Cordova - Why does my installation fail on windows?

Windows has a maximum file path length which means that it is not possible to create new folders after a certain depth in the file system has been reached. Since adding a plugin copies files in an already quite deep folder structure an install can fail because the maximum file path length has been reached and the system fails to copy all the files necessary. To avoid this move your project as high up in the file system as possible (to something like C:\yourProject).
