尝试使用Glide软件包构建Android项目时，抛出“无法合并dex".错误
问题描述：
我正在运行Android Studio 3.0.我目前正在尝试使Glide 4.3.0版正常工作，但是在4.2.0版中存在相同的问题.
I am running Android Studio 3.0. I am currently trying to make Glide version 4.3.0 work, but had the same issues with version 4.2.0.
我的项目运行良好，没有在我的build.gradle文件中添加Glide软件包依赖项，该文件可从此处下载. https://github.com/bumptech/glide .我也按照这里的设置说明进行操作.首先，我将jar文件添加到我的libs文件夹中，然后添加依赖项.
My project runs fine without adding the Glide package dependencies in my build.gradle file, downloaded from here https://github.com/bumptech/glide. I also followed the setup instructions here too. First I added the jar file to my libs folder, and then added the dependencies.
完整错误是
Error:Execution failed for task
':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.
> com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex
我对此问题进行了很多研究，但只找到了针对其他软件包的解决方案，这些解决方案为这些软件包提供了特定的修复程序，但是我找不到针对该特定软件包的解决方案.
I've researched this issue a lot but only found solutions for other packages which provided specific fixes for those packages, but I wasn't able to find a solution for this specific package.
这是完整的gradle堆栈跟踪.
Here's the full gradle stack trace.

答
问题是将jar文件添加到我项目的libs文件夹中.显然，这造成了重复问题.删除后，我的应用程序运行正常.
The issue was adding the jar file to the libs folder of my project. Apparently, this created a duplication issue. After removing it, my application runs fine.
我天真地这样做是因为我首先在其中使用了Picasso库.我认为这是标准做法.
I naively did this because I used the Picasso library first in which I did this. I assumed it was standard practice.
