> Following redirects breaks valid links
> --------------------------------------
>
> Key: MJAVADOC-656
> URL: https://issues.apache.org/jira/browse/MJAVADOC-656
> Project: Maven Javadoc Plugin (Moved to GitHub Issues)
> 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.
