Error: Program type already present when building project












0















I'm using an 'aar' library which I created.
In both, my project and the library, there is a dependency implementation of Conceal library (each from its own lib folder).



When I build the project after importing the library and using ProGuard obfuscation, I get this error message:



Error: Program type already present: com.facebook.crypto.cipher.NativeGCMCipher


How can I resolve this problem?

          this error say you are importing the dependency which already imported in project.



          solution :- remove or exclude this dependency



          ex:-



          compile ('com.github.ganfra:material-spinner:1.1.1'){
          exclude group: 'com.nineoldandroids'
          }

          • I understand that the dependency imported already, but when remove it from the library I can't build because its missing the library, and when I remove it from the project it can't import from the library. How can I exclude it from the library?

          • I'm implementing using a jar file: implementation files('libs/conceal_android.jar') implementation files('libs/libconceal.jar') should I write: implementation files('libs/libconceal.jar') {exclude group: 'com.facebook.crypto.cipher.NativeGCMCipher'}

          according to mavenCentral(), this is the package name (which could be used instead of .jar):



          // https://mvnrepository.com/artifact/com.facebook.conceal/conceal
          implementation "com.facebook.conceal:conceal:2.0.2"


          therefore the exclusion should look about like this:



          implementation( project(":libraryproject") ) {
          exclude group: "com.facebook.conceal"
          }

          • @Itay are you certain to have used the code as displayed? that syntax is correct. if you get any Gradle DSL method not found: 'exclude()', you might be missing the surrounding () brackets.

          To my understanding, the error means that I imported a dependency that already imported in the project (once in the project and once in the library).
          The suggested solutions of @Mayur Dabhi and @Martin Zeitler had the right approach, but unfortunately, I wasn't able to get the exclude command working.



          finally, with the help of @Martin Zeitler, I replaced:



          implementation files('libs/conceal_android.jar')
          implementation files('libs/libconceal.jar')


          with:



          implementation "com.facebook.conceal:conceal:2.0.2"


          meaning I removed the 'Conceal' jar files from the 'lib' folder and imported the dependency. After that, the error message disappeared and I managed to build the project.



          Thanks for anyone who tried to help :)

            Add this to your gradle.properties file:




            android.useAndroidX=true
            android.enableJetifier=true



            It will auto resolve the android.support/androidx conflicts that you may have in the dependencies in your libraries.

            • @Itay are you certain to have used the code as displayed? that syntax is correct. if you get any Gradle DSL method not found: 'exclude()', you might be missing the surrounding () brackets.

            To my understanding, the error means that I imported a dependency that already imported in the project (once in the project and once in the library).
            The suggested solutions of @Mayur Dabhi and @Martin Zeitler had the right approach, but unfortunately, I wasn't able to get the exclude command working.



            finally, with the help of @Martin Zeitler, I replaced:



            implementation files('libs/conceal_android.jar')
            implementation files('libs/libconceal.jar')


            with:



            implementation "com.facebook.conceal:conceal:2.0.2"


            meaning I removed the 'Conceal' jar files from the 'lib' folder and imported the dependency. After that, the error message disappeared and I managed to build the project.



            Thanks for anyone who tried to help :)
