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.

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'.

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.

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.

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.

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.

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.

A plugin that integrates Ant into the jEdit editor.

An OpenTool that integrates Ant into the JBuilder IDE.

A plugin that integrates Ant into the Jext editor.

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.

Anthill is a build tool that promotes a controlled build process by ensuring that every build reflects the source repository contents and tagging the repository with a unique build number after every build. Anthill also encourages the sharing of knowledge within an organization by automatically updating a project intranet site with artifacts from the latest build.

CruiseControl is a tool for setting up a continuous build process. CruiseControl provides an Ant wrapper and a set of tasks to automate the checkout/build/test cycle. CruiseControl also comes bundled with a servlet for viewing the status of the current build, as well as previous build results.

XML Publication is a set of tools to generate Web pages from desktop documents or other structured documents using XSLT and Ant.
