不能从代码

Question

执行ANT我正在使用Eclipse Helios，并且我有ANT文件来完成一些任务（编译java代码）。 但我无法使用代码执行ANT文件。这是我的代码：

AntRunner runner = new AntRunner(); 
runner.setBuildFileLocation(fileDir); 
runner.setArguments("-Dmessage=Building -verbose"); 

当我运行它，我得到这个错误：

谁能告诉我这是什么意思？我可以使用Eclipse的右键单击功能执行ANT，但我无法通过我的代码调用它。

感谢

这意味着AntRunner是不是在你的类路径中。您正在使用的类是Eclipse的一部分。您需要从Eclipse中找到哪个JAR包含该类并将其添加到类路径中。

另外，我建议你使用不同的方法来启动你的Ant构建。例如，快速的Google搜索出现在this。
