This error is caused by adding a support library instead of AndroidX  Make sure you use which one  for AndroidX  dependencies       def multidex version    quot 2 0 1 quot      implementation  androidx multidex multidex  multidex version     If you aren t using AndroidX  dependencies     implementation  com android support multidex 1 0 3     Also in manifest use the application class name instead of  quot android support multidex MultiDexApplication quot  in the application tag my application class name is G   the mistake   lt application             android name  quot android support multidex MultiDexApplication quot   gt               lt  application gt   right   lt application             android name  quot  G quot   gt               lt  application gt

I had a similar problem  i was getting the error message -  Error Execution failed for task   app transformResourcesWithMergeJavaResForDebug    More than one file was found with OS independent path  javax annotation WillCloseWhenClosed java    As stated in some of the answers above  using the below code works    packagingOptions          exclude  allclasses-frame html           But i was getting this error for 20 different files  so after excluding 20 files  i stopped and tried to find a decent solution  I had also encountered the   Unable to execute dex  Multiple dex files  error    I finally managed to solve this   Firstly  as in my case WillCloseWhenClosed java was the duplicate file   in android studio you have an option of  search everywhere   Write and search for the file there  There i found multiple instances of this file  So i clicked on both instances and saw their location by right clicking on the file and seeing its location when they opened in android studio    Secondly  I figured out that i had some dependencies in gradle file  I was using the below code  dependencies       compile  com google api-client google-api-client 1 23 0      and also i had their same zip packages in the location   Users user AndroidStudioProjects git appname app libs google-http-client-1 23    So this was redundant and thats why gradle is finding 2 files  So i deleted my zip packages and it solved the errors for me  Be carefull while doing this  You have to figure out which is the correct file or package to be deleted   Thirdly  gradle also makes a zip of these bug files in this location  At least for me it made  - C  Program Files Android Android Studio gradle m2repository com google code findbugs jsr305 1 3 9 jsr305-1 3 9 jar   so i went and deleted the jsr305-1 3 9 jar file from here also   If you are still confused  just go the  search everywhere  in android studio  find instances of your file there and you would have to delete one of them  Take your time and figure out which one

I has encountered the same error  and I found that it resulted from different modules contained the same classes from different packages   e g  One used androidx package  and the other used pre-androidx  I solved it by migrating the pre-androidx module to androidx using built-in feature of Android Studio   Refactor --  Migrate to Androidx     without excluding anything     For your situation  you may check if you have any dependency mismatches among modules

I have read all the answers related to getting this message in Android Studio      More than one file was found with OS independent path    META-INF LICENSE    but in this case excluding classes is no neccessary  we only need to exclude  META-INF DEPENDENCIES   this can be done inside the  app build gradle   android                      packagingOptions           exclude  META-INF DEPENDENCIES

In my case it was enough to exclude only path  META-INF DEPENDENCIES  on yourProject app build gradle inside android      Here it is  packagingOptions       exclude  META-INF DEPENDENCIES      And then do Clean Project and Rebuild Project

I my app  I was adding the jar dependencies like this   implementation files  libs json-simple-1 1 1 jar     But I realised that they were already added because of the following first line in dependencies   implementation fileTree include      jar    dir   libs     This line adds all the jars in lib folder to app dependency   Hence after removing the extra dependency implementation files  libs json-simple-1 1 1 jar     it is working fine

Basically when gradle puts together the apk file  it copies content from all the compile dependencies  It is intelligent enough to see that there is a duplicate file  coming from two different jar files  This could be any file like a txt or META-INF DEPENDENCIES  It might be best to exclude these files using the below  in case the file is present there only for informational purposes   android      packagingOptions          exclude  META-INF DEPENDENCIES            Or if in case  the file is a mandatory file like a class file  that has been duplicated across two jar dependencies that are related to each other  it is best to find alternatives to these jars  in the way of a more compatible version

For me  I was using someone s project and I was having issue compiling the lib  The solution to add packagingOptions didn t helped because it would prevent compiling latest  so file of armeabi-v7a and will copy the  so file from jniLibs to the built APK file I deleted the jniLibs folder from  app src main and it solved the problem

I faced this issue  first with some native libraries   so files  and then with java kotlin files  Turned out I was including a library from source as well as referencing artifactory through a transitive dependency  Check your dependency tree to see if there are any redundant entries  Use   gradlew  app dependencies to get the dependency tree  Replace  app  with your module name if the main module name is different

In many of the answers on SO on this problem it has been suggested to add exclude  META-INF DEPENDENCIES  and some other excludes  However none of these worked for me  In my case scenario was like this   I had added this in dependancies   implementation  androidx annotation annotation 1 1 0    And also I had added this in gradle properties   android useAndroidX true   Both of these I had added  because I was getting build error  cannot find symbol class Nullable  and it was suggested as solution to this on some of answers like here  However  eventually I landed up in getting error     More than one file was found with OS independent path  androidsupportmultidexversion txt    No exclude was working for me  Finally I just removed those added lines above just out of suspecion  Solved  cannot find symbol class Nullable  in some alternative way  and finally I got rid of this  More than one file was found with OS     build error  I wasted hours of mine  But finally got rid of it

The solutions here didn t help me  but this link did   If you have a library that s adding some android  so files    like libassmidi so or libgnustl shared so    you have to tell gradle to pick just one when packaging  otherwise you ll get the conflict   android     packagingOptions       pickFirst  lib armeabi-v7a libassmidi so      pickFirst  lib x86 libassmidi so          I was having this issue when using a React Native app as a library in an Android project  Hope it helps

I have faced a similar issue working in a multiple modules app environment      Error  Execution failed for task     app transformResourcesWithMergeJavaResForDebug   More than one file   was found with OS independent path  META-INF AL2 0    This issue was being reported by several of these modules of mine and none of the above solutions were fixing it  Turns out  I was using version Coroutines 1 3 6 which seemed to be embedding META-INF AL2 0 which was already embedded by another of the libraries I was using  To fix it  I have added the following code snippet to the build gradle of the module that was failing   configurations all       resolutionStrategy           exclude group   org jetbrains kotlinx   module   kotlinx-coroutines-debug             Given that it was happening on multiple modules  I have moved that resolutionStrategy code to my project level build gradle  Everything worked after that

Had similar message     Error Execution failed for task   app transformResourcesWithMergeJavaResForDebug     More than one file was found with OS independent path  constant-values html    To resolve it  I had to enable packages view 1  in Android Studio  then browse through the tree to libraries  and locate the duplicates 2   Then  ctrl alt f12  or RMB menu  3  - and found libraries which caused the issue   Made list of files inside those libs which caused the issues  and wrote them to app s build gradle file inside android section  Other option is to deal with the library  containing duplicate files  packagingOptions       exclude  allclasses-frame html      exclude  allclasses-noframe html       lt    gt
