Publish source jar when reading external .gradle file - gradle

Question

I have a git submodule (of which I have no control of) in my project which contains file named publish.gradle. The contents of this file are:
apply plugin: 'com.jfrog.artifactory'
apply plugin: 'maven-publish'
version = System.getenv()['VERSION'] ?: version
publishing {
publications {
mavenJava(MavenPublication) {
from components.java
}
}
}
artifactory {
contextUrl = repoBaseUrl
publish {
String publishRepoKey = version.endsWith('SNAPSHOT') ? repoKeySnapshot : repoKeyRelease
repository {
repoKey = publishRepoKey // The Artifactory repository key to publish to
username = System.getenv()['ARTIFACTORY_USERNAME'] ?: artifactoryUser // The publisher user name
password = System.getenv()['ARTIFACTORY_PASSWORD'] ?: artifactoryPassword // The publisher password
}
defaults {
publications('mavenJava')
publishArtifacts = true
publishPom = true
}
}
resolve {
repoKey = repoKey
}
}
In my build.gradle file I have the following line:
apply from: "${rootDir}/submodule/gradle/publish.gradle"
When I try to add the following line after this line:
task sourceJar(type: Jar) {
from sourceSets.main.allJava
}
publishing.publications.mavenJava.artifact sourceJar {
classifier 'sources'
}
Then the correct things get published, except that the pom file in the repository only contains a <dependencyManagement/> section and all the dependencies are missing. When I remove the above lines from build.gradle the pom is correct.

Answer 1

Try to override the all publishing block with :
publishing {
publications {
mavenJava(MavenPublication) {
from components.java
artifact sourceJar {
classifier "sources"
}
}
}
}
