Accessing maven compile classpath in plugin

[Rahul Khot]

I am writing a plugin for generating JAXB 1.6 sources . The plugin is
written in ant.  How do I access the compile classpath in the plugin.

 

My plugin code:

<project>

  <!--<property name="repo.home" value="C:/Documents and
Settings/user/.m2/repository"/>-->

 

 

<taskdef name="xjc" classname="com.sun.tools.xjc.XJCTask">

            <!- NEED TO SET CLASSPATH HERE SO THAT XJC task can be accessed
-->

 

                        

</taskdef>

 

 

  <target name="hello">

            <mkdir
dir="${targetDirectory}/generated-sources/java/jaxb1.6Plugin"/>

            <echo>XSD File Name ${xsdFileName}</echo>

            <echo>Dir to write generated source to
"${targetDirectory}/generated-sources/java/jaxb1.6Plugin</echo>

            <echo>Package name ${packageName}</echo>

            <xjc schema="${xsdFileName}" removeOldOutput="yes"
target="${targetDirectory}/generated-sources/java/jaxb1.6Plugin"
package="${packageName}"/>

  </target>

</project>
