hi, Wondering if it makes sense to extend <detectLink> option to javadoc.io.
For example, google gson (https://github.com/google/gson) has pointed their javadoc to https://www.javadoc.io/doc/com.google.code.gson/gson on their README.md. But currently, maven-javadoc-plugin will only try to fetch https://github.com/google/gson/apidoc/package-list , which apparently is an invalid address. I am aware there is already on option to extend <links> tag, but that's quite tedious as everytime we have to manually keep things in sync when we add / remove dependencies or change versions. There are quite a few popular libraries hosting javadoc with javadoc.io already (eg, mockito / spark), and the pattern is very simple as well: https://www.javadoc.io/doc/[group_id]/[artifact_id]/[version_id]/package-list Thus, it will be quite helpful if maven-javadoc-plugin can just automatically try this url pattern from the dependency list as well. Declaimer, I started javadoc.io about 5 years ago and now it's getting more trendy these days, so I would like to better support this project.
