Robert Važan commented on MJAVADOC-656:
---------------------------------------
[~michael-o]: Is that a per-link parameter or a global parameter? In any case,
instead of adding a flag to disable broken functionality, it would be better to
just fix it. Do not assume anything about how root path is redirected. Resolve
redirects for fully formed URLs of machine-readable resources like
/package-list and /element-list. That will work everywhere without
configuration.
> Following redirects breaks valid links

> Key: MJAVADOC-656
> URL: https://issues.apache.org/jira/browse/MJAVADOC-656
> Project: Maven Javadoc Plugin
> Issue Type: Bug
> Affects Versions: 3.0.1, 3.2.0
> Reporter: Robert Važan
> Priority: Minor
>
> Version 3.0.1 fixed #427 by following redirects. This feature unfortunately
> breaks when HTTP server is configured as follows:
> /apidocs/package-list -> 200
> /apidocs -> 301 /apidocs/com/example/package-summary.html
> /apidocs/ -> 301 /apidocs/com/example/package-summary.html
> /apidocs/com/example/package-summary.html -> 200
> Without following redirects (in version 3.0.0), the link is passed to javadoc
> tool unchanged, the javadoc tool fetches /apidocs/package-list, and
> everything works fine. Since 3.0.1, javadoc plugin follows one of the
> redirects (/apidocs or /apidocs/), passes the package summary URL to javadoc
> tool, which then fails like this:
> [WARNING] javadoc: warning - Error fetching URL:
> [https://example.com/apidocs/com/example/package-summary.html/]
> And if you have failOnWarnings set to true, this will fail the whole build.
> The solution is fairly simple. Construct the whole URL (.../package-list) and
> follow redirects on that one. Then check whether the final destination ends
> in /package-list, strip the /package-list suffix, and pass the result to the
> javadoc tool.
