Class AntFetch

public class AntFetch extends Task

Identical (copy and paste, even) to the 'Ant' task, with the exception that properties from the new project can be copied back into the original project. Build a sub-project.

  <target name="foo" depends="init">
    <ant antfile="build.xml" target="bar" >
      <property name="property1" value="aaaaa" />
      <property name="foo" value="baz" />
    </ant> </target> <target name="bar"
 depends="init"> <echo message="prop is ${property1}
 ${foo}" /> </target>

Developed for use with Antelope, migrated to ant-contrib Oct 2003.

Credit to Costin for the original <ant> task, on which this is based.

Method Detail

addReference

public void addReference(AntFetch.Reference r)

Reference element identifying a data type to carry over to the new project.

Parameters: r The feature to be added to the Reference attribute

createProperty

public Property createProperty()

Property to pass to the new project. The property is passed as a 'user property'

Returns: Description of the Return Value

execute

public void execute()

Do the execution.

Throws: BuildException Description of the Exception

handleErrorOutput

protected void handleErrorOutput(String line)

Pass output sent to System.err to the new project.

Parameters: line Description of the Parameter

Since: Ant 1.5

handleOutput

protected void handleOutput(String line)

Pass output sent to System.out to the new project.

Parameters: line Description of the Parameter

Since: Ant 1.5

init

public void init()

Creates a Project instance for the project to call.

setAntfile

public void setAntfile(String s)

The build file to use. Defaults to "build.xml". This file is expected to be a filename relative to the dir attribute given.

Parameters: s The new antfile value

The directory to use as a base directory for the new Ant project. Defaults to the current project's basedir, unless inheritall has been set to false, in which case it doesn't have a default value. This will override the basedir setting of the called project.

Parameters: d The new dir value

setInheritAll

public void setInheritAll(boolean value)

If true, pass all properties to the new Ant project. Defaults to true.

Parameters: value The new inheritAll value

setInheritRefs

public void setInheritRefs(boolean value)

If true, pass all references to the new Ant project. Defaults to false.

Parameters: value The new inheritRefs value

setOutput

public void setOutput(String s)

Filename to write the output to. This is relative to the value of the dir attribute if it has been set or to the base directory of the current project otherwise.

Parameters: s The new output value

setReturn

public void setReturn(String r)

Set the property or properties that are set in the new project to be transfered back to the original project. As with all properties, if the property already exists in the original project, it will not be overridden by a different value from the new project.

Parameters: r the name of a property in the new project to set in the original project. This may be a comma separate list of properties.

setTarget

public void setTarget(String s)

The target of the new Ant project to execute. Defaults to the new project's default target.

Parameters: s The new target value
