Create custom Fiori Client with Kapsel from SPM Sdk SP10

Dear experts,

I am trying to generate a customized Fiori Client just as explained in the brilliant Getting Started with Kapsel - SAP Fiori Client (SP09+) blog.

I am facing an error as I launch the node create_fiori_client.js :

This problem has been described here but no significant solution was found... I found the obvious solution that consists in modifying the create_fiori_client.js script to get rid of the launchmyapp plugin part.... Thus, I have commented line 120 of the script and successfully built my android Fiori client.

The question is : how much do I need this plugin because the application does not build in Android Studio ?

Thanks,

J.
