How to configure maven hbm2hbmxml and hbm2java to run one after the other in mvn clean install

Question

Hi, I need to be able to call mvn clean install and have maven call hibernate3:hbm2hbmxml to generate the mapping files from a database and after than call hbm2java to get the Java files and then have maven compile those newly created Java files. Has anyone done this before?

Thanks

Answer 1

Maven lifecycle

mvn clean dependency:copy-dependencies package

If this were to be executed, the clean phase will be executed first (meaning it will run all preceeding phases of the clean lifecycle, plus the clean phase itself), and then the dependency:copy-dependencies goal, before finally executing the package phase (and all its preceeding build phases of the default lifecycle).

So, perhaps:

mvn clean hibernate3:hbm2hbmxml hibernate3:hbm2java package

That said, I'd recommend against perpetually generating classes. This makes you very inflexible.

After your comment, it seems like an "unwise" behaviour from the hibernate plugin. You can bypass that by "manually" copying the required files to the desired directory, using the Maven antrun plugin.

the following config works for me. (sample is with Derby database and 1 table)
mvn clean package does it all.

the plugin configuration:

<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>hibernate3-maven-plugin</artifactId>
<version>2.2</version>
<executions>
    <execution>
        <id>hbm2hbmxml</id>
        <phase>generate-sources</phase>
        <goals>
            <goal>hbm2hbmxml</goal>
        </goals>
        <configuration>
            <components>
                <component>
                    <name>hbm2hbmxml</name>
                    <outputDirectory>src/main/resources</outputDirectory>
                </component>
            </components>
        </configuration>
    </execution>
    <execution>
        <id>hbm2java</id>
        <phase>generate-sources</phase>
        <goals>
            <goal>hbm2java</goal>
        </goals>
        <configuration>
            <components>
                <component>
                    <name>hbm2java</name>
                    <implementation>configuration</implementation>
                </component>
            </components>
            <componentProperties>
                <jdk5>true</jdk5>
                <configurationfile>/src/main/resources/hibernate.cfg.xml
                </configurationfile>
            </componentProperties>
        </configuration>
    </execution>
</executions>
<dependencies>
    <dependency>
        <groupId>org.apache.derby</groupId>
        <artifactId>derbyclient</artifactId>
        <version>10.4.2.0</version>
    </dependency>
</dependencies>

hibernate.cfg.xml:

<hibernate-configuration>
<session-factory>
    <property name="connection.url">jdbc:derby://localhost:1527/demo</property>
    <property name="connection.username">app</property>
    <property name="connection.driver_class">org.apache.derby.jdbc.ClientDriver</property>
    <property name="dialect">org.hibernate.dialect.DerbyDialect</property>
    <property name="connection.password">password</property>
    <property name="hibernate.show_sql">true</property>

    <mapping resource="Tag.hbm.xml" />
</session-factory>

Hola,

If you want to have your model java files (obtained by reveng) compiled, you don't need to run hbm2hbmxml.

plugin configuration:

    <build>
    <plugins>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>hibernate3-maven-plugin</artifactId>
            <version>2.2</version>
            <configuration>
                <components>
                    <component>
                        <name>hbm2java</name>
                        <outputDirectory>src/main/java</outputDirectory>
                        <implementation>jdbcconfiguration</implementation>
                    </component>
                </components>
                <componentProperties>
                    <revengfile>/src/main/resources/reveng/model.reveng.xml</revengfile>
                    <propertyfile>/src/main/resources/META-INF/hibernate.properties</propertyfile>
                    <jdk5>true</jdk5>
                    <ejb3>true</ejb3>
                </componentProperties>
            </configuration>
            <dependencies>
                <dependency>
                    <groupId>mysql</groupId>
                    <artifactId>mysql-connector-java</artifactId>
                    <version>5.0.8</version>
                </dependency>
                <dependency>
                    <groupId>cglib</groupId>
                    <artifactId>cglib-nodep</artifactId>
                    <version>2.1_3</version>
                </dependency>
            </dependencies>             
        </plugin>
    </plugins>
</build>

hibernate.properties :

hibernate.dialect = org.hibernate.dialect.MySQLInnoDBDialect
hibernate.connection.driver_class = com.mysql.jdbc.Driver
hibernate.connection.url = jdbc:mysql://localhost:3306/YOUR_DB
hibernate.connection.username = yourUsrName
hibernate.connection.password= yourPwd
hibernate.default_schema = YOUR_DB

model.reveng.xml :

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-reverse-engineering SYSTEM "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd"&gt;
<hibernate-reverse-engineering>

    <table-filter match-name=".*" package="your.package.here/>


</hibernate-reverse-engineering>

you fire this with:

mvn clean hibernate3:hbm2java compile

if you want it to be fired just with:

mvn clean compile

add the "executions" tag in your plugin definition

                <executions>
                <execution>
                    <phase>compile</phase>
                    <goals><goal>hbm2java</goal></goals>
                </execution>
            </executions>
