Writing an Ant Task

You must have something like this into your Ant build.xml file:

<project name="OwnTaskExample" default="main" basedir=".">
<!-- task definition -->
<taskdef name="plantuml" classname="net.sourceforge.plantuml.ant.PlantUmlTask" classpath="plantuml.jar" />

<!-- process ./src files -->
<target name="main">
<plantuml dir="./src" />
</target>
</project>

The Ant task processes all .c, .h, .cpp, .tex, .html, .htm or .java of the provided directory (./src in this example). It looks for @startXYZ and generates .png images.

Output Directory

You can also specify a output directory for all generated images, using output tag.

<!-- Put images in c:/images directory -->
<target name="main">
<plantuml dir="./src" output="c:/images" />
</target>

Recurse through directories

You can also use Ant standard fileset or filelist.

For example, if you want to process all java file in c:/src and subdirectories, (except files ending by Test.java), and generate images into d:/images, you can use:

<target name="main">
<plantuml output="d:/images" >
<fileset dir="c:/src">
<include name="**/*.java" />
<exclude name="**/*Test.java" />
</fileset>
</plantuml>
</target>

SVG or EPS Support

You can also use format="svg" or format="eps" in the Ant task definition.

<target name="main">
<plantuml dir="./src" format="svg" />
</target>

Configuration file

You can also provide a configuration file which will be included before each diagram.

<target name="main">
<plantuml dir="./src" config="./config.cfg" />
</target>
