How to install jpackage-gradle-plugin?

[HiranChaudhuri]

I am not yet familiar with gradle but trying to add JPackage steps into an existing gradle-built project. By adding lines such as in https://github.com/petr-panteleyev/jpackage-gradle-plugin/blob/master/doc/examples/Non-ModularApplication.md I am getting this error:

$ ./gradlew jpackage
To honour the JVM settings for this build a single-use Daemon process will be forked. See https://docs.gradle.org/7.3.3/userguide/gradle_daemon.html#sec:disabling_the_daemon.
Daemon will be stopped at the end of the build 
WARNING: Android is disabled.
To enable Android build, download the Android SDK. Then create a file local.properties with the following content:
    sdk.dir=<path to sdk>

So now I am wondering why my gradle installation should find your gradle plugin. Something is still missing, isn't it?

Did you add this plugin to your build? https://plugins.gradle.org/plugin/org.panteleyev.jpackageplugin

Closing the issue cause it's not the plugin bug.

While I agree it is not a plugin bug, would it be worth adding a line or two to the documentation you created? It is not obvious that this plugin has made it's way to the gradle plugins site, and on https://plugins.gradle.org/plugin/org.panteleyev.jpackageplugin you can read how to add the plugin but not how to use it.

Plugin portal gives an information how to import plugin. Plugin docs show how to use it. I don't plan on describing gradle basics while there are tons of docs on gradle site. Besides I would need to cover both Kotlin and Groovy and I don't really care about Groovy DSL at all.
