Want to load workflow and lifecycles using build.xml through ANT command
Prepared build.xml as below
<target name="deploy" depends="init">
<echo message="Deploying workflow ${workflow.file}..."/>
<java jar="" fork="true" failonerror="true">
<arg value="wt.load.LoadFromFile"/>
<arg value="${workflow.dir}/${workflow.file}"/>
<classpath>
<pathelement path="${wt.bin}"/>
</classpath>
</java>
</target>
Suggest the correct way to deploy data in windchill 12.0
