我用新的SDK工具更新了Eclipse (rev. 23)，但现在当Eclipse启动时，我收到了错误:
此Android SDK要求Android Developer Toolkit版本23.0.0或以上。当前版本为22.6.3.v201404151837-1123206。请更新ADT到最新版本
“检查更新”没有发现更新。如果我尝试“安装新软件”，我可以看到版本23，但由于以下错误，我无法升级:
Cannot complete the install because of a conflicting dependency.

从网站下载上一份ADT后，似乎又出现了一个问题。
没有安装SDK Tools rev. 23 proguard，文件夹SDK dir/ Tools /proguard丢失，其他工具也丢失。这个版本包含几个错误。
我在Mac OS X 10.9.3上得到了同样的“依赖冲突”错误，简单地升级是一个选项。最终起作用的是从developer.android.com下载最新的Eclipse ADT包压缩文件，提取它并将“Eclipse”文件夹移到我原来的Eclipse文件夹所在的位置。(解压Eclipse ADT包压缩文件会给你“Eclipse”和“sdk”文件夹)。
如果您决定走相同的路线，首先要确保您知道您的Workspace路径是什么。这可以在Preferences中找到。然后将旧的“eclipse”目录(不是eclipse .app)重命名为类似eclipse-22.6.3的目录，然后将解压缩的“eclipse”文件夹移动到相应的位置。运行新的Eclipse。当它问你关于Workspace的问题时，只需要输入与上面提到的相同的路径。或者也可以稍后在Preferences中设置。
也许值得添加的是，重新启用Android SDK管理器和Android虚拟设备管理器选择窗口->自定义透视图->命令组可用性，并选择Android SDK和AVD管理器。这将把这两个项目添加到当前透视图(Java)的“Window”菜单项中。
我没有移动提取的“sdk”文件夹，因为我已经在eclipse的同一目录下有sdk文件夹，我已经更新到最新的Android工具。但是如果这让您感觉更安全，您还可以重命名您的旧sdk文件夹(出于备份目的)，并将新提取的sdk文件夹移到原来的位置。
在尝试了其他答案中的方法后没有成功，我只是从http://developer.android.com/sdk/installing/index.html?pkg=adt安装了一个新的捆绑包，效果很好。
做以下几点:
As you don't want to re-download all the platforms again, copy the existing one from /OLD_ANDROID_SDK_PATH/sdk/platforms to /NEW_ANDROID_SDK_PATH/sdk/platforms.
When opening the new Eclipse from the recent downloaded bundle, make sure you reuse the previous 'workspace' folder. That will ensure that all your previous settings will be remembered.
After opening the new Eclipse on the previous workspace, please check if the used Android SDK is pointing to the new one (Eclipse preferences -> Android). It might be pointing to the old one, as you've reused the previews workspace settings.
通过这些步骤，您不应该重新配置所有内容，也不需要花费时间从谷歌开发人员升级时排除此BUG。
好运！: -)
我已经做了以下来解决一个问题。
Go to http://developer.android.com/sdk/installing/installing-adt.html and download the latest ADT ZIP file (at the bottom of page).
Go to Eclipse → menu Help → About Eclipse → Installation details
Delete Android DDM, Android Development Tools, Hierarchy Viewer, Native Development Tools, TraceView, etc., 22.X version.
Menu Help* → Install New Software → Add → Archive → *Select the downloaded ZIP file in step 1.
Select all the latest version of all 23 which I have deleted in step 3 and accept the license agreement.
重新启动Eclipse，它就修复了我的问题。
