更新 Android Studio 后 Gradle 构建错误 [英] Gradle build errors after updating Android Studio

问题描述

我刚刚更新了 Android Studio，现在当我尝试构建我的应用程序时，我收到以下 Gradle 错误:

<块引用>

信息:编译完成，28 秒内出现 2 个错误和 0 个警告信息:2 个错误信息:0 条警告错误:Gradle::java.lang.NullPointerException/Users/mhuggins/Sites/SmoothieFlow/build.gradle错误:(9, 0) Gradle:评估根项目SmoothieFlow"时出现问题.>SDK 目录 '/Users/mhuggins/Library/Caches/AndroidStudioPreview/compile-server/"/Applications/Android Studio.app/sdk"' 不存在.

Android Studio 版本详情:

<块引用>

Android Studio(I/O 预览版)AI-130.709792

Build #AI-130.709792，建于 2013 年 6 月 14 日

JDK 1.6.0_43

VM:Apple Inc. 的 Java HotSpot(TM) 64 位服务器 VM.

有谁知道我为什么会得到这个以及我可以做些什么来解决它?

解决方案

尝试在项目的根目录中添加一个名为local.properties"的新文件(或修改现有文件).它应该包含

sdk.dir=

接下来是sdk位置的路径，在我的例子中

sdk.dir=/Applications/Android Studio.app/sdk

我认为 Android Studio 通常会自动创建一个，但表示不应将其添加到 VCS.我把它放在我的 .gitignore 中并在我的 Mac 上克隆了这个项目，这导致了这个错误.奇怪的是，在 0.1.5 之前，它在没有文件的情况下工作得很好.

I just updated Android Studio, and now when I try to build my app, I get the following Gradle error:

Information: Compilation completed with 2 errors and 0 warnings in 28 sec
Information: 2 errors
Information: 0 warnings
Error: Gradle: : java.lang.NullPointerException
/Users/mhuggins/Sites/SmoothieFlow/build.gradle
    Error:(9, 0) Gradle: A problem occurred evaluating root project 'SmoothieFlow'.
                 > The SDK directory '/Users/mhuggins/Library/Caches/AndroidStudioPreview/compile-server/"/Applications/Android Studio.app/sdk"' does not exist.

Details about Android Studio version:

Android Studio (I/O Preview) AI-130.709792

Build #AI-130.709792, built on June 14, 2013

JDK 1.6.0_43

VM: Java HotSpot(TM) 64-Bit Server VM by Apple Inc.

Does anyone know why I'm getting this and what I can do to fix it?

解决方案

Try adding a new file in the root of your project called "local.properties" (or modify the existing one). It should contain

sdk.dir= 

followed by the path to the sdk location, in my case

sdk.dir=/Applications/Android Studio.app/sdk

I think Android Studio normally creates one automatically but says that it shouldn't be added to VCS. I put it in my .gitignore and cloned the project on my Mac which resulted in this error. Strangely before 0.1.5 it worked just fine without the file.
