:

There may be different reason for reported issue, few days back also face this issue \'duplicate jar\', after upgrading studio. From all stackoverflow I tried all the suggestion but nothing worked for me.

But this is for sure some duplicate jar is there, For me it was present in one library libs folder as well as project libs folder. So I removed from project libs folder as it was not required here. So be careful while updating the studio, and try to understand all the gradle error.

回答7:

I got this error because I did not have the correct line in my build.gradle. I am using the org.apache.http.legacy.jar library, which requires this:

android{
   useLibrary \'org.apache.http.legacy\'

   ...
}

So check that you have everything in your gradle file that is required.

回答8:

I resolved the issue by double checking the \"libs\" directory and removing redundant jars, even though those jars were not manually added in the dependencies.

回答9:

see if their duplicate jars or dependencies your adding remove it and your error will be gone: Eg: if you add android:supportv4 jar and also dependency you will get the error so remove the jar error will be gone

回答10:

I resolve this is by changing the version no of recyleview to recyclerview-v7:24.2.1. Please check your dependencies and use the proper version number.

回答11:

For me the issue was caused by com.google.android.exoplayer conflicting with com.facebook.android:audience-network-sdk.

I fixed the problem by excluding the exoplayer library from the audience-network-sdk :

compile (\'com.facebook.android:audience-network-sdk:4.24.0\') {
    exclude group: \'com.google.android.exoplayer\'
}
