When my pom.xml contains above content and local repository has not parent pom, jenkins has following error:

but when I execute "mvn package" on the command line, it can download parent pom:
Downloading: http://cloudrepo.rd.test.net:8081/nexus/content/groups/public/com/test/cloud-parent/1.1.0/cloud-parent-1.1.0.pom
Downloaded: http://cloudrepo.rd.test.net:8081/nexus/content/groups/public/com/test/cloud-parent/1.1.0/cloud-parent-1.1.0.pom (16 KB at 34.7 KB/sec)

Jenkins can download the corresponding dependencies and build success when other dependencies are changed, so I don't think there is a problem with the configuration of jenkins.
