Class ImportTask
- All Implemented Interfaces:
Cloneable
It must be 'top level'. On execution it will read another Ant file into the same Project.
Important: Trying to understand how relative file references resolved in deep/complex build hierarchies - such as what happens when an imported file imports another file can be difficult. Use absolute references for enhanced build file stability, especially in the imported files.
Examples:
<import file="../common-targets.xml"/>
Import targets from a file in a parent directory.
<import file="${deploy-platform}.xml"/>
Import the project defined by the property deploy-platform.

Method Details
-
setOptional
public void setOptional(boolean optional) sets the optional attribute- Parameters:
optional- if true ignore files that are not present, default is false
-
setFile
the name of the file to import. How relative paths are resolved is still in flux: use absolute paths for safety.- Parameters:
file- the name of the file
-
setAs
The prefix to use when prefixing the imported target names.- Parameters:
prefix- String- Since:
- Ant 1.8.0
-
setPrefixSeparator
The separator to use between prefix and target name, default is ".".- Parameters:
s- String- Since:
- Ant 1.8.0
-
add
The resource to import.- Parameters:
r- ResourceCollection- Since:
- Ant 1.8.0
-
execute
public void execute()Description copied from class:TaskCalled by the project to let the task do its work. This method may be called more than once, if the task is invoked more than once. For example, if target1 and target2 both depend on target3, then running "ant target1 target2" will run all tasks in target3 twice. -
isInIncludeMode
protected final boolean isInIncludeMode()Whether the task is in include (as opposed to import) mode.In include mode included targets are only known by their prefixed names and their depends lists get rewritten so that all dependencies get the prefix as well.
In import mode imported targets are known by an adorned as well as a prefixed name and the unadorned target may be overwritten in the importing build file. The depends list of the imported targets is not modified at all.
- Returns:
- boolean

- Ant 1.8.0
