And like someone already suggested, if you are bundling Jackson jars with something else it is best to ignore module-info.class: I think a few other files often need to be dropped on Android builds. I am interested in hearing more details about problem cases as I realize that just because I haven't yet heard of issues does not mean there are none. But I want to give some context on perceived usage, users, so that issues can be isolated and prevalence correctly estimated. Challenge here is that there is value in providing module descriptors: and I have heard that use of multi-release jars has its own potential problems from tooling perspective. -+ Tatu +- > > > On Tuesday, January 28, 2020 at 2:24:17 PM UTC-8, Ron Karim (Oracle Corp.) > wrote: >> >> In our corporate builds in Oracle that use jackson, we need to support >> JDK 7 and JDK 8 as the current user-base/customers are still on JDK 7 and >> JDK 8 based systems. >> Is there a way of ignoring the JDK 9 module_info.class from these jars ? >> We are not allowed to modify the jars, but the 3 jars need to be in the >> same repository as a single jackson patch. >> >> On Tuesday, January 28, 2020 at 2:14:07 PM UTC-8, Tatu Saloranta wrote: >>> >>> On Tue, Jan 28, 2020 at 11:36 AM Ron Karim (Oracle Corp.) < >>> ron....@gmail.com> wrote: >>> >>>> Basically Dependencies rejected for these 3 jars with the >>>> module_info.class (as it is different in all 3 jars). >>>> Is there a version 2.10.2 available with support for >>>> multi-release-jars ? >>>> >>> >>> No. Module-info classes should only be used by JDK 9 and above; Java 8 >>> and below should just ignore these classes. >>> >>> What specifically is your issue?
