AspectJ is an aspect-oriented extension to Java. This task compiles a source tree using the AspectJ compiler -- AJC.

Actually, Anakia is more than just an Ant task, it is a an XML transformation tool based on JDOM, Velocity and Ant.

Checkstyle is a development tool to help programmers write Java code that adheres to a coding standard. Its purpose is to automate the process of checking Java code, and to spare humans of this boring (but important) task.

Checkstyle can be run via an Ant task or a command line utility.

Removes unneeded imports. Formats your import sections. Flags ambiguous imports.

Clover is an Ant-based Code Coverage tool. It can be used seamlessly with Ant-based projects. It provides method, statement, and branch coverage analysis, and has rich reporting in XML, HTML or via a Swing GUI.

Recursive build support (call ant on every package level, and only build files in that package or in that package and everything below) with seperation of source and output.

The task generates build files in any subdirectory (except for CVS-directories) for you. Only place one build.xml file in the top and call target 'setup' or 'rescan'.

A little CVS client that can be useful when people are behind corporate firewall that blocks any cvs communications. It uses the ViewCVS web interface to access the CVS repository via standard http, and downloads all the files present in it.

It works from the command line or as an Ant task.

Ant task for running the Doxygen documentation system.

Builds a JAR file based on class dependencies rather than simply the contents of a directory

Removes unnecessary import statements from a Java source code file.

Checks whether a given directory structure conforms to certain rules that are defined via nested elements of the task.

An Ant Plug-in for the Java Source Code Formatter Jalopy.

A task to compile Java sources and manage class file dependencies. Functionality is equivalent to that of standard Javac and Depend tasks combined, with improved dependency checking.

There are two different sets of tasks to help build Java 2 Platform, Micro Edition (J2ME) applications.

This set supports CLDC and the K Virtual Machine (KVM):

And this set works with the J2ME Wireless Toolkit and MIDP for PalmOS:

Ant tasks that generate record classes for VisualAge for Java from Cobol copy books.

PMD checks Java source code for unused variables, unnecessary object creation, etc

The styler task makes useful combinations of XSLT transformations easy to specify in an Ant build file. Like the built-in Ant task style, styler can apply a single transformation to a set of XML files. But it can also:

• handle multiple transformations, in parallel or pipelined.
• enable transformations that split or merge files
• process non-XML files, especially HTML (based on JTidy)
• apply non-XSLT transformation, especially "regular fragmentations"
• use any custom XMLReader or XMLFilter class to handle new file formats and transformation techniques.

Tim is a handy utility that can be executed on the command line or via Ant that automatically formats your import declarations. Tim is capable of removing unused imports, expanding or collapsing imports and even organising them into pre-determined groups.

TiniAnt is an Ant task to support building applications for the TINI.

Venus Application Publisher's (Vamp) Ant Task Suite allows you to sign and package your applications into relocatable Web Archives that you can drop into your web server for single-click launching using Java Web Start or into single Java Archive installers that serve up their content through a built-in, multi-threaded, ultra light-weight web server.

WOProject provides a set of tools to work with WebObjects 5.1 independent from platform and IDE. It significantly improves developer productivity and makes complex project structures more flexible compared to traditional Makefile-based approach.

XDoclet is an extended Javadoc Doclet engine for use in Ant. It lets you create custom Javadoc @tags and based on those tags generates source code or other files (such as xml-ish deployment descriptors). Templates and matching tasks are provided to generate EJB and web application deployment descriptors.

XmlTask provides a simple means to modify XML documents without having to learn XSLT. A simple path reference to an XML node specifies the node you want to change, and how you want to allow XML insertion and removal, or attribute changes. The emphasis is on providing the simplest means to perform common XML replacements

Validates XML files against the RELAX NG alternative to XML Schema. The Jing task for Ant allows you to efficiently validate multiple files against multiple RELAX NG patterns and integrate RELAX NG validation with other XML processing.

miniRMI is a freeware opensource library that serves as a lightweight replacement for the original java.rmi packages and is suitable especially for applets. Ant 1.4+ <rmic> adapter included.

A plugin that integrates Ant into the jEdit editor.

An AddIn that integrates Ant with the JDeveloper IDE

An OpenTool that integrates Ant into the JBuilder IDE.

A plugin that integrates Ant into the Jext editor.

Eclipse is a universal tool platform with Ant integration.

Java IDE with refactoring support and Ant integration.

The Java Development Environment for Emacs (JDEE) supports Apache Ant as one of three built-in ways to build your applications.

A module that integrates Ant into the NetBeans or Forte for Java IDEs.

RadPak comes with the (free) HP Bluestone HPAS J2EE server, and is primarily a GUI tool for packaging and deploying java web and EJB applications as WAR and EAR files. The tool is ant based, and can be used with as a GUI for general ant development, providing form based entry of task attributes, and an animated display of task execution.

WSAD features Ant integrate by virtue of being built on the Eclipse tools platform.
