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

Andariel is a set of tasks designed to help the generation of HTML (and other markup languages) pages from Ant. Includes a XPath processor, an image information retriever, and others.

AntDoc is a tool that generates HTML documentation from Ant buildfiles; the generated HTML is inspired from what javadoc yields. AntDocGUI offers a simple Ant target launcher named AntDoc GUI. Ant targets may be launched from the generated AntDoc HTML pages. Integration to various IDEs is in progress.

AntDoc can be run via an Ant task, AntDoc GUI can be run via an Ant task, or via a JVM launch.

Anteater is a set of Ant tasks for the functional testing of websites and web services (functional testing being; hit a URL and ensure the response meets certain criteria). Can test HTTP params, response codes, XPath, regexp and Relax NG expressions. Includes HTML reporting (based on junitreport) and a hierarchical grouping system for quickly configuring large test scripts.

Provides simple inheritance between ant files

Ant Pretty Build is a tool to show and run Ant buildfiles directly from within a browser window. It consists of a single XSL file that will generate, on the fly, from buildfile, a pretty interface showing project name, description, properties and targets, etc. allowing to run the whole project, or run selected targets in a specific order.

Timer is task for measuring the time elapsed to complete other tasks

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.

ChownTask is an Ant task to change ownership of files on Unix.

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.

CMSDeploy is an Apache Ant Task to submit files and templates to Vignette CMS.

This task allows the generation of static web pages and sites using Apache Cocoon in off-line mode.

It allows the configuration information for Cocoon to be included within the Ant build file, and is thus able to take advantage of Ant properties.

The task shares its code with the Cocoon Command Line, which means that this task will instantly take advantage of any new functionality added there.

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.

Dependency Finder extracts dependencies and OO metrics from Java class files produced by most Java compilers. It can compute API differences between versions; no sources needed. It includes Ant tasks, web, Swing, and command-line interfaces, with XSL stylesheets for formatting output.

You can use it to extract dependencies between packages, classes, or even methods, or any combination thereof. You can use Perl regular expressions to filter the information and pinpoint only what you need. There is even a Web Application version (WAR file) so a whole group of developers can share a common view.

There are two Ant tasks for running the Doxygen documentation system.

FMPP is a general-purpose text file preprocessor tool that uses FreeMarker templates. It is particularly designed for HTML preprocessor, for the generation of complete (static) homepages: directory structure that contains HTML-s, image files, etc. But of course it can be used to generate source code or whatever text files. FMPP is extendable with Java classes to pull data from any data sources (XML file, database, etc.) and embed the data into the generated files.

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

Greebo is an Ant-task for downloading dependency files (currently only jars) from a network to a specified directory, much like Maven. It supports multiple local and remote repositories with either flat or maven-like structures. It can read the dependency list from a Maven project file, a maven-like dependency file, or directly from the build.xml file.

The CodeCoverage sub-project of GroboUtils provides a 100% pure Java code coverage tool. It uses pre-execution class file recompilation, and generates XML files containing the coverage statistics. It does not require any advanced VM setup to generate coverage numbers.

idldepend is a task that (re)generates Java sources to be created from CORBA/IDL files.

It parses the IDL file and determines the Java files that must be generated, taking in account the modifications that can happen due to command line parameters. If any of the Java files are missing or older than the source IDL specification, it launches the specified compiler. The compilers of Orbacus, Jacorb, OpenORB, Orbix2k and Sun'JDK distributions are supported.

To speed up the process and avoid unnecesary re-parsing, it keeps the dependencies in intermediate files. This task does not launch the javac compiler as well, that is, its output are Java files and not the final bytecode.

Image task generates and transforms images. It exposes the imaging capability available in Java2D, Java Advanced Imaging, ImageIO, etc., as set of nested elements.

Image transformations such as "resize" (scale),"overlay" (one image on another), "border" (add a border), "text" (text on image), "crop" (a sub-image of a bigger image), "rotate", "grayscale" (change a color image to shades of gray).

Removes unnecessary import statements from a Java source code file.

ImTask is a task to allow one to send an Instant Message. Currently supports yahoo!, AIM, and Jabber

Task allowing to run a dialog within a build used to setup some properties. This way you can fill a property with the input of a user.

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

There are four 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:

Antenna provides a set of Ant tasks suitable for developing wireless Java applications targeted at the Mobile Information Device Profile (MIDP). With Antenna, you can compile, preverify, package, obfuscate, and run your MIDP applications (aka MIDlets), manipulate Java Application Descriptor (JAD) files, as well as convert JAR files to PRC files designed to run on MIDP for Palm OS. Deployment is supported via a deployment task and a corresponding HTTP servlet for Over-the-Air (OTA) provisioning. A small preprocessor allows to generate different variants of a MIDlet from a single source.

Antic is a freely available task for packaging J2ME applications. It produces both the Jar and Jad files in a single step. This allows *all* entries to be correclty set in the jad file, including the size of the jar file that is produced. This task has been used and tested extensively with Sun's Wireless Toolkit and also the Nokia SDK and emulators.

Jacson is a configurable and plugable tool (much like Ant itself) to create filters for text (line based) files without programming.

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

Java+ is an open source Java preprocessor that adds these features to any Java compiler:

• Multi-line strings with executable inclusions like Perl and Ruby. It eliminates the need for JSP or ASP and their need for Java compilers on deployment servers (a security concern) while adding no overhead in either space or time.
• Optionally supports localization by segregating Java+ strings into ResourceBundle files with invarient keys based on the hash code of the strings's value. This is handled automatically and transparently; no intervention is required.
• Fast. Negligible impact on build times. By default, skips inputs whose outputs are up to date to avoid triggering recompilations.
• Pure Java code, portable to any platform, with graphical, shell and ant interfaces.
• Simple, general, recursive, digraph-driven string syntax. Digraph characters are user-selectable.

There are two different tools both named Java2HTML that process Java source code and generate syntax higlighted documentation from it. Both include Ant tasks to run them.

It works from the command line or using several provided Ant tasks.

JMX4Ant provides tasks for integration with JMX (Java Management Extensions). It provides tasks for getting and setting attributes of MBeans, invoking their methods and much more.

JNI is a free toolkit that makes easy work of integrating Java and C through the Java Native Interface (JNI). It includes a code generator that generates both Java "proxy" classes to access C "peer" classes, and C "proxy" classes to access Java "peer" classes or interfaces. It also includes a core library with a simplified JVM interface as well as "helper" classes to ease working with the JNI data types. The code generation is driven by an XML project file that can be created with the assistance of the GUI Project Manager. The code generation can be invoked either from Ant or from the GUI. Includes a comprehensive printable PDF User Guide and plenty of examples.

JRun 4 SP1 ships with lib/jrun-ant-tasks.jar, which defines three Ant tasks: jrun, jrunapp, and jrunjmx. Documentation for the tasks can be found in JRun under docs/ant/jrun.html.

Note that the service pack must be installed on top of an existing JRun 4 installation.

• Feedback(log4j,jlog,etc.),
• Flowcontrol(templates),
• and Helpers.

Kanaputs is a parser for java based scripting. It is an interpreter for Java. With Kanaputs you can use Java as an interpreted language: no more compilation, each instruction is executed when you write it. It is a small programmation language to make script files above Java.

Kanaputs Ant Task provides a way to add any kind of programmatic features in your Ant script. The code you insert stays OS independent (because Kanaputs uses Java) and is completely integrated with Ant as you can give Ant properties to the Kanaputs code and get back the results in other properties.

Moreover, as you can invoke any kind of Java code with Kanaputs, you can popup windows from your Ant file to ask the user to do a choice.

The mtxslt (Multi-XSLT) extends the standard Ant "xslt/style" task to make it easy to use multiple XSLT engines during the same build. This is useful for regression testing of XSLT scripts against several engines.

pack is a task to build the smallest possible JAR to link and run one or more classes.

Pamda is an MDA tool (UML2Code generator) implemented as Ant task. Pamda supports Aspect-Oriented Modeling (AOM) and comes with AOM UML Profile and sample project. The tool uses XMI as its input and Velocity as template engine. All elements in the metamodel have navigate(XPath expression) and iterate(XPath expression) (powered by JXPath) which make templates easy to write.
Tested with XMI produced by Enterprise Architect.

PCT is a task to compile Progress code, and in a more general way, to deal with Progress procedures and databases.

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

PRes is short for Property Resources and will generate a Java source file from name=value pair .property files which can be compiled like any other class.

ProGuard is a free Java class file shrinker and obfuscator. It can detect and remove unused classes, fields, methods, and attributes. It can then rename the remaining classes, fields, and methods using short meaningless names.

Purge deletes all but the most recent few files from a fileset. For example: if you have generated files (logs, .ear, .war, .jar etc) accumulating in a directory, the purge task will allow you to delete the older files, keeping just the most recent ones.

The collections contain 3 Tasks for simplifying application deployment: sfx creates native self extracting executables out of ZIP archives; jstub creates native executables; jnlp simplifies the creation of JNLP files for Java Web Start.

A task designed to help with the single-sourcing of program documentation. Rundoc replaces special commands (in the format @@rundoc:command param1 param2...@@) embedded within text files with their output in a specified format. Currently, only Docbook format is supported.

Rundoc was written to keep sample code output in program documentation synchronized with the actual output of the current code, by running the referenced code when the documentation is built.

SerialVer adds the Java serialver functionality to Apache Ant. This project adds Tasks and FilterReaders to get, to insert and to modify the serialVersionUID in the source code of a serializable class.

Simian (Similarity Analyser) identifies duplication in Java, C#, C, CPP, COBOL, JSP, HTML source code and even plain text files.

Powerful analysis of dependencies between Java classes. Only affected classes will be recompiled and it can be used with any bytecode compiler.

A task designed to help with the single-sourcing of program documentation. Snip extracts snippets of text from files, placing them into properties in the Ant project. These properties can then be used by any other Ant task, and are particularly useful when referenced by <filter>s within the <copy> task.

Snip was originally written to keep snippets of sample code in API documentation synchronized with the actual sample classes.

A text-to-speech task and build listener, which produce voice output either to speakers or .wav file (the task only).

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.

Transforms source files into HTML documents with syntax highlighting. It can handle a variety of source files including Java, HTML, C/C++, SQL, and Java properties. Colors for elements are specified using cascading style sheets. The output can be templated for easy integration with a site's look and feel.

The TestSetGenerator is an ant task for generating property files with testsets based on the results of SQL queries and validation plug-ins. Very usefull when building unit tests that make use of changing datasets. This task is an extension of the Ant SQL task. Hsqldb is used for both the examples and the unittests.

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.

WSDLValidate is available as an Ant task, an Eclipse plug-in and a command line utility.

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.

XInclude is a W3C standardized vocabulary for including arbitrary text or XML documents in other XML documents. This task perfomes the inclusion using an existing XInclude implementation

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

yGuard is a free Java(TM) Bytecode Obfuscator Task that needs no external script or project files. It can completely be configured and run through the Ant build script. The task supports multiple Jar files at once and makes use of patternsets and regular expressions to specify elements, which should be left unobfuscated. Additionally it can be used to produce patches for obfuscated applications that have already been deployed.
