Stefano Chizzolini updated MJAVADOC-745:
----------------------------------------
Description: The current implementation of taglet auto-detection algorithm
(initial feature request: MJAVADOC-204) lacks proper evaluation of the
dependency tree of configured taglet artifacts (see
[<tagletArtifacts/>|https://maven.apache.org/plugins/maven-javadoc-plugin/javadoc-mojo.html#tagletArtifacts]):
_each artifact on the taglet classpath is scanned separately_ (see
[AbstractJavadocMojo.addTagletsFromTagletArtifacts(..)|https://github.com/apache/maven-javadoc-plugin/blob/a5db96e7e16cc432d8fdea05f460f6c3fa258ba9/src/main/java/org/apache/maven/plugins/javadoc/AbstractJavadocMojo.java#L5901]

_causing taglet class loading to fail in case its hierarchy is spread across
multiple artifacts_ (its class loader has visibility only on a single artifact
at a time, in the wrong assumption that no intermediate artifact lies between
the Taglet interface and its implementations). (was: The current
