When I try to make self-contained installer by jpackage for my modular test project it ends with error:
jdk.incubator.jpackage.internal.PackagerException: jlink failed with: Error: automatic module cannot be used with jlink: io.sentry from file:///C:/Users/....../sentry-1.7.30.jar
Do you have any plans to make Sentry modular that includes module-info.class file?

apparently, we can do it using Gradle

with Gradle and badass-jlink-plugin I have maked self-contained installer, but for now it's impossible using Maven and jpackage tool

Would be nice to see this as part of any work to resurrect OSGi support (#983). Keeping the library JDK8 compatible for now should be of concern as well IMHO.

We are looking to migrate from JDK 11 to JDK 17, and this is a major blocker in our applications preventing the migration to java 9 modules. Can someone please look into this?

@tlf30 would you like to contribute with a PR?

https://docs.gradle.org/current/userguide/java_library_plugin.html#sec:java_library_modular

maybe @maciejwalkowiak can guide you during the process, I'm not familiar with the Java platform module system yet

[maciejwalkowiak]

I have this issue on my todo list, but I will also need some time to dig into it as I haven't worked with JPMS yet. @tlf30 you're welcome to create a PR.

@maciejwalkowiak unfortunately the module system is fairly new to me as well. I have only been learning it these last couple weeks as my company pushes to move from jdk 11 to jdk 17. Our biggest motivator to use modular applications was jfx 16 requiring it, and we are heavily dependent on javafx.

I'm afraid that if I was to prepare a PR that i would overlook something important. I am already fighting that in my own applications.
