这是我在ionic build android 之后的堆栈跟踪，经过简单的三个步骤即可开始使用ionic：

FAILURE: Build failed with an exception.

所有代码都是$ ionic start myApp tabs自带的默认代码

我尝试更改 gradle 版本，更新 cordova。我也尝试在 build.gradle 中添加这一行：

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

我也这样做了，以防万一： When running the "Cordova build android" I'm getting the below exception

【解决方案1】：

我遇到了同样的问题，我手动安装 gradle 解决了它。

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

我做了这些命令：

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

sdk install gradle 2.1 # Changing 3.1 version to 2.1

我必须重新启动计算机才能正确配置路径。之前我检查了它是否正确配置了 java 和他的路径，但我认为解决它并不重要。
