raw ebuild as created by java-ebuilder
java-ebuilder presently puts HOMEPAGE exactly as given in the pom file. Those HOMEPAGEs are outdated in many cases.
PFA jdbc-mysql-8.0.25-r2.ebuild as an example.
java-ebuilder should check HOMEPAGE and overwrite any outdated url with eventual redirect target.
Also, it would be great if HOMEPAGE can be an HTTPS URL when possible too. Currently, many ebuilds generated by java-ebuilder still use HTTP URL for HOMEPAGE.
