[Gradle] Cannot publish pom for project ':' since it does not contain the Maven plugin install task and task ':artifactoryPublish' does not specify a custom pom path.

Running any Gradle task triggers lots of Cannot publish pom for project ':' since it does not contain the Maven plugin install task and task ':artifactoryPublish' does not specify a custom pom path. messages.

Example build.gradle to reproduce:

plugins {
  id 'java-gradle-plugin'
  id 'groovy'
  id 'maven-publish'
  id 'com.jfrog.artifactory' version '4.13.0'
}

group = "com.example.artifactory.gradle.test"
version = "1.2.3.9"

dependencies {
  implementation gradleApi()
  implementation localGroovy()
  implementation "com.google.guava:guava:28.2-jre"
}

gradlePlugin {
  plugins {
    simplePlugin {
      id = 'com.example.artifactory.gradle.test'
      implementationClass = 'com.example.artifactory.gradle.test.TestPlugin'
    }
  }
}

artifactory {
  contextUrl = "${artifactory_contextUrl}"
  publish {
    repository {
      repoKey = 'publish-test'
      username = artifactory_user
      password = artifactory_password
      maven = true
    }
    defaults {
      // this is needed because some of our project produce no artifacts but have dependencies (in lots of different custom configurations)
      configurations.each { conf ->
        if (conf.canBeResolved) publishConfigs(conf.name)
      }
      // this is needed because otherwise the artifactory plugin does _NOTHING_ publishToMavenLocal works just fine...
      project.publishing.publications.each { pub ->
        publications(pub.name)
      }
      publishPom = true
    }
  }
  resolve {
    repository {
      repoKey = 'dependencies'
      username = artifactory_user
      password = artifactory_password
      maven = true
    }
  }

Expected behavior:

• I expect that such a simple project (in terms of build.gradle setup of artifacts and dependencies) automatically publishes all artifacts, that publishToMavenLocal would publish, to artifactory.
• I expect that all dependencies of the build are listed in the build info of such a build (running with Jenkins) also of subprojects that have no artifacts! -> see also inline comments above
• and while we are at this: why are the build dependencies not published in the build infos? having bad jars on the build classpath is also something I would want to get notified by Xray.

So far it seems to be impossible to publish all artifacts and have all dependencies in the build-info without also having MEGABYTES of the warning above in the build logs (our actual builds have many more subprojects obviously)

Anyone found answer?

I’m using Gradle 6.9. Plugin version 4.29.0. Single project.

plugins {
    id 'war'
    id 'maven-publish'
    id 'com.jfrog.artifactory' version '4.29.0'
}

// Let me know if you want more sections of my build.gradle

publishing {
    publications {
        maven(MavenPublication) {
            from components.web
            artifact createTar
        }
    }
}

artifactory {
    contextUrl = 'http://artifactory.mycorp.com/artifactory'
    publish {
        repository {
            repoKey = version.endsWith('SNAPSHOT') ? "twd-maven-snapshot-local-dev" : "twd-maven-local-dev"
            username = System.getenv('PUBLISH_USERNAME')
            password = System.getenv('PUBLISH_PASSWORD')
        }
        defaults {
            publications('ALL_PUBLICATIONS')
            publishConfigs('archives', 'published')
            properties = [
                    'build.branch': System.getenv('CI_COMMIT_BRANCH'),
                    'build.key': "${artifactId}-${System.getenv('CI_PIPELINE_ID')}"
            ]
        }
        publishBuildInfo = false   // FIXME - remove after RITM0074898 is fixed
        publishArtifacts = true
        publishPom = true
        publishIvy = false
    }
}

It does appear to be publishing the pom (see below). Maybe the error is spurious?

$ dotenv run gradle artifactoryPublish
