I use nexus opensource version maven 2.2.1
When I type "mvn help:effective-settings", i got the error below
[INFO] Scanning for projects...
[INFO] Searching repository for plugin with prefix: '
help'.
[INFO] ------------------------------------------------------------------------
[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------
[INFO] Error building POM (may not be this project's POM).
Project ID: org.apache.maven.plugins:maven-help-plugin
Reason: Error getting POM for 'org.apache.maven.plugins:maven-help-plugin' from the repository: Failed to resolve artifact, possibly due to a repository list that is not appropriately equipped for this artifact's metadata.
org.apache.maven.plugins:maven-help-plugin:pom:2.2-SNAPSHOT
from the specified remote repositories:
Nexus (http://192.168.56.191:8081/nexus/content/groups/public)
for project org.apache.maven.plugins:maven-help-plugin
When I check the local repository under ~.m2\repository\org\apache\maven\plugins\maven-help-plugin
It has a file maven-metadata-central.xml
<?xml version="1.0" encoding="UTF-8"?>
<metadata>
<groupId>org.apache.maven.plugins</groupId>

And I can't find any jar files under directory, what's wrong with nexus server ? I can't easily find support information from nexus.
Any hints
