I once encountered the same error after updating Android Studio and SDK.
我曾经在更新 Android Studio 和 SDK 后遇到同样的错误。
You could try to use 'com.android.tools.build:gradle:1.3.0'instead of 'com.android.tools.build:gradle:1.2.3'in Project gradle file.
您可以尝试在 Project gradle 文件中使用'com.android.tools.build:gradle:1.3.0'而不是'com.android.tools.build:gradle:1.2.3'。

Changing from 7.5.+to 7.5.0fixed this issue for me. I'm not sure why the wildcard caused an issue.
从改变7.5.+到7.5.0修复了这个问题对我来说。我不确定为什么通配符会导致问题。

I know this question has been answered well but just to add something for those who come across a similar error and are seeing this page.
我知道这个问题已经得到了很好的回答，但只是为那些遇到类似错误并看到此页面的人添加一些内容。
Failed to resolve usually pops up when you are updating the dependencies (read google support libraries) to a newer version and your project is using older version of Google Play Services (look in Android SDK Manager under Extras).
当您将依赖项（读取 google 支持库）更新到较新版本并且您的项目使用较旧版本的 Google Play 服务（查看 Extras 下的 Android SDK 管理器）时，通常会弹出无法解决。
To resolve this just update the Google Play Services to the latest version and then Sync your build.gradle (app). This should resolve similar issues.
要解决此问题，只需将 Google Play 服务更新到最新版本，然后同步您的 build.gradle（应用程序）。这应该可以解决类似的问题。

For what it's worth, I had this error when I updated from 10.1.1 to 10.2.0. I tried using 10.2, but found that I had to use the full version number: 10.2.0 (the last zero matters). Hope this helps someone.
值得一提的是，当我从 10.1.1 更新到 10.2.0 时遇到了这个错误。我尝试使用 10.2，但发现我必须使用完整版本号：10.2.0（最后一个零很重要）。希望这可以帮助某人。

For me - help:
对我来说 - 帮助：
- to go to Tools -> Android -> SDK Manager
- in Android SDKfrom left list choice tab SDK Tools
- Check all need to updatepackages
- You need a lot of free space on disk and a lot of time (for me with SSD disk it takes about 1 hour)
- 转到工具 -> Android -> SDK 管理器
- 在Android SDK 中从左侧列表选择选项卡SDK Tools
- 检查所有需要更新的软件包
- 您需要大量的磁盘可用空间和大量时间（对我来说，使用 SSD 磁盘大约需要 1 小时）
After that your project should work fine.
之后，您的项目应该可以正常工作。
