When I run my project it comes like this

 04:41:35: Executing task 'Launcher.main()'...

Hey @parasuraam , if you want to have a modular build, you must use jlink plugin instead of runtime plugin. YOU MUST ALSO READ THESE DOCS CAREFULLY https://badass-jlink-plugin.beryx.org/releases/latest

Then , how can I build the jpackage ?

[Srijan-Sengupta]

according to the docs, jpackage task is already given. If you want to configure the jpackage build, read these to do so, https://badass-jlink-plugin.beryx.org/releases/latest/#_jpackage .
