| Several tasks take arguments that will be passed to another process on the command line. To make it easier to specify arguments that contain space characters, nested arg elements can be used.
value – a single command-line argument; can contain space characters. It is highly recommended to avoid the line version when possible. Ant will try to split the command line in a way similar to what a (Unix) shell would do, but may create something that is very different from what you expect under some circumstances. |

| Examples | ||||||||||||||||||||||||||||||||||||||||||||
| <arg value=”-l -a”/> is a single command-line argument containing a space character. <arg line=”-l -a”/> represents two separate command-line arguments. <arg path=”/dir;/dir2:\dir3″/> is a single command-line argument with the value \dir;\dir2;\dir3 on DOS-based systems and /dir:/dir2:/dir3 on Unix-like systems. |

In mature build systems, command-line arguments can become a hidden contract between developers, CI pipelines, and deployment processes. The real challenge appears when old parameters continue to exist for years, even after the original reason for adding them is forgotten. Periodically reviewing unused arguments, tracking their impact on build behavior, and adding automated checks for invalid inputs can help reduce technical debt. This becomes especially valuable in legacy Ant projects where small configuration changes can unexpectedly affect release workflows.
