Are you using any 3rd party plugins? Have any of them been updated recently? Try removing them and adding them back in until you find the offending plugin.
When you use third-party plugins without specifying a version number you always get the "latest" version of the plugin. Unfortunately, this means that what you built against 20 days ago may be different than what you built against today. This is resolved by the EA version of the XDK, which handles plugins differently (see this post for instructions on how to download), but not by the current version of the XDK. So it is likely that one of your plugins was updated by the plugin author and that broke the build.
Yes i think what ever you are saying is right.but in my project i did not using any third party plugins we are using our own custom plugins and also some plugins which are download from net and then we are using.But we are not giving any direct reference.
@Nagajyothy -- we refer to any plugin, other than the core plugins, as "third-party plugins." Sorry for that confusion. If your plugins are all stored locally in the project, and nothing in that project changed, then my suggestion is invalid. If, however, any of them is stored outside your project, you could be subject to what I am describing. I hope that makes sense.
