javadoc-plugin error since plugin-pom 4.19 ?

[Goyot, Martin]

Hi there,

We repeatedly run into an error trying to `maven release:prepare release:perform` our plugin. It would appear that the javadoc plugin was updated by plugin-pom 4.19 but maybe this is just a misguided guess. Someone with the same kind of error ?

here is the trace:

There appears to be a problem in the Javadoc generation process for Jenkins core.  When I open https://javadoc.jenkins-ci.org/ , it shows 3 links (as expected).  When I click the "plugins" link and the "components" link, it opens a page listing those items.  When I click the "Jenkins core" link, it reports "404 - not found".

Will need some further research to understand why that Javadoc page is not being generated for Jenkins core.

If you need to release in a hurry, you could generate the javadoc without the reference to https://javadoc.jenkins.io/ by adding the following into the builds section of your pom file:

        <plugins>

            <plugin>

                <artifactId>maven-javadoc-plugin</artifactId>

                <version>3.3.0</version>

                <configuration combine.self="override">

                    <source>8</source>

                    <quiet>false</quiet>

                    <links></links>

                </configuration>

            </plugin>

        </plugins>

Looks like it's a side effect of the 2.300 release not being in the usual repo (see my thread from last week). If so, it should resolve itself later today with the release of 2.301.

Thanks Daniel!

When it is resolved, we can close https://issues.jenkins.io/browse/WEBSITE-779 that reports the issue in the issue tracker.

https://github.com/jenkins-infra/javadoc/pull/30 ought to prevent a recurrence.
