gradle adding -source.jar to war - gradle

Question

I am in the process of converting a number of projects from ant+ivy to Gradle.
One of the projects (address) produces a simple jar for inclusion into a webapp. I have set up the build.gradle to publish the jar and a sources jar to my private ivy repository.
address/build.gradle excerpt:
apply plugin: 'java'
apply plugin: 'publishing'
apply plugin: 'ivy-publish'
[...snip...]
task sourceJar(type: Jar) {
from sourceSets.main.java
classifier "source"
}
publishing {
repositories {
ivy {
url 'http://dev.example.com/ivy/'
layout "pattern", {
artifact "[organisation]/[module]/[type]s/[artifact]-[revision].[ext]"
}
}
}
publications {
ivy(IvyPublication) {
from components.java
artifact(sourceJar) {
type "source"
}
}
}
}
I publish this with gradlew publish. My webapp then has a dependency on the resulting jar:
compile 'com.example:address:1.0.0'
The problem I have is that when I do gradlew build on the webapp, the war's WEB-INF/lib includes address-source-1.0.0.jar along with the expected address-1.0.0.jar.
I cannot figure out why the source jar is being included in the war. It does not show up in gradlew dependencies.
Here is the ivy.xml being generated for the jar:
<?xml version="1.0" encoding="UTF-8"?>
<ivy-module version="2.0" xmlns:m="http://ant.apache.org/ivy/maven">
<info organisation="com.example" module="address" revision="1.0.0" status="integration" publication="20141027154452"/>

</ivy-module>

Answer 1

I think the reason is that the source artifact is published in the runtime configuration as well, if you use a special configuration (e.g. sources) it should work:
publications {
ivyJava(IvyPublication) {
from components.java
configurations.create('sources')
artifact(sourceJar) {
conf "sources"
}
}
}
(configurations.create() is needed because of
GRADLE-3162)
