Conflict issue with com.google.protobuf:protobuf-java and firebase

Hello,

I am implementing app, but I met conflict library issue.

java.lang.RuntimeException: Duplicate class com.google.protobuf.AbstractMessageLite found in modules protobuf-java-3.9.1.jar (com.google.protobuf:protobuf-java:3.9.1) and protobuf-lite-3.0.1.jar (com.google.protobuf:protobuf-lite:3.0.1)

For using samsungblockchain sdk and transfer api, I should use protobuf. wihtout protobuf, I got the runtime error.

I used firebase. firebase used protobuf-lite internelly and maybe it causes confilict. Do you know how to solve the issue? Thank you.

I found similar problems, but it doesn’t work for me.


It is my gradle file.

I found the temporary solution.

add it in app.gradle for solving confilct

THanks,


    configurations {
        implementation.exclude module:'proto-google-common-protos'
        implementation.exclude module:'protolite-well-known-types'

Hi,
It is great to know you already have found a solution and thank you for sharing the solution with the Developer Community.

i.e. For Gradle configuration, you can refer to the ‘Getting-Started ’ page of SDK.

Thank you for answer.

I met issues again.

Once I set configurations, build is ok. samsungwallet transfer works, but google firestore doesn’t work.

I think I should exclude the dependency libraies each implementation. do you know how to exclude libraies each implementation? I am not faimilir with it. Thank you.


    configurations {
        implementation.exclude module:'proto-google-common-protos'
        implementation.exclude module:'protolite-well-known-types'
        implementation.exclude module:'protobuf-lite'
    }
    packagingOptions {
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/plexus/components.xml'
        exclude 'plugin.xml'
    }

Hi,

It is really unfortunate that now you are facing issue with google firestore.

You may find some solution in the following Stack Overflow discussion chain. There is a similar issue like you are facing.

The duplicate class issue maybe related with the firestore version that you are using. You can try to downgrade your firestore version.
