尝试使用 Glide 包构建 Android 项目，抛出“无法合并 dex”错误答案

【问题标题】：Trying to build Android project with Glide package, throws "Unable to merge dex" error尝试使用 Glide 包构建 Android 项目，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，但在 4.2.0 版中遇到了同样的问题。

我的项目运行良好，无需在我的 build.gradle 文件中添加 Glide 包依赖项，从这里下载 https://github.com/bumptech/glide。我也按照此处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，然后添加了依赖项。

完整的错误是

Error:Execution failed for task 
':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.
> com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

我对这个问题进行了很多研究，但只找到了其他包的解决方案，这些包为这些包提供了特定的修复，但我找不到这个特定包的解决方案。

这是完整的 gradle 堆栈跟踪。

【问题讨论】：

我建议您编辑您的问题并发布您的 Gradle 控制台的整个输出，而不仅仅是那一行。您的问题的详细信息位于输出的其他位置。
@CommonsWare 刚刚做到了。感谢您的建议。
嗯...尝试将C:\Users\Alex\.gradle\caches\modules-2\files-2.1\com.github.bumptech.glide 移动到某个临时位置，然后重新构建。也许你有一个损坏的 JAR。如果问题仍然存在，我会向 Glide 提出问题，因为他们的 JAR 可能需要修复。您也可以尝试暂时降到4.2.0。
嗯，我遇到的所有 DexMerger 都是关于将 gradle.properties 更新为 4.3 你会尝试吗？
@CommonsWare 我也尝试了 4.2.0 版，但也很幸运。

【解决方案1】：

问题是将 jar 文件添加到我的项目的 libs 文件夹中。显然，这造成了重复问题。删除后，我的应用程序运行良好。

我天真地这样做了，因为我首先使用了 Picasso 库。我认为这是标准做法。

谢谢！，拯救了我的一天。
