我更新了cordova来解决，但是几天仍然还是一样的错误

I have updated my cordova to resolve but still same error however a few days ago it was working fine and i have build some apps.

推荐答案

首先从以下链接下载Cordova jar文件：

First download Cordova jar file from following link:

http： //www.java2s.com/cn/Code/JarDownload/cordova/cordova-1.8.1.jar.zip

之后，将文件夹解压缩并放入cordova -1.8.1在eclipse中的项目的libs文件夹中

after that extract the folder and put cordova-1.8.1 inside your libs folder of project in eclipse

然后右键单击您的项目->属性，然后从左侧窗格中选择Android，然后滚动到底部，删除cordova库。

And right click on your project--> properties and Select Android from left pane and scroll to bottom remove the cordova library if added.

然后清理并构建您的项目。

then clean and build your project.
