- Class Summary
  Class | Description
  --- | ---
  AntClassLoader | Used to load classes within ant with a different classpath from that used to start ant.
  AntTypeDefinition | This class contains all the information on a particular ant type, the classname, adapter and the class it should be assignable from.
  ArgumentProcessorRegistry | The global registry for `ArgumentProcessor`s.
  BuildEvent | Class representing an event occurring during a build.
  ComponentHelper | Component creation and configuration.
  DefaultDefinitions | Default definitions.
  DefaultLogger | Writes build events to a PrintStream.
  DemuxInputStream | Passes input requests to the project object for demuxing into individual tasks and threads.
  DemuxOutputStream | Logs content written by a thread and forwards the buffers onto the project object which will forward the content to the appropriate task.
  Diagnostics | A little diagnostic helper that output some information that may help in support.
  DirectoryScanner | Class for scanning a directory for files/directories which match certain criteria.
  ExtensionPoint | An extension point build files can provide as a place where other build files can add new dependencies.
  IntrospectionHelper | Helper class that collects the methods a task or nested element holds to set attributes, create nested elements or hold PCDATA elements.
  IntrospectionHelper.Creator | creator - allows use of create/store external to IntrospectionHelper.
  Location | Stores the location of a piece of text within a file (file name, line number and column number).
  MagicNames | Magic names used within Ant.
  Main | Command line entry point into Ant.
  NoBannerLogger | Extends DefaultLogger to strip out empty targets.
  PathTokenizer | A Path tokenizer takes a path and returns the components that make up that path.
  Project | Central representation of an Ant project.
  ProjectComponent | Base class for components of a project, including tasks and data types.
  ProjectHelper | Configures a Project (complete with Targets and Tasks) based on a build file.
  ProjectHelper.OnMissingExtensionPoint | Possible value for target's onMissingExtensionPoint attribute.
  ProjectHelperRepository | Repository of `ProjectHelper` found in the classpath or via some System properties.
  PropertyHelper | Deals with properties - substitution, dynamic properties, etc.
  RuntimeConfigurable | Wrapper class that holds the attributes of an element, its children, and any text within it.
  Target | Class to implement a target object with required parameters.
  Task | Base class for all tasks.
  TaskAdapter | Uses introspection to "adapt" an arbitrary Bean which doesn't itself extend Task, but still contains an execute method and optionally a setProject method.
  TaskConfigurationChecker | Helper class for the check of the configuration of a given task.
  UnknownElement | Wrapper class that holds all the information necessary to create a task or data type that did not exist when Ant started, or one which has had its definition updated to use a different implementation class.
  XmlLogger | Generates a file in the current directory with an XML description of what happened during a build.

- Exception Summary
  Exception | Description
  --- | ---
  BuildException | Signals an error condition during a build
  ExitException | Used to report exit status of classes which call System.exit().
  ExitStatusException | BuildException + exit status.
  UnsupportedAttributeException | Used to report attempts to set an unsupported attribute
  UnsupportedElementException | Used to report attempts to set an unsupported element When the attempt to set the element is made, the code does not not know the name of the task/type based on a mapping from the classname to the task/type.
