I am trying to build an discord bot with discord4j. I added this line of code to the build.gradle file.
dependencies {
implementation "com.discord4j:discord4j-core:3.2.2"
}
However, after I try to build the app, the build failed at task :app:checkDebugDuplicateClasses.
* What went wrong:
Execution failed for task ':app:checkDebugDuplicateClasses'.

I noticed that there is a duplicate class in modules discord4j-rest and discord4j-voice. After searching for the solutions, I found this answer:
Sometimes duplicate classes exception means that one of your dependencies uses implicitly the older or newer (with ) version of some library you also use in your project,
However, these 2 modules are the dependencies of discord4j. Therefore, I am not able to use the force function with them. How can I solve this problem?
CodePudding user response：
I'm one of the developers for Discord4J and have pushed a fix moving the affected class to a shared module.
Until there's a stable version including it, you could switch to the latest snapshot to try it.
repositories {
maven { url 'https://oss.sonatype.org/content/repositories/snapshots' }
mavenCentral()
}
dependencies {
implementation 'com.discord4j:discord4j-core:3.2.3-SNAPSHOT'
}
