hi @Baitanik_Talukder ,
Interesting case you have here
Our analyser, as @ganncamp said, was not designed to analyse two separate repo in the same SonarQube project.
My suggestion would be to
build your plugin_a, publish it as a node package and analyse it with a separate SonarQube project. (Then add the dependancy for ui_main)
OR use a monorepo setup where both ui_main & plugin_a are in the same repo but different folders. Then you can analyse the full monorepo with SonarQube
