</project>

要注意的是，本次我将ant 默认的 build.xml 文件名改成了  BuildDesEncryptor.xml

该操作会导致一个问题：

在执行  rerun 这个  target 的时候，竟然报出错误说找不到 build.xml 文件

很显然是因为我没有使用默认的文件名称所致。

<ant antfile="BuildDesEncryptor.xml" target="execute.class" />

上面这行我之前是按如下的方式写的

<ant target="execute.class" />

可见：

如果构建文件没有使用默认的 build.xml 作为文件名的话

ant 标签里最好还是给写上 antfile 这个属性。
