Gradle workflows

[GoogleCodeExporter]

The following gradle configuration is not working

configurations {
    jaxDoclet
}

android.libraryVariants.all { variant ->
    task("generate${variant.name.capitalize()}Javadoc", type: Javadoc) {
        description "Generates Javadoc for $variant.name."
        source = variant.javaCompile.source
        ext.androidJar = "${android.sdkDirectory}/platforms/${android.compileSdkVersion}/android.jar"
        classpath = files(variant.javaCompile.classpath.files) + files(ext.androidJar)
        options.docletpath = configurations.jaxDoclet.files.asType(List)
        exclude '**/BuildConfig.java'
        exclude '**/R.java'

        options {
            doclet "com.google.doclava.Doclava"
            bootClasspath new File(System.getenv('JAVA_HOME') + "/jre/lib/rt.jar")
            addStringOption "hdf project.name", project.name
            addStringOption "federate android", "http://d.android.com/reference"
        }
    }
}

dependencies {
    jaxDoclet 'com.google.doclava:doclava:1.0.6'
}

What steps will reproduce the problem?
1. Add above to android library module gradle build
2. Run the javadoc task  --debug or -- stacktrace
3. See the error log output

What is the expected output? What do you see instead?
I expect the javadoc to be generated using the doclava doclet.  I see no 
javadoc html files generated.

Is there support for using gradle with doclava?  If so, what am I doing wrong?  
The error output is not very helpful and the javadoc.options file seems to pick 
up all the correct dependencies to build.  I can generate javadoc without 
doclava so the variant is working when doclava is removed.
