Well folks, I worked it out, courtesy of this page:
http://www.onjava.com/pub/a/onjava/2002/07/24/antauto.html?page=1
This is the code I used to acheive the objectives oulined in the
previous message:
--------------------------------------------------------------------
Project project = new Project();
project.init();
DefaultLogger logger = new DefaultLogger();
logger.setMessageOutputLevel(Project.MSG_INFO);
logger.setErrorPrintStream(System.err);
logger.setOutputPrintStream(System.out);
project.addBuildListener(logger);
File buildFile = new File("buildhtml.xml");
ProjectHelper.configureProject(project, buildFile);
project.setProperty("ant.file", buildFile.getAbsolutePath());
project.setProperty("item", "ant");
project.setProperty("inputdir", "src/items/ant");
project.setProperty("outputdir", "build/items/ant");
project.setProperty("graphics.prefix", "../../");
try {
project.executeTarget("checkifuptodate");
} catch(Exception e) {System.err.println(e.getMessage());}
// rest of program goes here
--------------------------------------------------------------------
Pretty cool huh! ;)
