How to resolve Duplicate files copied in APK META-INF/rxjava.properties

问题:

I am using rxjava and rxvolley on my android aplication. When I try to run it I get this error

Execution failed for task ':testapp:transformResourcesWithMergeJavaResForDebug'. > com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META-INF/rxjava.properties             File1: C:\Users\Daniel\.gradle\caches\modules-2\files-2.1\io.reactivex\rxjava\1.1.0\748f0546d5c3c27f1aef07270ffea0c45f0c42a4\rxjava-1.1.0.jar             File2: C:\Users\Daniel\.gradle\caches\modules-2\files-2.1\io.reactivex.rxjava2\rxjava\2.0.3\d2f725668bd22e21170381b23f8fbdf72c69d886\rxjava-2.0.3.jar 

I have a exclude.gradle file like this

android { packagingOptions {     exclude 'META-INF/DEPENDENCIES.txt'     exclude 'META-INF/NOTICE'     exclude 'META-INF/NOTICE.txt'     exclude 'META-INF/LICENSE'     exclude 'META-INF/LICENSE.txt'     exclude 'META-INF/rxjava.properties'     exclude 'META-INF/rxjava.PROPERTIES'     exclude 'META-INF/RXJAVA.properties'     exclude 'META-INF/RXJAVA.PROPERTIES'     exclude 'META-INF/rxjava'     exclude 'META-INF/RXJAVA' }  lintOptions {     abortOnError false } } 

How can I fix this problem?

回答1:

I had the same issue. I guess it is an error with the compatibility of the libraries.
In my case I am using Retrofit2 but I assume that the issue is with the rx libraries

This is the build.gradle (module:app) I am using and in my case works.

compile 'com.squareup.retrofit2:retrofit:2.0.2' compile 'com.squareup.retrofit2:converter-gson:2.0.2' compile 'com.squareup.retrofit2:adapter-rxjava:2.0.2'  compile 'io.reactivex:rxandroid:1.1.0' //

I had the same problem. The way I fixed it is adding the packaginOptions in app gradle as described in Duplicated file rxjava.properties

android {      defaultConfig {     }     buildTypes {     }     packagingOptions{         exclude 'META-INF/rxjava.properties'     } }

I encountered the same issue and fixed it by putting below code in app/build.gradle file. Please note that you have to put '*' at the end of path to exclude all the files inside the folder. You will have to change the path of files to be excluded in the below code based on error description.

compileSdkVersion 25     buildToolsVersion "24.0.3"      packagingOptions {         exclude 'com/google/appengine/repackaged/org/apache/commons/codec/language/bm/*'         exclude 'com/google/appengine/repackaged/org/codehaus/jackson/impl/*'         exclude 'com/google/appengine/repackaged/org/apache/commons/codec/language/*'     }

I had this issue today and fixed this problem

compile 'com.squareup.retrofit2:retrofit:2.2.0' compile 'com.squareup.retrofit2:converter-gson:2.2.0' compile 'com.jakewharton.retrofit:retrofit2-rxjava2-adapter:1.0.0'  //RxJava dependencies compile 'io.reactivex.rxjava2:rxandroid:2.0.0' compile 'io.reactivex.rxjava2:rxjava:2.0.2' compile 'org.reactivestreams:reactive-streams:1.0.0' 

回答5:

I also have this problem ,I also used the same method as you ,but because I hava two module ,I only chang it in the module which dependency Rxjava,Finally I I fixed it is adding the packaginOptions in app gradle

packagingOptions {     exclude 'META-INF/rxjava.properties' }
