【问题描述】：
本周末我试图将一些项目迁移到 Android Studio，但遇到了一些障碍。我的最后一次尝试涉及使用带有插件版本 22.0.5v201307292155-757759 的 Eclipse ADT 创建一个简单的 Hello World Android 项目。我创建了这个项目，目标是 Android 版本 4.2 w/最低 SDK 2.3 并使用 4.3 构建。我对 AVD 进行了快速构建/运行测试，结果很好。然后，我按照迁移文档中的说明，将项目导出并为 Android Studio 生成了我的 Gradle 构建文件。当我尝试使用捆绑的 gradle 分发 (1.7) 导入 Android Studio 0.2.6 Build# AI-130.795381 时出现错误：“原因：未能找到目标 android-18”，idea.log 中有堆栈跟踪：
2013-08-31 16:04:31,465 [ 517146] INFO - ject.ProjectImportErrorHandler - Failed to import Gradle project at '/Users/clifton/workspace/MyOtherLilAndroid'

当我尝试使用 Gradle Wrapper（推荐）时，我收到一个错误：无法使用 Gradle 分发版“http://services.gradle.org/distributions/gradle-1.6-bin.zip”执行构建。 构建文件'/Users/clifton/workspace/MyOtherLilAndroid/build.gradle' 行：9 评估根项目“MyOtherLilAndroid”时出现问题。 评估根项目“MyOtherLilAndroid”时出现问题。 未找到 SDK 位置。使用 local.properties 文件中的 sdk.dir 或使用 ANDROID_HOME 环境变量定义位置。
idea.log 中有以下堆栈跟踪：

我尝试下载 Gradle 1.7 并将其用于导入，但我收到另一个错误：“原因：找不到目标 android-18

我已经确认 ANDROID_HOME 是通过“~/.MacOSX/environment.plist”在我的 Mac 上设置的，并且在我的“~/.bashrc”中设置，它是由我的“~/.bash_profile”最后我尝试过的在项目的 local.properties 中设置 sdk.dir 和 ndk.dir。使用捆绑的 gradle 我在 idea.log 中收到此错误：

org.gradle.tooling.BuildException: Could not fetch model of type 'AndroidProject' using Gradle distribution 'http://services.gradle.org/distributions/gradle-1.6-bin.zip'.
还有这个带有 gradle wrapper 的堆栈跟踪：

什么给了？有没有人成功地将项目迁移到 Android Studio？我在一个糟糕的时间尝试吗？我了解这些工具仍在大力开发中。请指教。
【问题讨论】：

我只是设法让一些东西有点工作。我使用 Android Studio 创建了一个“hello world”项目，并将它的 build.gradle 复制到我导出的 Eclipse 项目中，并使用捆绑的 gradle distro 1.7。显然，Eclipse ADT 导出的 build.gradle 和 Android Studio 生成和期望的 build.gradle 有很大不同。

我想我可能正在解决这个问题。在强制我的项目进入 AS 后，由于项目没有完全定义，我无法创建运行配置并遇到几个与路径相关的问题。出于某种原因，Eclipse ADT 将项目标记为使用构建工具修订版 18.0.1 构建，这导致了上面的原始“未能找到目标 18”错误。更新我的 gradle 构建以使用 buildTools 17 似乎满足 gradle 同步和导入工具。稍后会详细介绍。
