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。
我遵循了这里找到的说明，并试图修复我的旧Eclipse + SDK + ADT，但没有运气。基本问题是一样的;我仍然得到错误消息:
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
但是我的eclipse找不到更新，也不能将ADT 23作为新软件安装。所以我不能在我的工作区编译我的旧项目。
I tested a fresh eclipode bundle for Windows 8, followed instructions found from Android's developers page, step by step, and it worked fine. So it seems that the Windows Eclipse build is not broken. But I wan't use my Linux installation, my old Ubuntu 10. It seems obvious, that to getting the Linux Eclipse environment working again, I must install a new Eclipse bundle, my old Eclipse won't ever see updates for ADT 23 to get things working. Again, these intructions are for Linux developers that wan't to get their old workspace projects working again without changes in the developing environment, except you must install a new Eclipse bundle, but after that your projects will work as well as before the version 23 SDK/ADT-mess.
If you are an Android developer you want to be sure, that you developing environment won't be messed up. Backup:
~./android (Here are your developer keys)
Your old SDK dirrectory
Your workspace
Download the Eclipse bundle, Get the Android SDK.
Follow instructions, create directory ~/Development and unzip bundle there. You get Eclipse and SDK directories.
Start Eclipse from that directory
Eclipse asks for a workspace. You can give it the old one.
In Eclipse settings set SDK as downloaded SDK.
Start Android SDK manager and download tools, Android versions you use and extras said in the Android developer tool page instructions
You should now be ready to compile your old projects again, but for me it was not that simple. My old projects had errors. So open problems windows and you get to know that annotation.jar is missing. So you must copy annotations.jar from your old SDK, from, the backup you made, or from the older sdk.zip explained in this thread to <new SDK>/tools/support/annotations.jar
在那之后，我可以使用我在Ubuntu中的旧工作区，并在Android设备上编译和启动应用程序。就是这么简单。谢谢谷歌;-(
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。
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。
