離子構建android在Ubuntu上拋出``無法解析com.android.tools.build:gradle:2.1.0''

Question

這是在ionic build android之后的我的stacktrace，經過三個簡單的步驟即可開始使用ionic ：

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'android'.
> Could not resolve all dependencies for configuration ':classpath'.
   > Could not resolve com.android.tools.build:gradle:2.1.0.

所有代碼都是$ ionic start myApp tabs附帶的默認代碼。

我試圖更改gradle版本，更新cordova。 我也嘗試在build.gradle中添加以下行：

repositories {
        maven { url 'http://repo1.maven.org/maven2' }
    }

我也這樣做，以防萬一： 運行“ Cordova build android”時，出現以下異常

我有同樣的問題，我解決了手動安裝gradle的問題。

https://gradle.org/gradle-download/

我做了以下命令：

curl -s https://get.sdkman.io | bash

sdk install gradle 2.1 # Changing 3.1 version to 2.1

我必須重新啟動計算機才能正確配置路徑。 以前我檢查過它和java及其路徑的配置是否正確，但是我認為解決它並不重要。
