Apache Ant 区别 - exec 与 apply [英] Apache Ant difference - exec vs apply

问题描述

谁能告诉我 和 在 Apache Ant 中的区别?

Can anyone tell me the difference between <exec> and <apply> in Apache Ant?

推荐答案

主要区别在于apply 适用于资源集合 - 文件集、目录集等 - 例如，您可以为文件集的每个成员运行一次脚本.exec 不对文件集进行操作；任务的每个实例只运行一个外部程序.否则，任务非常相似.

The main difference is that apply works for a resource collection - fileset, dirset and the like - so you can, for example, run a script once for each member of a fileset. exec doesn't operate on a fileset; each instance of the task only runs a single external program. Otherwise the tasks are quite similar.
