Cordoba 3.5, how to update a local plugin?

Question

I just created my first Cordova plugin and I would like to ask how can I reflect the changes in the files located in:

/app/plugins/org.cool.plugin

I changed the contents of the plugin.xml file and added the code to the Java class.

After that, I ran the cordova build android command , but the changes are not available in the platforms / Android / CSI / ...

I would like to ask how can I get the rebuild plugin instead of manually copying files?

Thanks so much for any help.
