Adding Data Model Generation to a project

API Project

Impl Project

1. Add directory src/main/dmgen with only generator.xml (datamodel.xml will be copied from API project using the plugin calls shown below).  Contents of generator.xml e.g.

   <GeneratorConfig> <Generate concept="tableDefinitions" package="at.iteg.tis.prediction.impl.schema"/> <Generate concept="daoInterface" package="at.iteg.tis.prediction.impl.dao" dtoPackage="at.iteg.tis.prediction.api.dto" joinDtoPackage="at.iteg.tis.prediction.api.joinDto"/> <Generate concept="jdbcDAO" package="at.iteg.tis.prediction.impl.dao.jdbc" dtoPackage="at.iteg.tis.prediction.api.dto" joinDtoPackage="at.iteg.tis.prediction.api.joinDto" supportImpExp="false" tableDefinitionsClass="at.iteg.tis.prediction.impl.schema.TableDefinitions" daoInterfacePackage="at.iteg.tis.prediction.impl.dao"/> </GeneratorConfig>

2. In pom.xml: Add call to maven-clean-plugin

   <plugin> <artifactId>maven-clean-plugin</artifactId> <configuration> <filesets> <fileset> <directory>src/generated/java</directory> <includes> <include>at</include> <include>**/*.java</include> </includes> <followSymlinks>false</followSymlinks> </fileset> </filesets> </configuration> </plugin>

    

    

3. In pom.xml: Add call to maven-dependency-plugin

   <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency-plugin</artifactId> <executions> <execution> <id>unpack</id> <phase>generate-sources</phase> <goals> <goal>unpack</goal> </goals> <configuration> <artifactItems> <artifactItem> <groupId>at.iteg.prediction</groupId> <artifactId>prediction.api</artifactId> <outputDirectory>src/main</outputDirectory> <includes>dmgen/datamodel.xml</includes> </artifactItem> </artifactItems> </configuration> </execution> </executions> </plugin>

    

    

4. In pom.xml: Finally add call to dmgen-maven-plugin

   <plugin> <groupId>org.clazzes.dmgen</groupId> <artifactId>dmgen-maven-plugin</artifactId> <executions> <execution> <phase>generate-sources</phase> <goals> <goal>dmgen</goal> </goals> </execution> </executions> <configuration> <dmSpecFile>${basedir}/src/main/dmgen/datamodel.xml</dmSpecFile> <dmConfigFile>${basedir}/src/main/dmgen/generator.xml</dmConfigFile> <outputDir>${basedir}/src/generated</outputDir> </configuration> </plugin>

    

    

5. Work around a battle between Eclipse and Maven:

   <pluginManagement> <plugins> <!-- The following boilerplate code is just for convincing eclipse that unpack is not an unsupported goal. --> <!--This plugin's configuration is used to store Eclipse m2e settings only. It has no influence on the Maven build itself. --> <plugin> <groupId>org.eclipse.m2e</groupId> <artifactId>lifecycle-mapping</artifactId> <version>1.0.0</version> <configuration> <lifecycleMappingMetadata> <pluginExecutions> <pluginExecution> <pluginExecutionFilter> <groupId> org.apache.maven.plugins </groupId> <artifactId> maven-dependency-plugin </artifactId> <versionRange> [2.1,) </versionRange> <goals> <goal>unpack</goal> </goals> </pluginExecutionFilter> <action> <execute> <runOnIncremental>false</runOnIncremental> <runOnConfiguration>true</runOnConfiguration> </execute> </action> </pluginExecution> </pluginExecutions> </lifecycleMappingMetadata> </configuration> </plugin> </plugins> </pluginManagement>

    

    

6. Necessary dependencies (sql-util, jdbc2xml):

   <dependency> <groupId>org.clazzes.util</groupId> <artifactId>sql-util</artifactId> </dependency> <dependency> <groupId>org.clazzes</groupId> <artifactId>jdbc2xml</artifactId> </dependency>

Subversion

1. Refresh in Eclipse

2. Delete all possibly (as result of testing the changes above) generated sources below src/generated/java.  I.e. src/generated/java stays, but not src/generated/java/at.

3. Commit the changes so far.

4. Perform a maven build both on api and on impl project

5. Refresh both projects in eclipse

6. Both in api and in impl project, Team -> Add to svn.ignore by name the top level package below src/generated/java, e.g. "at".

7. Commit.

Java Build Path

1. In both projects (api and impl), add src/generated/java to the Build Path.

2. Commit.
