java - 无法从代码执行 ANT

Question

我正在使用 Eclipse Helios，并且我有 ANT 文件来执行一些任务(编译 java 代码)。 但我无法使用代码执行 ANT 文件。这些是我的代码:

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

当我运行它时，我收到此错误:

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

谢谢

这意味着 AntRunner 不在您的类路径上。您正在使用的类是 Eclipse 的一部分。您需要从 Eclipse 中找到包含该类的 JAR，并将其添加到您的类路径中。

或者，我建议您使用不同的方法来启动 Ant 构建。快速谷歌搜索出现了this ，例如。
