Apache Ant Concat Task

Concatenation is used to concat one or more files to a single file. A new file will be created if it does not exist unless the resource list is empty and ignoreempty is true.

Since Apache Ant 1.7.1, this task can be used as a resource collection that will return exactly one resource.

Resource collections are used to select which resources are to be concatenated. There is no singular attribute to specify a single resource to concatenation file.
