Gradle artifactoryPublish won't deploy .jar file generated by spring boot

Question

I'm trying to deploy a jar + pom file to artifactory using gradle + artifactory plugin + maven-publish plugin.

I've tried multiple solutions from other sources like this and I think the spring-boot plugin is breaking stuff (because it edits the jar file)

The following script successfully uploads a .pom file, but not the .jar file generated by spring-boot. How can I get it to also upload that?

this is my build.gradle:

buildscript {
    ext {
        springBootVersion = '1.4.0.RELEASE'
    }
    repositories {
        mavenCentral()
        jcenter()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
        classpath "org.jfrog.buildinfo:build-info-extractor-gradle:4.4.0"
    }
}
apply plugin: 'java'
apply plugin: 'spring-boot'
apply plugin: "com.jfrog.artifactory"
apply plugin: 'maven-publish'
apply from: "gradle/artifactory.gradle"

publishing {
    publications {
        mavenJava(MavenPublication) {
            components.java
        }
    }
}

jar {
    baseName = 'BatchParser'

}

version = '1.0'
sourceCompatibility = 1.8
targetCompatibility = 1.8

repositories {
    mavenCentral()
}


dependencies {

    compile('org.projectlombok:lombok:1.16.10')
    ...
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

and artifactory.gradle

artifactory {
    contextUrl = 'url'
    publish {
        repository {
            repoKey = 'libs-release-local'
            username = 'user'
            password = 'password'
        }
        defaults {
            publications("mavenJava")
        }
    }
}

output of:

gradlew clean build artifactoryPublish

There's a very subtle mistake in your publishing block. from is missing which is causing Gradle to silently not include the jar file in the publication. You need to update your publishing block so that it looks like this:

publications {
    mavenJava(MavenPublication) {
        from components.java
    }
}

If I were you, I'd open a Gradle usability bug for this. Silently doing nothing isn't very user friendly.
