java-dirq requires maven-javadoc-plugin to be compiled on CentOS/RHEL 8 through EPEL. See #1789677. maven-javadoc-plugin requires maven-artifact-transfer which is not yet in EPEL8. Could you please make maven-artifact-transfer available on EPEL8?
Do you want to maintain the package in EPEL 8? (Or in Fedora and EPEL?) This package is maintained by the Stewardship SIG: https://fedoraproject.org/wiki/SIGs/Stewardship -- the group doesn't generally maintain packages in EPEL.
Thanks for the offer but I do not want to maintain maven-artifact-transfer on EPEL8. Note that my package (java-dirq) has now been built on EPEL8. maven-artifact-transfer (like maven-javadoc-plugin) is still nice to have on EPEL8 but it is not blocking me anymore.
Whoever would like to maintain this package in EPEL 8, feel free to reopen this bug.
