/*
* AntRunner.java
*/

import java.io.File;
import org.apache.tools.ant.DefaultLogger;
import org.apache.tools.ant.Project;
import org.apache.tools.ant.ProjectHelper;
import org.apache.tools.ant.taskdefs.Ant;


public class AntRunner {

public AntRunner() {
}

public static void main(String args[]) throws Exception {
 File buildFile = new File("/path/to/build.xml");
 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());
}
