## \ImportTask
jump to top

Imports another build file into the current project.

Targets and properties of the imported file can be overrridden by targets and properties of the same name declared in the importing file.

The imported file will have a new synthetic property of "phing.file." declared which gives the full path to the imported file. Additionally each target in the imported file will be declared twice: once with the normal name and once with "." prepended. The "." synthetic targets allow the importing file a mechanism to call the imported files targets as dependencies or via the or task mechanisms.
