Wex5打包报错的解决办法

以前使用Wex5 3.6打包没有任何问题，这次生成Android安装包时，报错如下：

这里真正出错的代码是这段：

D:\Java\WeX5_V3.6\model\Native\ztest\build\src\platforms\android\gradlew cdvBuildDebug -b D:\Java\WeX5_V3.6\model\Native\ztest\build\src\platforms\android\build.gradle -Dorg.gradle.daemon=true --offline

产生的错误是这个：

> Could not resolve all dependencies for configuration ':classpath'.> Could not resolve com.android.tools.build:gradle:2.0.0+.

找不到classpath指向的gradle文件。

我把上面的命令在命令行执行，并启动–debug，结果发现该命令执行的时候是到maven的库文件里去找，maven库里没有gradle。以前没有安装maven的时候打包不报错，现在安装了maven，打包的时候会到maven的库里去找。所以在maven的pom里把gradle添加进去，下载到本地资源库，再打包就没问题了。如果你安装了maven并且错误提示里也是缺少了gradle或者别的什么包，可以用这种方法解决。
