Answer 1

在此处检查Execute Ant From Your Application并查看此示例：

      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

这是比调用Runtime.exec更好的解决方案

与其尝试单独启动 windows 可执行文件，不如使用 Ant API 是一种更强大、更灵活的解决方案。 ant 本身包含文档，它们不在线...

试试Runtime.getRuntime().exec("cmd /c start ant.bat"); 取自如何从我的 Java 应用程序运行批处理文件？
