Generate JavaDocs with Android Gradle plugin

For Android gradle plugin 1.1.2+ (com.android.tools.build:gradle:1.1.2+)

libraryVariants - does not work anymore

use:

task javadoc(type: Javadoc) {    source = android.sourceSets.main.java.srcDirs    classpath += project.files(android.getBootClasspath().join(File.pathSeparator))    destinationDir = file("../javadoc/")    failOnError false}

destinationDir = file("../javadoc/") - locate javadocs at root of project directory (in this way jenkins javadoc plugin could find it and show in special Document panel)

failOnError false - for suppress warnings that can cause fail build on jenkins

Gradle 1.11 - Gradle Plugin 0.10.0

Replace android.plugin.sdkDirectory by android.sdkDirectory

android.libraryVariants.all { variant ->    task("generate${variant.name}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.links("http://docs.oracle.com/javase/7/docs/api/");        options.links("http://d.android.com/reference/");        exclude '**/BuildConfig.java'        exclude '**/R.java'    }}

The solution I ended up settling on is as follows:

android.libraryVariants.all { variant ->    task("generate${variant.name}Javadoc", type: Javadoc) {        description "Generates Javadoc for $variant.name."        source = variant.javaCompile.source        ext.androidJar = "${android.plugin.sdkDirectory}/platforms/${android.compileSdkVersion}/android.jar"        classpath = files(variant.javaCompile.classpath.files) + files(ext.androidJar)    }}

Xavier Ducrohet confirmed this is the way to do it (with caveats) on the adt-dev group, https://groups.google.com/forum/#!searchin/adt-dev/javadoc/adt-dev/seRizEn8ICA/bafEvUl6mzsJ.
