Ant Tasks

## Ant tasks

Cayenne ships with Ant tasks that provide Ant frontend to a number of useful operations in Cayenne. These tasks are part of the cayenne-tools JAR. The following tasks are included:

- cgen - Java class generator
- cdbgen - Database schema generator
- cdataport - Data porting tool.
- cdbimport - Database schema importer.

### Importing Cayenne Tasks in build.xml

All Cayenne tasks above can be imported at once with "typedef". First a user needs to define Classpath structure to include cayenne-tools and a few depdendencies. Here they are shown relative to the Cayenne distro folder. In a real project they may be copied to the appropriate project folders and referenced accordingly:

    <path id="classpath">
       <fileset dir="lib" >
          <include name="cayenne-tools-X.X.jar" />
          <include name="cayenne-server-X.X.jar" />
          <include name="third-party/vpp-2.2.1.jar" />
       </fileset>
    </path>

And then import all tasks with "typedef", referencing Antlib descriptor in Cayenne:

    <typedef resource="org/apache/cayenne/tools/antlib.xml">
       <classpath refid="classpath"/>
    </typedef>
