build.gradle - How to generate multiple jar files with gradle's java plugin -

i have multi-project gradle build using java plugin setup follows:

myproj/   settings.gradle   build.gradle   util/     build.gradle 

in util project, generate 2 jars... 1 packagea , 1 packageb. i'm noob gradle here appreciated. here settings , gradle files:

myproj/settings.gradle

include 'util' 

myproj/build.gradle

subprojects {     apply plugin: 'java'      repositories {         maven {             url "http://mymavenurl"         }     }      sourcesets {         main {             java {                 srcdir 'src/java'             }         }     } } 

myproj/util/build.gradle

dependencies {     .     .     . } jar {     basename = 'packagea'     includes = ['com/mycomp/packagea'] } task packagebjar(type: jar) {     dependson classes     includes = ['com/mycomp/packageb']     basename = 'packageb' } 

when try build project here output:

:util:compilejava :util:processresources up-to-date :util:classes :util:jar :util:assemble :util:compiletestjava up-to-date :util:processtestresources up-to-date :util:testclasses up-to-date :util:test :util:check :util:build 

i hope see :util:packagebjar after classes, i'm not having luck.

one way declare packagebjar artifact of, say, archives configuration:

artifacts {     archives packagebjar } 

now gradle assemble, , therefore gradle build, produce packagebjar.
