原因

Android plugin 升级到3.0之后， platforms\\android\\app\\build.gradle 文件中 outputFile 变成了只读属性。

解决办法

1.  用 all() 代替 each() 
2.  用 outputFileName 代替 output.outputFile

修改之前 platforms\\android\\app\\build.gradle 的内容如下：

修改之后 platforms\\android\\app\\build.gradle 的内容如下：

applicationVariants.all { variant ->
            variant.outputs.all {
                outputFileName = "${variant.name}-${variant.versionName}.apk"
            }
        }
