找不到com.google.firebase:firebase-database:9.2.0 [英] Could not find com.google.firebase:firebase-database:9.2.0

问题描述

我正在尝试将新的firebase数据库安装到我的应用中，但是由于下一个错误而失败:

I was trying to install new firebase database into my app, but it was failed with next error:

错误:找不到com.google.firebase:firebase-database:9.2.0.必需的 经过: appName:app:未指定

Error:Could not find com.google.firebase:firebase-database:9.2.0. Required by: appName:app:unspecified

我从此处克隆了Google的官方示例，并尝试构建数据库示例，但是我仍然出现相同的错误...

than i clone official google example frome here and was trying to build database example, but i still get same error...

看起来像是因为某些Google错误.我对吗? 在其他情况下，为什么会发生这种情况以及如何解决呢?

looks like this is because of some google error. am i right? in other case, why it happens and how to fix this?
