gradle publishing multi module project to AWS Artifact only publishes META-INF - scala

Question

I recently started using gradle and trying to publish a multi module project to AWS Artifact. My build file for submodules looks like below
Module: core
buildscript {
dependencies {
classpath "org.jsonschema2pojo:jsonschema2pojo-gradle-plugin:0.4.34"
}
}
plugins {
id "net.researchgate.release" version "2.8.0"
}
group "com.local"
apply plugin: "java"
apply plugin: "jsonschema2pojo"
apply plugin: "maven"
apply plugin: "net.researchgate.release"
jar {
baseName "core-schema"
}
release {
tagTemplate = 'core-${version}'
}
jsonSchema2Pojo {
source files("${projectDir}/src/main/resources/json")
generateBuilders = true
}
dependencies {
compile 'commons-lang:commons-lang:2.6'
compile 'javax.validation:validation-api:2.0.0.Final'
compile 'com.fasterxml.jackson.core:jackson-databind:2.9.9'
compile 'com.fasterxml.jackson.core:jackson-annotations:2.9.9'
}
afterReleaseBuild.dependsOn uploadArchives
spark-example
plugins {
id 'java'
id 'java-library'
id 'scala'
id 'com.github.johnrengelman.shadow' version '1.2.4'
}
apply plugin: 'scalaStyle'
scalaStyle {
configLocation = "${project.rootDir}/scalastyle_config.xml"
includeTestSourceDirectory = true
source = "src/main/scala"
testSource = "src/test/scala"
}
dependencies {
compile group: 'org.apache.spark', name: "spark-core_2.11", version: '2.4.2'
compile group: 'org.apache.spark', name: "spark-sql_2.11", version: '2.4.2'
}
configurations {
runtime.exclude module: 'spark-core_2.11'
runtime.exclude module: 'spark-sql_2.11'
}
compileScala.dependsOn(scalaStyle)
jar {
mainClassName = 'NONE'
baseName "spark-sample"
}
tasks.withType(ScalaCompile) {
ScalaCompileOptions.metaClass.daemonServer = true
ScalaCompileOptions.metaClass.fork = true
ScalaCompileOptions.metaClass.useAnt = false
ScalaCompileOptions.metaClass.useCompileDaemon = false
}
tasks.withType(ScalaCompile) {
configure(scalaCompileOptions.forkOptions) {
memoryMaximumSize = '1g'
jvmArgs = ['-XX:MaxPermSize=512m']
}
}
And main application build file looks like below:
plugins {
id 'java-library'
id 'maven-publish'
}
group "com.local"
subprojects { subproject ->
configurations {
deployer
}
dependencies {
deployer 'org.kuali.maven.wagons:maven-s3-wagon:1.2.1'
}
repositories {
mavenCentral()
mavenLocal()
jcenter()
maven {
url "${aws_url}"
credentials {
username "aws"
password System.env.CODEARTIFACT_AUTH_TOKEN
}
}
}
}
publishing {
publications {
mavenJava(MavenPublication) {
groupId = group
artifactId = artifactName
version = version
from components.java
}
}
repositories {
maven {
url "${aws_url}"
credentials {
username "aws"
password System.env.CODEARTIFACT_AUTH_TOKEN
}
}
}
}
now when I run gradle build I can see jars getting created for all the modules and root project under corresponding build/libs/ directory with code files. However when I do gradle publish I only see root jar getting published with only MANIFEST.NF file as shown below:
Update:
As suggested by #nico I have tried adding the publishing block in allprojects{} block but it is publishing each project with the root project name and overriding all of them as seen in below log. I have also tried adding the publishing block in subproject like mentioned in this post but still same output.
2030009268:spark-store user$ gradle publishAllPublicationsToMavenRepository
> Task :core:publishMavenJavaPublicationToMavenRepository
Multiple publications with coordinates 'com.local:spark-sample:0.0.5-SNAPSHOT' are published to repository 'maven'. The publications will overwrite each other!
> Task :spark-sample:publishMavenJavaPublicationToMavenRepository
Multiple publications with coordinates 'com.local:spark-sample:0.0.5-SNAPSHOT' are published to repository 'maven'. The publications will overwrite each other!
Multiple publications with coordinates 'com.local:spark-sample:0.0.5-SNAPSHOT' are published to repository 'maven'. The publications will overwrite each other!
Updated root project build:
plugins {
id 'java-library'
id 'maven-publish'
}
group "com.local"
subprojects { subproject ->
configurations {
deployer
}
dependencies {
deployer 'org.kuali.maven.wagons:maven-s3-wagon:1.2.1'
}
repositories {
mavenCentral()
mavenLocal()
jcenter()
maven {
url "${aws_url}"
credentials {
username "aws"
password System.env.CODEARTIFACT_AUTH_TOKEN
}
}
}
}
allprojects {
apply plugin: 'maven-publish'
apply plugin: 'java-library'
publishing {
publications {
mavenJava(MavenPublication) {
groupId = group
artifactId = artifactName
version = version
from components.java
}
}
repositories {
maven {
url "${aws_url}"
credentials {
username "aws"
password System.env.CODEARTIFACT_AUTH_TOKEN
}
}
}
}
}

Regarding your main application build file:
Try including the publishing{} block inside of an allprojects{} block or add it to the above subprojects{} block as well. Currently the publishing-specification is only applied on root-project level.
