解决办法：

修改 \platforms\android\CordovaLib目录下的 build.gradle 文件：

 repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }

改成

repositories {
        jcenter{url "http://jcenter.bintray.com/"}
        maven {
            url "https://maven.google.com"
        }
    }

再重新编译成功！
