Cannot install plugin cordova-sqlite-storage

I want to install cordova-sqlite-storage. But i got error message bellow: enter image description here

I have tried to unzip the Cordova-sqlite-storage-master-public.zip to the "D:\Project\hello\platforms\android\platform_www\plugins\cordova-sqlite-storage" but I'm not sure if this works or not because I cannot see the plugin in eclipse after I have cleaned the project.

I'm new to Cordova. Can anyone help? Thanks in advance.
