无法从Javadoc元素获取完全限定的类型名称

Question

Short and sweet: despite the fact that I am asking the Javadoc API to give me the fully-qualified name of an annotation, it is only returning the simple type name.

I am writing a Javadoc doclet that relies heavily on the inspection of annotations. As such, I have created a utility function that will take an array of AnnotationDesc objects and return a Map that associates the fully-qualified name of the annotation to the AnnotationDesc object that describes it. Here are the relevant functions:

public static final Map<String, AnnotationDesc> getAnnotationMap(AnnotationDesc[] notes)
{
    if (notes == null)
    {
        return Collections.emptyMap();
    }

    return Collections.unmodifiableMap(Arrays.stream(notes).collect(Collectors.toMap(AnnotationUtils::getNoteName, note -> note)));
}

private static String getNoteName(AnnotationDesc note) { return note.annotationType().qualifiedTypeName(); }

For what it's worth, I have also tried using qualifiedName , which is another method exposed by the return value of the AnnotationDesc.annotationType method.

In my integration tests, this is all working great. However, when I push my doclet out to Artifactory, pull it down into another project and try to invoke it by way of a Gradle task, the keys in my map are the simple type names of the annotations.

Here is the definition of my Gradle task:

task myDocletTask(type: Javadoc) {
    source = sourceSets.main.allJava
    destinationDir = reporting.file("my-doclet-dir")
    options.docletpath = configurations.jaxDoclet.files.asType(List)
    options.doclet = <redacted - fully qualified type name of custom doclet>
}

I have noticed that if a program element is annotated with a fully-qualified annotation, then the fully-qualified name is actually picked up by the Javadoc API. Eg: @com.package.Annotation results in the expected behavior, but @Annotation does not.

Can someone please help me to understand why this is happening and, more importantly, how I can achieve the expected/desired behavior?

The problem was that the annotations were not on the classpath of the doclet at "documentation time". In order to fix this problem I augmented my Gradle Javadoc task with the following line: options.classpath = sourceSets.main.runtimeClasspath.asType(List) .
