Take a look at: http://stackoverflow.com/questions/1751987/disable-maven-scm

What's in your pom.xml file ?

It is not clear what goal you are executing but the error looks self explaining: you need to add a SCM element:

<project xmlns="http://maven.apache.org/POM/4.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
                      http://maven.apache.org/xsd/maven-4.0.0.xsd"&gt;
  ...
  <scm>
    <connection>scm:svn:http://127.0.0.1/svn/my-project&lt;/connection&gt;
    <developerConnection>scm:svn:https://127.0.0.1/svn/my-project&lt;/developerConnection&gt;
    <tag>HEAD</tag>
    <url>http://127.0.0.1/websvn/my-project&lt;/url&gt;
  </scm>
  ...
</project>

The problem could be due to a missing developerConnection in the SCM section of your POM. This can lead to the (misleading) error message you are reporting: http://jira.codehaus.org/browse/MOJO-1014

It would help if you could post a copy of your POM and the goal you are trying to execute.
