Getting Hibernate3's hbm2ddl to generate SQL but not wipe my db?

[Lally Singh <la...@gmail.com>]

Hey everyone, I'm trying to get the plugin to generate my SQL code,
but I can't seem to do it without it trying to connect to my db.

Is there an option that tells it to generate the .sql, but not run it,
clobbering my existing db?

Thanks,

-ls

Hi,

I'm using this and it does not need a running database :

    <build>
        <plugins>
            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>hibernate3-maven-plugin</artifactId>
                <configuration>
                    <components>
                        <component>
                            <name>hbm2ddl</name>
                        </component>
                    </components>
                    <componentProperties>
                        <implementation>jpaconfiguration</implementation>
                        <outputfilename>entities-schema.sql</outputfilename>
                        <drop>true</drop>
                        <create>true</create>
                        <update>false</update>
                        <export>false</export>
                        <ejb3>true</ejb3>
                    </componentProperties>
                </configuration>
                <executions>
                    <execution>
                        <phase>process-classes</phase>
                        <goals>
                            <goal>hbm2ddl</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
        <extensions>
            <extension>
                <groupId>org.apache.derby</groupId>
                <artifactId>derbyclient</artifactId>
                <version>10.3.1.4</version>
            </extension>
        </extensions>
    </build>

The extension derbyclient is here because I use DerbyDialect.
