👋 Hello, team! We are getting the below error while running the command on windows, unable to download the plugin, Could you please help here?

There is no sourceSet() function, only getSourceSet()

That's not correct @Philip W. What he has is

sourceSets { ... }

Which is perfectly fine. There is just "something" wrong in the

...

part and this is the usual "Groovy DSL often gives non-helpful error messages" problem. You can either comment everything inside and uncomment bit by bit to find the problematic line(s). Or what I would recommend, switch to Kotlin DSL. By now it is the default DSL, you immediately get type-safe build scripts, actually helpful error messages if you mess up the syntax like in this case and amazingly better IDE support if you use a good IDE like IntelliJ IDEA or Android Studio. No idea though what you mean by "unable to download the plugin", as that is not part of your screenshot. Btw., please never anywhere share screenshots of text if you only want to share the text and not something additional like colors or IDE annotations. Text in images is hard to read, especially on mobile, very hard to copy, and nearly impossible to search for.
