Enhance javadoc generation for specific Java project

Help/Discuss
1

I would like to enhance the javadoc task to generate additional javadoc entries based on annotations specific to my Java project. I have found a Java routine called Javadoc.java which looks interesting, but I thought tasks were written in C, and packaged as dlls. I am using Gradle-2.14.1.

My questions are: a) which module has to be modified to do this, and b) how do I get gradle build to pick up the modified module?

You can provide a custom doclet

configurations {
   mydoclet
}
dependencies {
   mydoclet project(':mydoclet')
}
javadoc {
   options.docletpath = configurations.mydoclet.files.asType(List)
   options.doclet = 'com.foo.MyDoclet'
}

https://docs.gradle.org/current/dsl/org.gradle.api.tasks.javadoc.Javadoc.html
http://docs.oracle.com/javase/7/docs/technotes/guides/javadoc/doclet/overview.html

Many thanks, @Lance_Java, that looks pretty clear and complete! Wish me luck!

Hi @Lance_Java (or anyone!), I have been struggling with this for a week now, and I apologize for being really dense. I think I need a Gradle for Dummies book!

I have stitched together a build.gradle from various sources (like StackOverflow), which I have used successfully to upload my project to Maven. I have a folder called mydoclet in my root folder (javafbp). When I tried adding the following, as per your suggestions, plus project, which is probably wrong :slight_smile: :

configurations {
   mydoclet
}
dependencies {
  mydoclet project(':mydoclet')
}

//task listComponentAttributes(type: Javadoc) {
javadoc {
  source = sourceSets.main.allJava
  destinationDir = reporting.file("build/docs/compattrs.txt")
  options.docletpath = configurations.mydoclet.files.asType(List)
  options.doclet = "ListClass "
}
   
project(':mydoclet') {
    task listComponentAttributes
}

I got this message:

> Could not get unknown property 'javadoc' for task ':mydoclet:javadocJar' of type org.gradle.api.tasks.bundling.Jar.

Some responses to queries seem to suggest I need a settings.gradle file - I created one saying include(':mydoclet')

Obviously I am missing some key concepts, but I find the Gradle documentation really confusing!

Here is my build.gradle - probably completely wrong! Also pls excuse lack of formatting! Help would be much appreciated! TIA
