Admob integration fail in cocos2d-js v3.6.1 (sdkbox-admob_v2.2.1.6)

Yes I have done like that only. I have gone through all the steps from creating project to integrating sdkbox . however my project cant find sdkbox.jar path. I have created new project as well and the issue is same for all the projects. How to resolve this issue ?

Can you tell me how you build your project? Using cocos code ide?

I followed this Link- https://www.youtube.com/watch?v=VLeGy1foMQA.
1-> Create a project on cmd command (cocos new project_name -p package.name.com -l js -d path )
2-> Then compile the project on cmd command (cocos compile -p android ).
3-> Open cocos code ide ->select file ->select new -> select project from Existing sources ->select project folder
4-> Then include 4 folder (platform/android/java, platform/android/java/src, proj.android/gen, proj.android/src )
5-> uncheck all plugin.
6-> Select android API 21 Platform.
7-> Then finish the import.
8->Then follow the link -> http://docs.sdkbox.com/en/plugins/admob/ to import admob
9-> import admob in cmb command (f:\cocos_project\project_name > sdkbox import admob)
10 -> Then run the project in cocos code ide.
