Android Studio：无法加载dx.jar [英] Android Studio: Failed to load dx.jar

问题描述

当我在Android Studio中运行我的模块时，我收到此错误：

When I run my module in Android Studio I get this error:

错误：Android Dex：[GradleDevBuild]无法加载dx.jar

Error:Android Dex: [GradleDevBuild] Failed to load dx.jar

我已经无休止地搜索了一个在线解决方案，但一切都与eclipse有关，Android Studio没有任何内容。

I have searched endlessly for a solution online but everything is related to eclipse, there is nothing when it comes to Android Studio.

dex.jar的路径是C：\ AnroidSdk \build-tools \26.0.0 \ lib \ index.jar
所以它确实存在，我已将其移出文件夹并被通知它已移动，因此AS知道它在哪里。我已经尝试将其复制到根目录和platform-tools文件夹中，但是没有做任何事情。

The path to the dex.jar is C:\AndroidSdk\build-tools\26.0.0\lib\dex.jar So it does exists, I've moved it out of the folder and was notified that it moved so AS is aware of where it is. I have tried copying it into the root directory and into the platform-tools folder however that did nothing.

这是所有似乎都源于的错误的完整列表这个dx.jar错误。

This is the full list of errors that all seem to be stemming from this dx.jar error.

推荐答案

我只是在OS X和Ubuntu上清理已安装的Android Studio并遇到同样的问题。通过将构建工具降级到25.0.3来修复。

I just clean installed Android Studio on OS X and Ubuntu and had the same issue. Fixed by downgrading the build tools to 25.0.3.

对于@emjapeve：

For @emjapeve:

• 选择 SDK Manager （工具 / Android / SDK Manager ）。


• 点击 SDK工具标签，默认情况下这是仅显示当前工具版本。


• 选择显示包详细信息复选框。

• Select the SDK Manager (Tools/Android/SDK Manager).
• Hit the SDK Tools tab, by default this only shows current tool versions.
• Select the Show Package Details checkbox.

从这里你可以安装/卸载你想要的任何版本。

From here you can install / uninstall any versions you wish.
