-------------------------------------------
Summary: Taglet auto-detection doesn't support transitive
dependencies
Key: MJAVADOC-745
URL: https://issues.apache.org/jira/browse/MJAVADOC-745
Project: Maven Javadoc Plugin
Issue Type: Bug
Components: javadoc
Affects Versions: 3.4.1
Reporter: Stefano Chizzolini
The current implementation of the taglet auto-detection algorithm (initial
feature request: MJAVADOC-204) doesn't honor the transitive dependency
resolution of the 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]
and
[JavadocUtil.getTagletClassNames(..)|https://github.com/apache/maven-javadoc-plugin/blob/a5db96e7e16cc432d8fdea05f460f6c3fa258ba9/src/main/java/org/apache/maven/plugins/javadoc/JavadocUtil.java#L721]),
_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).
