Gradle 添加 discord4j 库后出错

Question

我正在尝试使用 discord4j 构建一个 discord 机器人。我将这行代码添加到 build.gradle 文件中。

dependencies {
    implementation "com.discord4j:discord4j-core:3.2.2"
}

但是，在我尝试构建应用程序后，构建在任务 :app:checkDebugDuplicateClasses 处失败。

Execution failed for task ':app:checkDebugDuplicateClasses'.

我注意到模块 discord4j-rest 和 discord4j-voice 中有重复的 class。搜索解决方案后，我发现 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,

但是，这2个模块是discord4j的依赖项。因此，我无法对它们使用 force 函数。我该如何解决这个问题？

Answer 1

我是 Discord4J 的开发人员之一，pushed a fix 将受影响的 class 移动到共享模块。

在没有包含它的稳定版本之前，您可以切换到最新的快照来尝试。

repositories {
  maven { url 'https://oss.sonatype.org/content/repositories/snapshots' }
  mavenCentral()
}

dependencies {
  implementation 'com.discord4j:discord4j-core:3.2.3-SNAPSHOT'
}
