exportAllPackages() breaks module for multi-release jar packages

[crschnick]

I am using extra-java-module-info v1.5 to modularize the dependency org.kohsuke:github-api:1.317. When using exportAllPackages() it somehow breaks with an invalid module exception caused by a multi-release package being exported. So for now I export all packages manually and that works for me like this

Thanks for reporting.
