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。
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！: -)
谷歌发布了ADT v23.0.2。这解决了之前ADT版本23的许多问题。
循序渐进:
菜单帮助→安装新软件…
对于“Work with”，选择Android源代码https://dl-ssl.google.com/android/eclipse
勾选ADT v23.0进行安装，然后点击“下一步”
Eclipse将显示“安装修复页面”，因为与以前的版本有冲突。(如果没有，请参见下文。)选择“更新我的安装使其与正在安装的项目兼容”以卸载旧版本并安装新版本。之后，按照通常的步骤进行。
注意:当我安装新版本的ADT时，我没有包括新版本的“Android原生开发工具”包。相反，我先安装了其余的包，然后安装了“Android原生开发工具”。由于某种原因，如果我尝试安装包括“Android原生开发工具”在内的所有新包，安装会失败。
如果没有“补救页面”，从Eclipse中删除ADT插件的唯一方法是进入菜单帮助→关于Eclipse→安装详细信息并从那里卸载。但是存在卸载Eclipse本身的风险。
他们是这么说的
好了，伙计们，很抱歉给你们带来这么多麻烦，我们为混乱的发布道歉。总结如下:
There is no way to update an existing ADT bundle that you might have downloaded.
You can do one of two options:
Install Eclipse from eclipse.org and install ADT by pointing to the update site: https://dl-ssl.google.com/android/eclipse
Download bundles from here:
Linux 64-bit VM: http://dl.google.com/android/adt/adt-bundle-linux-x86_64-20140702.zip
Linux 32-bit VM: http://dl.google.com/android/adt/adt-bundle-linux-x86-20140702.zip
Mac: http://dl.google.com/android/adt/adt-bundle-mac-x86_64-20140702.zip
Windows 32-bit: http://dl.google.com/android/adt/adt-bundle-windows-x86-20140702.zip
Windows 64-bit: http://dl.google.com/android/adt/adt-bundle-windows-x86_64-20140702.zip
从ADT bundle 23.0.2开始，您应该能够更新到ADT的未来版本。
