Upload artifact to Artifactory using Gradle

You need plugins :

apply plugin: 'java'
apply plugin: 'groovy'
apply plugin: 'maven'
apply plugin: 'maven-publish'
apply plugin: 'com.jfrog.artifactory'

to build project and retrieve jars from artifactory:

buildscript {
    repositories {
        maven {
            url 'http://[IP]:[PORT]/artifactory/gradle-dev'
            credentials {
                username = "${artifactory_user}"
                password = "${artifactory_password}"
            }
        }
        mavenCentral()
    }
    dependencies { classpath "org.jfrog.buildinfo:build-info-extractor-gradle:4.5.4" }
}

repositories {
    mavenCentral()
    mavenLocal()
}

Artifactory configs:

artifactory {
    contextUrl = "${artifactory_contextUrl}"
    publish {
        repository {
            repoKey = 'gradle-dev-local'
            username = "${artifactory_user}"
            password = "${artifactory_password}"
            maven = true
        }
        defaults {
            publications('mavenJava')
        }
        publishBuildInfo = true
        publishArtifacts = true
        publishPom = true
    }
    resolve {
        repository {
            repoKey = 'gradle-dev'
            username = "${artifactory_user}"
            password = "${artifactory_password}"
            maven = true

        }
    }
}

and for publishing:

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

gradle.properties

artifactory_user=publisher
artifactory_password=*****
artifactory_contextUrl=http://IP:PORT/artifactory

So everything is just simple. If you want to upload your jar:

gradle artifactoryPublish

That's because you don't have any publications. The artifactory-publish plugin works with maven-publish plugin and uploads publications.

If you prefer working with the old maven plugin, you need artifactory plugin, not artifactory-publish.

Take a look at the Overview part in "Working with Gradle" page of the official docs.

I got this working. I was actually using an already created jar so I am using the below code to specify my jar that is to be uploaded:

publishing {
    publications {
        mavenJava(MavenPublication) {
            // from components.java
            artifact file("path/jar-1.0.0.jar")
        }
    }
}
