public final class JarLibManifestTask
extends Task

Generates a manifest that declares all the dependencies. The dependencies are determined by looking in the specified path and searching for Extension / "Optional Package" specifications in the manifests of the jars.

Prior to JDK1.3, an "Optional Package" was known as an Extension. The specification for this mechanism is available in the JDK1.3 documentation in the directory $JDK_HOME/docs/guide/extensions/versioning.html. Alternatively it is available online at http://java.sun.com/j2se/1.3/docs/guide/extensions/versioning.html.

destfile - The location where generated manifest is placed.

addConfiguredExtension

public void addConfiguredExtension(ExtensionAdapter extensionAdapter)
                            throws BuildException
Adds an extension that this library implements.

Parameters:
extensionAdapter - an extension that this library implements.
BuildException

addConfiguredDepends

public void addConfiguredDepends(ExtensionSet extensionSet)
Adds a set of extensions that this library requires.

Parameters:
extensionSet - a set of extensions that this library requires.

addConfiguredOptions

public void addConfiguredOptions(ExtensionSet extensionSet)
Adds a set of extensions that this library optionally requires.

Parameters:
extensionSet - a set of extensions that this library optionally requires.

addConfiguredAttribute

public void addConfiguredAttribute(ExtraAttribute attribute)
Adds an attribute that is to be put in main section of manifest.

Parameters:
attribute - an attribute that is to be put in main section of manifest.

execute

public void execute()
             throws BuildException
Description copied from class: Task
Called 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.

Overrides:
execute in class Task
Throws:
BuildException - if something goes wrong with the build
