When building a modular gradle project with openjdk14 as build environment, is it neccessary to specify a java module structure with java9 modules (module-info.java) as well or can you just use a plain jar? When doing a module-info.java with the line “requires kotlin.stdlib” we get the following error when building:

module-info.java:2: error: module not found: kotlin.stdlib
    requires kotlin.stdlib;
                   ^
