Similar issue on Jenkins 2.164.3, Repository Connector 1.2.5, Nexus OSS 3.6.0-02. First of all I couldn't configure "Nexus Repository Manager Servers" (com.sonatype.nexus.api.zz.ey: Not Found), and in via Artifact Resolver: Repositories configuration (URL: https://my-nexus.com/repository/MyProjectSnapshots/, Repo type: hosted, Repo Id: MyProjectSnapshots) leads to:
16:18:55 INFO: define repo: [Repository id=MyProjectSnapshots, type=hosted, url=my-nexus.com/repository/MyProjectSnapshots, isRepositoryManager=false]16:18:55 INFO: set authentication for jenkins.user*16:18:55* failed collecting dependency info for [Artifact com.foo.my:android-apps:::0.1-SNAPSHOT]
Caused by: org.sonatype.aether.transfer.NoRepositoryConnectorException: No connector available to access repository MyProjectSnapshots (my-nexus.com/repository/MyProjectSnapshots) of type hosted using the available factories WagonRepositoryConnectorFactory
artifactResolver artifacts: [artifact(artifactId: 'android-apps', classifier: '', extension: '', groupId: 'com.foo.my',
targetFileName: '', version: '0.1-SNAPSHOT')], releaseChecksumPolicy: 'ignore', snapshotChecksumPolicy: 'ignore', targetDirectory: '.'
In addition to I've tried different configurations: with\without extension, different URL format (with\without application port), with\without POM file, etc.
For the record I've uploaded maven-artifacts by means of nexusArtifactUploader plugin, I could not find a way how to upload artifacts via Artifact Resolver but documentation says it has such feature.
