<h2>hibernate-maven-plugin always needs a database-connection</h2>
<p>
- The default-configuration uses the EXPORT-target of the SchemaExport-Tool.
- If you do not need to create a database with the evaluated schema, you can
- use the NONE- or the SCRIPT-target.
+ The default-configuration exports the created schema to the configured
+ database.
+ Therefore, it needs a valid database-connection and fails, if none is
+ available.
+ If you do not need to export the created schema to a database,
+ you can set the property <code>hibernate.schema.export</code> to
+ <code>false</code>.
This can be achieved with the command-line parameter
- <code>-Dhibernate.export.target=SCRIPT</code> or with the following configuration:
+ <code>-Dhibernate.schema.export=false</code> or with the following
+ configuration:

<pre class="prettyprint linenums lang-html">
<configuration>
- <target>SCRIPT</target>
+ <export>false</export>
</configuration></pre>
<p>
But even when no database is to be created, hibernate always needs to know
- the dialect. Hence, the plugin will fail if this parameter is missing!

To circumvent this problem, hibernate-maven-plugin signals a skipped
- excecution by setting the maven property <code>$\{hibernate.export.skipped\}</code> to
+ excecution by setting the maven property <code>${hibernate.schema.skipped}</code> to
<code>true</code>.
You can configure other plugins to react on this signal.
For example, the dbunit-plugin can be configured to skip its excecution, if
<groupId>org.codehaus.mojo</groupId>
<artifactId>dbunit-maven-plugin</artifactId>
<configuration>
- <skip>${hibernate.export.skipped}</skip>
+ <skip>${hibernate.schema.skipped}</skip>
</configuration>
