Hello,
I've tried searching for this problem on Google but so far have not had any
luck locating this exact error so I wanted to see if anyone on the mailing can
help out. I have Maven 2.0.4 installed and I am trying to use the Hibernate3
plugin. I added the repositories configuration to my pom.xml:
<repositories>
<repository>
<id>Maven Snapshots</id>
<url>http://snapshots.maven.codehaus.org/maven2/</url>
<snapshots>
<enabled>true</enabled>
</snapshots>
<releases>
<enabled>false</enabled>
</releases>
</repository>
</repositories>
<pluginRepositories>
<pluginRepository>
<id>Maven Snapshots</id>
<url>http://snapshots.maven.codehaus.org/maven2/</url>
<snapshots>
<enabled>true</enabled>
</snapshots>
<releases>
<enabled>false</enabled>
</releases>
</pluginRepository>
</pluginRepositories>
and was able to download the required plugin but it fails with the following
error:

Using the -X flag outputs more information but nothing seems to be obviously
wrong.
Has anyone successfully used the Hibernate3 plugin to generate a ddl? If so,
is there a magic step I should take or a best place to look for this problem?
Thanks,
James
