Reproduction:

• fresh jenkins install via docker
• Install/configure with bare minimum to use v2.0 of this plugin
• Create simple pipeline job to build this plugin

See attached screen shot for results.  Jenkins does not recognize the fingerprint of the artifacts.

Pipeline script is as follows:

node() {
  git 'git@github.com:my-fork/pipeline-maven-plugin.git'
  withMaven(maven: 'M3') {
    sh "mvn clean install"
  }
}
