Parameters:
output - a line of output
Since:
Ant 1.6.2

handleInput

public int handleInput(byte[] buffer,
                       int offset,
                       int length)
                throws java.io.IOException
Process input into the ant task

Overrides:

Parameters:
buffer - the buffer into which data is to be read.
offset - the offset into the buffer at which data is stored.
length - the amount of data to read
Returns:
the number of bytes read
Throws:
java.io.IOException - if the data cannot be read
Since:
Ant 1.6.2

Task.handleInput(byte[], int, int)

handleFlush

public void handleFlush(java.lang.String output)
Pass output sent to System.out to the new project.

Overrides:
handleFlush in class Task
Parameters:
output - The output to log. Should not be null.
Since:
Ant 1.6.2

handleErrorOutput

public void handleErrorOutput(java.lang.String output)
Pass output sent to System.err to the new project.

Overrides:
handleErrorOutput in class Task
Parameters:
output - The error output to log. Should not be null.
Since:

Overrides:
handleErrorFlush in class Task
Parameters:
output - The error output to log. Should not be null.
Since:

execute

public void execute()
Runs the various sub-builds.

Overrides:
execute in class Task

setAntfile

public void setAntfile(java.lang.String antfile)
This method builds the file name to use in conjunction with directories.

Defaults to "build.xml". If genericantfile is set, this attribute is ignored.

Parameters:
antfile - the short build file name. Defaults to "build.xml".

setGenericAntfile

public void setGenericAntfile(java.io.File afile)
This method builds a file path to use in conjunction with directories.

Use genericantfile, in order to run the same build file with different basedirs.

If this attribute is set, antfile is ignored.

Parameters:
afile - (path of the generic ant file, absolute or relative to project base directory)

setFailonerror

public void setFailonerror(boolean failOnError)
Sets whether to fail with a build exception on error, or go on.

Parameters:
failOnError - the new value for this boolean flag.

setTarget

public void setTarget(java.lang.String target)
The target to call on the different sub-builds. Set to "" to execute the default target.

Parameters:
target - the target


setVerbose

public void setVerbose(boolean on)
Enable/ disable verbose log messages showing when each sub-build path is entered/ exited. The default value is "false".

Parameters:
on - true to enable verbose mode, false otherwise (default).

setOutput

public void setOutput(java.lang.String s)
Corresponds to <ant>'s output attribute.

Parameters:
s - the filename to write the output to.

setInheritall

public void setInheritall(boolean b)
Corresponds to <ant>'s inheritall attribute.

Parameters:
b - the new value for this boolean flag.

setInheritrefs

public void setInheritrefs(boolean b)
Corresponds to <ant>'s inheritrefs attribute.

Parameters:
b - the new value for this boolean flag.

addProperty

public void addProperty(Property p)
Corresponds to <ant>'s nested <property> element.

Parameters:
p - the property to pass on explicitly to the sub-build.

addReference

public void addReference(Ant.Reference r)
Corresponds to <ant>'s nested <reference> element.

Parameters:
r - the reference to pass on explicitly to the sub-build.

addPropertyset

public void addPropertyset(PropertySet ps)
Corresponds to <ant>'s nested <propertyset> element.

Parameters:
ps - the propertset

addDirset

public void addDirset(DirSet set)
Adds a directory set to the implicit build path.

Note that the directories will be added to the build path in no particular order, so if order is significant, one should use a file list instead!

Parameters:
set - the directory set to add.

addFileset

public void addFileset(FileSet set)
Adds a file set to the implicit build path.

Note that the directories will be added to the build path in no particular order, so if order is significant, one should use a file list instead!

Parameters:
set - the file set to add.

addFilelist

public void addFilelist(FileList list)
Adds an ordered file list to the implicit build path.

Note that contrary to file and directory sets, file lists can reference non-existent files or directories!

Parameters:
list - the file list to add.

setBuildpath

public void setBuildpath(Path s)
Set the buildpath to be used to find sub-projects.

Parameters:
s - an Ant Path object containing the buildpath.

createBuildpath

public Path createBuildpath()
Creates a nested build path, and add it to the implicit build path.

Returns:
the newly created nested build path.

createBuildpathElement

public Path.PathElement createBuildpathElement()
Creates a nested <buildpathelement>, and add it to the implicit build path.

Returns:
the newly created nested build path element.

setBuildpathRef

public void setBuildpathRef(Reference r)
Buildpath to use, by reference.

Parameters:
r - a reference to an Ant Path object containing the buildpath.
