The method below calls an Ant script without parameters. All you need to pass through the name and path of the Ant script:


private boolean runAntScript(String scriptName) {

File buildFile = new File(scriptName);
Project project = new Project();
DefaultLogger myLogger = new DefaultLogger();

project.setUserProperty("ant.file", buildFile.getAbsolutePath());
myLogger.setErrorPrintStream(System.err);
myLogger.setOutputPrintStream(System.out);
myLogger.setMessageOutputLevel(Project.MSG_INFO);

project.addBuildListener(myLogger);

try {
project.fireBuildStarted();
project.init();
ProjectHelper helper = ProjectHelper.getProjectHelper();
project.addReference("ant.projectHelper", helper);
helper.parse(project, buildFile);
project.executeTarget(project.getDefaultTarget());
project.fireBuildFinished(null);
} catch (Exception e) {
project.fireBuildFinished(e);
return false;
}

return true;
}

You will need the ant libraries in the application classpath. Notice that the above example sends the script output to default System.out and runs the default script start target.
