Publish to Sonatype using NEW gradle plugin: maven-publish

Question

So far I am uploading java artifacts to Sonar Nexus using the Gradle upload task; for example: https://github.com/oblac/jodd/blob/master/gradle/publish-maven.gradle

Recently I noticed that Gradle has new plugin maven-publish. I wanted to use it, as it seems it is going to be the main one for publishing. However, I am not being able to upload it to Nexus. So far, my file looks like this:

repositories {
    mavenCentral()
    jcenter()
}

apply plugin: 'java'
apply plugin: 'maven-publish'

group = 'com.foo'
version = 1.0

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {
    compile "...."
}

task sourceJar(type: Jar) {
    classifier = 'sources'
    from sourceSets.main.allJava
}
javadoc {
    failOnError = false
}
task javadocJar(type: Jar, dependsOn: javadoc) {
    classifier = 'javadoc'
    from javadoc.destinationDir
}
publishing {
    publications {
        mavenJava(MavenPublication) {
            from components.java

            artifact sourceJar
            artifact javadocJar
        }
    }
    repositories {
        maven {
            url "https://oss.sonatype.org/service/local/staging/deploy/maven2"
        }
    }
}

task wrapper(type: Wrapper) {
    gradleVersion = '3.4.1'
}

I guess I am missing something? I know I am missing signing, but that is not relevant for uploading. I am not being able to upload artifact using gradle publish.

Current error is:

Could not transfer artifact XXX from/to remote (https://oss.sonatype.org/service/local/staging/deploy/maven2): Could not write to resource 'XXX'.

I think you miss the authentication information and thus do not have the right to release to Sonatype OSS, as you try to deploy anonymously.
