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:
