Subject Error using the release:prepare goal
Date Fri, 01 Sep 2006 21:58:57 GMT
Hi,

I was trying to test the plugin maven-release, and got a
NullPointerException while executing the prepare goal. I've used a
project created with the archetype:create goal, and the only
modifications I have made were to set the properties needed by the
release plugin in the pom.xml:


<scm>
    <developerConnection>scm:svn:http://myhost/svn/myproject/trunk</developerConnection>
</scm>

and

<build>
    <plugins>
      <plugin>
        <artifactId>maven-release-plugin</artifactId>
        <configuration>
          <tagBase>
            http://myhost/svn/myproject/tags
          </tagBase>
        </configuration>
      </plugin>
    </plugins>
</build>

After that, I've run "mvn release:prepare" from the command line, and
Maven has thrown this stack trace:
