通过Tomcat服务器中部署的java类运行build.xml时出错

我在以下代码的帮助下通过Java类运行ant构建文件：

p.setUserProperty("ant.file", buildFile.getAbsolutePath());
p.init();
ProjectHelper helper = ProjectHelper.getProjectHelper();
p.addReference("ant.projectHelper", helper);
helper.parse(p, buildFile);
p.executeTarget(p.getDefaultTarget());

当我部署WAR文件并调用同一类时，会出现以下错误：

WAR文件中存在Ant jar。如果在主程序中运行，同样的代码也可以工作。
