Cordova错误(ERROR构建其中一个平台)

Question

我一直在node.js中构建我的phonegap应用程序没有任何问题.突然,当我现在尝试构建时,它显示一些错误,并且没有创建apk.

这是错误:

C:\testapp\platforms\android\cordova\node_modules\q\q.js:126
                    throw e;
                          ^

s\android\build.xml -Dout.dir=ant-build -Dgen.absolute.dir=ant-gen"

我没有调整任何系统设置/属性.我没有更改或卸载任何东西.这突然发生了.我尝试重新启动但它没有用.
