Error Log :

[ERROR]BUILD ERROR
------------------------------------------------------------------------
Error building POM (may not be this project's POM).


Project ID: org.apache.maven.plugins:maven-resources-plugin

Reason: POM 'org.apache.maven.plugins:maven-resources-plugin' not found in repository: Unable to download the artifact from any repository

  org.apache.maven.plugins:maven-resources-plugin:pom:2.3

from the specified remote repositories:
  central (http://repo1.maven.org/maven2),
  unknown-jars-temp-repo (file:C:\Documents and Settings\Administrator\Desktop\taher\demomodel/lib),
  hibernate-support (http://download.java.net/maven/2)

 for project org.apache.maven.plugins:maven-resources-plugin

Answer 1

The problem could be due to bad (e.g. corrupted) metadata (because the maven-resources-plugin is definitely available in the central repository).

I suggest to delete ~/.m2/respository/org/apache/maven/plugins/maven-resources-plugin/ and to try again.

By the way, you don't need to declare (you have it by default):

<pluginRepository>
    <id>maven-repo</id>
    <name>Maven repo</name>
    <url>http://repo1.maven.org/maven2&lt;/url&gt;
</pluginRepository>
