add module-info.class for Java9+ modular system #962

Could you add module-info.class to Time4j for Java9+ modular system?

MenoData commented 2 years ago

Thanks for your feedback. I have already thought about it and done some experiments with build configuration. But I have not found any good way to achieve compatibility with both Java 8 and modular Java 9.

So I get the impression to abandon compatibility with Java 8 and just switch over to Java 9. However, I am not sure how other users would think about this option.

Maybe you can try adding this build configuration to your pom.xml: maven-compiler-plugin: Older projects with module-info

I have struggled a long time with this issue but finally I have to say: Sorry, will not implement it at least not in this or next year. Maybe later when Java 8 is much more out of common usage. Main reasons:

A date- and time-library does not urgently need modules.
I have not found any good way to release a build which will work on Java-8 AND with modules on Java-9 AND will work in my development area.
At least automatic module names are already supported.
