Ant: The Definitive Guide

Name

dependset

Synopsis

Manages dependencies between files, removing all target files if any are out-of-date with respect to a group of source files. This task does not perform a positional, file-by-file timestamp comparison. Instead, it compares the most recent timestamp from the group of source files to the most recent timestamp from the group of all target files.

Attributes

None.

Content

Requires at least one of either <srcfileset> or <srcfilelist>, as well as at least one <targetfileset> or <targetfilelist>. The fileset elements are used when missing files are not important. When using filelists, on the other hand, any missing files cause all target files to be removed.

0..n nested <srcfileset> elements (1.4)

All files in this fileset are compared against all files specified by the <targetfileset> and <targetfilelist> elements.

0..n nested <srcfilelist> elements (1.4)

All files in this filelist are compared against all files specified by the <targetfileset> and <targetfilelist> elements.

0..n nested <targetfileset> elements (1.4)

All files in this fileset are compared against all files specified by the <srcfileset> and <srcfilelist> elements. If any are older, all are deleted.

0..n nested <targetfilelist> elements (1.4)

All files in this filelist are compared against all files specified by the <srcfileset> and <srcfilelist> elements. If any are older, all are deleted.
