+ <h2>Configuration Through A Configuration-File</h2>
<p>
The most simple way to configure the plugin is, to put all the
- hibernate-configuration in a <strong>hibernate.properties</strong>-file on your
- classpath. Put the file in the <code>resources</code>-folder. Maven will put
- it in the <code>class</code>-folder of your webapp, where it will be picked up
- by this plugin as well as by Hibernate 4.
+ hibernate-configuration in a <strong>hibernate.properties</strong>- or
+ a <strong>hibernate.cfg.xml</strong>-file on your classpath or in the
+ <strong>persistence.xml</strong>-file of your JPA-configuration, just
+ like you would do, if you are not using the
+ <code>hibernate-maven-plugin</code>.
</p>
<p>
Doing so, the only additionally configuration needed, to activat the plugin
<executions>
<execution>
<goals>
- <goal>export</goal>
+ <goal>create</goal>
</goals>
</execution>
</executions>
</plugin></pre>
<p>
- But be aware, that in this case the database-url, that is
- build in the application is the same that is used while testing, where
- the database is droped and recreated by the plugin.
+ This would create the configured database.
+ If you want it to be droped beforehand, you have to add the goal
+ <code>drop</code>:
+ </p>
+ <pre class="prettyprint linenums lang-html">
+<plugin>
+ <groupId>de.juplo</groupId>
+ <artifactId>hibernate-maven-plugin</artifactId>
+ <version>${project.version}</version>
+ <executions>
+ <execution>
+ <goals>
+ <goal>drop</goal>
+ <goal>create</goal>
+ </goals>
+ </execution>
+ </executions>
+</plugin></pre>
+ <p>
+ A correspondin goal for the command <code>update</code> is missing in this
+ version, but we are planning to implement it in near feature.
+ </p>
+ <p>
+ In order to let this configuration work, your configuration file must
+ contain a complete valid configuration for the database, that you want
+ to use.
+ A simple example <code>hibernate.properties</code>-file may look like this:
+ </p>
+ <pre class="prettyprint linenums lang-properties">
+hibernate.dialect=org.hibernate.dialect.H2Dialect
+hibernate.connection.url=jdbc:h2:file:./target/db
+hibernate.connection.driver_class=org.h2.Driver
+hibernate.connection.username=sa
+hibernate.connection.password=</pre>
+ <p>
+ But be aware, that using this configuration-approach the database-url,
+ that is build in the application is the same that is used while testing,
+ where the database is droped and recreated by the plugin.
Because of that,
<strong>
you should never fire up this configuration on your production
<executions>
<execution>
<goals>
- <goal>export</goal>
+ <goal>drop</goal>
+ <goal>create</goal>
</goals>
</execution>
</executions>
<p>
Alternatively, it is possible, to configure the plugin via maven-properties.
Each relevant configuration-option has a corresponding maven-property
- (for a full list see the <a href="./export-mojo.html">Documentation of the export-Mojo</a>).
+ (for a full list see the <a href="./create-mojo.html">Documentation of the goal create</a>).
These are named after the
<a href="http://docs.jboss.org/hibernate/orm/4.1/manual/en-US/html_single/#configuration-hibernatejdbc">Hibernate JDBC Properties</a>:
</p>
<executions>
<execution>
<goals>
- <goal>export</goal>
+ <goal>drop</goal>
+ <goal>create</goal>
</goals>
</execution>
</executions>
</plugin>
<plugins></pre>
+ <p>
+ This way, you can reuse the same properties to provide a
+ default-configurationthe, that is build into your application, and
+ overwrite the database-url, that is used during testing to prevent
+ accidential drops of your production database.
+ </p>
<h2>Configuration through the plugin-configuration</h2>
<p>
A third way for configuring the plugin is the plugin-configuration.
<executions>
<execution>
<goals>
- <goal>export</goal>
+ <goal>drop</goal>
+ <goal>create</goal>
</goals>
</execution>
</executions>
</p>

- <a href="./export-mojo.html">Documentation of the export-Mojo</a>.
+ <a href="./create-mojo.html">Documentation of the goal create</a>.
</p>
<h2 id="precedence">Configuration-Method-Precedence</h2>
<p>
</ol>
<p>
If you are in doubt about where a configuration-value comes from, run
- maven with the <a href="./debugging.html">debug-output</a> enabled: <code>mvn -X hibernate:export</code>
+ maven with the <a href="./debugging.html">debug-output</a> enabled: <code>mvn -X hibernate:create</code>
and be aware, that maven-properties can be overwitten on the command-line,
in your <code>~/.m2/settings.xml</code> and in a profile.
</p>
<executions>
<execution>
<goals>
- <goal>export</goal>
+ <goal>drop</goal>
+ <goal>create</goal>
</goals>
</execution>
</executions>
<body>
<p>
If you are new to <code>hibernate-maven-plugin</code>, in many cases, the
- {Configuration-Method-Precedence} may be the source of configuration
- errors.
+ <a href="./configuration.html#precedence">Configuration-Method-Precedence</a>
+ may be the source of configuration errors.
To solve this problem, you should run maven with the debugging output
enabled.
For example, by executing:
</p>
<pre class="prettyprint linenums lang-html">
-mvn -X compile hibernate:export</pre>
+mvn -X compile hibernate:create</pre>
<p>
(The <code>compile</code> might be necessary, because <code>hibernate-maven-plugin</code>
has to scan the compiled classes for annotations!)
</p>
<p>
The plugin signals, that the execution was skipped by setting the maven
- property <code>$\{hibernate.export.skipped\}</code> to <code>true</code>.
+ property <code>${hibernate.schema.skipped}</code> to <code>true</code>.
This may be helpful, because other plugins like
<a href="http://mojo.codehaus.org/dbunit-maven-plugin/">dbunit-plugin</a>
<a href="./pitfalls.html#fails">may fail</a>, when the execution is skipped.
</p>
<p>
- If you need the hibernate-maven-plugin to <never skip execution automatically>,
+ If you need the hibernate-maven-plugin to <em>never skip execution automatically</em>,
you can force it to do so, if you set the parameter <code>force</code> to

- Or you may specify <code>-Dhibernate.export.force=true</code> at the command line,
