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。
如何从22.xx更新。X到23.0.2(我的解决方案)。这将解决依赖性问题。
我被这个问题折磨了几天，我已经尝试了这个环节上的每一个解决方案，但运气不好。我终于想出了一个真正有效的解决方案!
请注意，此解决方案适用于Windows 7(64位)。它应该适用于其他Windows操作系统。
开始吧:
download the latest ADT bundle from
http://developer.android.com/sdk/index.html#download
unzip it and open "eclipse" folder --> "plugins" folder
Now go to your old eclipse and open "eclipse" folder --> "plugins" folder, and copy everything inside.
Now paste them into the "plugins" folder of the (NEW ECLIPSE), but DO NOT overwrite anything.
While inside of the "plugins" folder of your new Eclipse, do the search. Type in 22. (notice 22 with a dot) and hit enter.
The search result will show up all the files or folders with .....22.6...... For example,
com.android.ide.eclipse.adt_**22.6.2**.v201403212031-1085508
Highlight all of these files/folders and hit delete key.
Make sure to update your old API/SDK to the latest version and load this sdk directory to work with your new eclipse.
or
您可以观看这个视频，它向您展示如何将所有SDK/API移动到新的SDK文件夹。

我没有尝试从任何其他ADT版本更新，但我认为它应该适用于任何旧的ADT版本。
尝试之前不要忘记备份。
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！: -)
注意:请谨慎使用这种方法，因为这可能会破坏Eclipse安装(请参阅注释)。
如果您手动安装ADT插件，这可能会对您有所帮助。但是如果您正在使用Eclipse ADT Bundle中的Eclipse版本，那么以下步骤可能会破坏您的Eclipse安装，并且您可能无法再次使用Eclipse !
去
菜单帮助→关于Eclipse SDK→安装详细信息。
现在你会看到所有的22.0版本，然后点击底部的卸载按钮。
卸载后转到:
菜单帮助→安装新软件→输入http://dl-ssl.google.com/android/eclipse/
然后安装所有的东西，现在就准备好了。
