How to push maven to OSSRH from previous local publish

Help/Discuss
1

Hey everyone.

I have a GitHub actions pipeline where I want to do following in multiple separate jobs:

[Build] → [Test] → [Publish]

In the Build job I publish my library via publishMavenJavaToDistPathRepository into a local maven folder which is then packaged as build artifacts

In the Test job I have a separate project consuming the artifacts and integrating my library from Maven using this path.

The Publish job shoudl then upload the libraries if successful.

But how can I now do a publish of all my files from the and packages to Sonatype OSSRH?
I have a multi-project setup and configure things like here:

// loaded from environment and props files 
var sonatypeSigningKeyId = ""
var sonatypeSigningPassword = ""
var sonatypeSigningKey = ""
var ossrhUsername = ""
var ossrhPassword = ""
var sonatypeStagingProfileId = ""

var libDescription = ""
var libAuthorId = ""
var libAuthorName = ""
var libOrgUrl = ""
var libCompany = ""
var libVersion = ""
var libProjectUrl = ""
var libGitUrlHttp = ""
var libGitUrlGit = ""
var libLicenseSpdx = ""
var libLicenseUrl = ""
var libIssuesUrl = ""

// configuring 
subprojects {
    apply<JavaLibraryPlugin>()
    apply<MavenPublishPlugin>()
    apply(plugin = "maven-publish")
    apply(plugin = "signing")

    group = "net.alphatab"
    version = libVersion

    repositories {
        google()
        mavenCentral()
    }

    configure<JavaPluginExtension> {
        toolchain {
            languageVersion.set(JavaLanguageVersion.of(17))
        }
        withSourcesJar()
        withJavadocJar()
    } 

    configure<SigningExtension> {
        if (sonatypeSigningKeyId.isNotBlank() && sonatypeSigningKey.isNotBlank() && sonatypeSigningPassword.isNotBlank()) {
            useInMemoryPgpKeys(sonatypeSigningKeyId, sonatypeSigningKey, sonatypeSigningPassword)
            sign(extensions.getByType<PublishingExtension>().publications["mavenJava"])
        }
    }

    configure<PublishingExtension> {
        repositories {
            maven {
                name = "sonatype"
                url = uri(
                    if (version.toString().endsWith("SNAPSHOT"))
                        "https://s01.oss.sonatype.org/content/repositories/snapshots/"
                    else
                        "https://s01.oss.sonatype.org/service/local/staging/deploy/maven2/"
                )
                credentials {
                    username = ossrhUsername
                    password = ossrhPassword
                }
            }

            maven {
                name = "DistPath"
                url = rootProject.projectDir.resolve("dist").toURI()
            }
        }

        publications {
            // this publication builds the library and is meant to publish to the local dist folder
            create<MavenPublication>("mavenJava") {
                from(components["java"])
                afterEvaluate {
                    artifactId = tasks.withType<Jar>().first().archiveBaseName.get()
                    pom {
                        description = libDescription
                        url = libProjectUrl
                        licenses {
                            license {
                                name = libLicenseSpdx
                                url = libLicenseUrl
                            }
                        }
                        developers {
                            developer {
                                id = libAuthorId
                                name = libAuthorName
                                organization = libCompany
                                organizationUrl = libOrgUrl
                            }
                        }
                        scm {
                            url = libGitUrlHttp
                            connection = "scm:git:$libGitUrlGit"
                            developerConnection = "scm:git:$libGitUrlGit"
                        }
                        issueManagement {
                            system = "GitHub"
                            url = libIssuesUrl
                        }
                    }
                }
            }
        }
    }
}

Is it maybe somehow possible to create a publication “MavenDist” from the files in the previously published dist folder and the callpublishMavenDistToSonatypeRepository? How would such a with keeping all metadata and details look like in Gradle?

Or is there a good alternative to mvn deploy:deploy-filein the maven-publish plugin I could use?

Thanks
