Plugin repository

build.gradle.kts

plugins {
  kotlin("jvm") version "1.9.22"
  id("me.qoomon.git-versioning") version "6.4.3"
  `maven-publish`
  `kotlin-dsl`

group = "io.github.benkeil"

gradlePlugin {
  website = "https://github.com/benkeil/openapi-dsl-gradle"
  vcsUrl = "https://github.com/benkeil/openapi-dsl-gradle.git"
  plugins {
    create("openapiDsl") {
      id = "io.github.benkeil.openapi-dsl-gradle"
      displayName = "OpenAPI Kotlin DSL Gradle Plugin"
      description =
          "Generates special kotlin classes from OpenAPI schemas, that can be used to build custom DSLs"
      tags = listOf("openapi", "dsl", "kotlin")
      implementationClass = "pub.keil.openapi.dsl.plugin.OpenapiDslPlugin"
    }
  }
}

publishing {
  repositories {
    mavenLocal()
    maven {
      name = "GitHubPackages"
      url = uri("https://maven.pkg.github.com/benkeil/${rootProject.name}")
      credentials {
        username = "not_required"
        password = System.getenv("GITHUB_PACKAGES_WRITE_TOKEN")
      }
    }
  }

  publications { register<MavenPublication>("gpr") { from(components["java"]) } }
}

I publish to GitHub (or mavenLocal) and not publishPlugin.

When trying to build I get:
