I\'m looking for a way to convert the javadocs from my open source project (generated in Eclipse) to GitHub MarkDown, or come up with some other s
It might be a bit off topic but I believe what OP is looking for is a mechanism to automatically make javadoc available as a new version of the project is published.
If this is the case, then you can try: http://javadoc.io
It's a free service hosting javadocs for open source project, currently supporting maven central and bintray (jcenter).
You can generate a link to the latest version of your project. For example, this link https://javadoc.io/doc/org.springframework/spring-core always point to the latest version of spring-core, which is 5.2.0.RELEASE at the time I write this answer.
Declaimer: I run javadoc.io
