In the default elasticsearch installation we use plugin install to install plugins.
So how to install plugins through the compiled source code of elasticsearch in eclipse

I don't understand the question.

I run elasticsearch instance by gradlew run.
I am not using normal installer ,so how do i install plugins

I wonder if you run gradle run from the plugin dir, would that work?

I honestly don't know. Most of the time, I'm doing that manually once I'm done with plugin development.
