		Project p = new Project();
		p.setUserProperty("ant.file", buildFile.getAbsolutePath());
		p.init();
		ProjectHelper helper = ProjectHelper.getProjectHelper();
		p.addReference("ant.projectHelper", helper);
		helper.parse(p, buildFile);
		DefaultLogger consoleLogger = new DefaultLogger();
		consoleLogger.setErrorPrintStream(System.err);
		consoleLogger.setOutputPrintStream(System.out);
		consoleLogger.setMessageOutputLevel(Project.MSG_INFO);
		p.addBuildListener(consoleLogger);
		p.executeTarget(p.getDefaultTarget());
