Java 我正在android studio中尝试使用MQTT协议。我还更新了gradle.properties

为了添加依赖项，我在项目级gradle文件中添加了以下代码

repositories {
maven {
    url "https://repo.eclipse.org/content/repositories/paho-snapshots/"
}

}

在我添加的应用程序级gradle文件中

dependencies {
compile 'org.eclipse.paho:org.eclipse.paho.client.mqttv3:1.1.0'
compile 'org.eclipse.paho:org.eclipse.paho.android.service:1.1.1'

}

获取依赖项解析错误：请在下面查找发生的异常

转到文档以了解如何修复依赖项解析错误。

当您将依赖项jar添加到build.gradle文件，并且libs文件夹中有相同的.jar文件时，会出现重复文件错误。若要消除此错误，请尝试仅使用一种方法，将其保存在build.gradle中或本地的libs文件夹中。

实际上，请尝试使用代码发布所有日志，具体说明您的问题。您可以使用本指南了解如何提问，使其更具可读性。谢谢您的回答，但我以前已经做过。仍然收到相同的错误。您可以发布build.gradle文件并提及您在libs文件夹中使用的所有jar文件吗？是的，非常感谢。。！现在开始工作了。
