如何修复依赖解析错误？

Question

我正在 libgdx 中开发一个游戏，我正在使用一个外部 jar 来处理 JSON，我知道 libgdx 有它自己的，但我以前使用过这个 jar，我知道如何使用它。无论如何，我将它添加到我的根目录中的 build.gradle 并同步。但是现在当我尝试构建项目时，我收到了这个大错误消息：

我不知道这意味着什么，也不知道这个 org.hamcrest 有什么重复项。这是我的 build.gradle 文件：

}

我唯一添加的是“实现组：'com.googlecode.json-simple'，名称：'json-simple'，版本：'1.1.1'”到我核心项目的依赖项中。 知道如何解决此错误吗？或者是什么原因造成的？

Answer 1

我最终不得不添加：

configurations { compile.exclude group: "junit", module: "junit"}

在 build.gradle 的核心部分，它起作用了。

Answer 2

尝试将以下行添加到应用程序build.gradle 文件中。

android {
    // Some other stuffs
    configurations {
        all*.exclude module: 'org.hamcrest' // This removes all other versions of `org.hamcrest` if gets duplicated from all the artifacts.
    }
    // other stuffs
}
