We closing your issue as duplicate, to keep all reasons in one place.

@romani I've started looking into this. Once I have a modular build working correctly, I will post it to the JPMS Attic repository where it can be tested easily with other libraries.

I've already done the work to ship modular Guava and other dependencies that Checkstyle needs. In fact, I'm using Checkstyle's build as an integration test against modular-enabled Guava and Protobuf. It's already passing.

So, doing the work to modularize Checkstyle, and then promoting it from a test in that repo to a library available in the JPMS Attic is not so hard.

I'll check back in when I have news which shouldn't be too long.

Is it same as #14120 ?

What is jlink ?

What is jlink ?

jlink tool is kind of partially similar to docker but exclusively for java. Like images to containers in docker, jlink generates a java image which usually contains modules that are required to run the application.
It is more of a customizable option where we can pick the modules. So yes, a custom image is created using jlink

@rnveach Thanks that's a good point and should make things easier.

@romani Why was this closed? An Automatic-Module-Name isn't the same as a module-info.java... it might be a duplicate of #14139?

Ah, understood @romani. Thank you for explaining 👍
