For example, suppose you want to install support for netrexx, which jpackage does not support: Decide where you want to deploy the extra jars.

Another, less messy option is to create an. More information on where Ant finds its libraries is available here Download a non-jpackage binary distribution from the regular Apache Ant site Unzip or untar the distribution into a temporary directory Copy the linking jar, in this case ant-jai.

Advanced There are lots of variants that can be used to run Ant. What you need is at least the following:. To build Ant from source, you can either install the Ant source distribution or checkout the ant module from SVN.

See Source Edition for details. See Installing Ant for examples on how to do this for your operating system. It does not work with gcj or kjc. Make sure you have downloaded any auxiliary jars required to build tasks you are interested in. Note that this will make the auxiliary JAR available for the building of Ant only. You can also get most of the auxiliary jar files ie.

See Optional Tasks for instructions on how to do this. As of version 1. The fetch. On most occasions you will not need to explicitly bootstrap Ant since the build scripts do that for you. If however, the build file you are using makes use of features not yet compiled into the bootstrapped Ant, you will need to manually bootstrap.

Run bootstrap. Ant's build script will try to set executable flags for its shell scripts on Unix-like systems. There are various reasons why the chmod-task might fail like when you are running the build script as a different user than the one who installed Ant initially. In this case you can set the Ant property chmod. The following libraries are needed in Ant's classpath if you are using the indicated feature.

Note that only one of the regexp libraries is needed for use with the mappers and Java includes a regexp implementation which Ant will find automatically. You will also need to install the particular Ant optional jar containing the task definitions to make these tasks available. Note : Ant 1. Note : BSF 2. Ant has a built in diagnostics feature.

If you run ant -diagnostics ant will look at its internal state and print it out. This code will check and print the following things.

Running ant -diagnostics is a good way to check that ant is installed. It is also a first step towards self-diagnosis of any problem. Any configuration problem reported to the user mailing list will probably result ins someone asking you to run the command and show the results, so save time by using it yourself.

This can be added to a diagnostics target in a build file to see what tasks are available under the IDE, what the XML parser and classpath is, etc. If you cannot get Ant installed or working, the Ant user mailing list is the best place to start with any problem.

Try the IDE mailing lists first, who will cross-file bugs if appropriate. IDEs can invariably be pointed at different Ant installations. This lets developers upgrade to a new release of Ant, and eliminate inconsistencies between command-line and IDE Ant. Many Java applications, most particularly application servers, ship with a version of Ant.

Such distributions are usually unsupported by everyone. Particularly troublesome are those products that not only ship with their own Ant release, they add their own version of ANT. BAT or ant. If Ant starts behaving weirdly after installing something, try the diagnostics advice. If you prefer the leading-edge code, you can access the code as it is being developed via Git.

The Ant website has details on accessing Git. All bug fixes will go in against the HEAD of the source tree, and the first response to many bug reports will be "have you tried the latest version". Don't be afraid to download and build a prerelease distribution, as everything other than new features are usually stable.

See the section Building Ant on how to build Ant from the source code. You can also access the Ant Git repository on-line. The files are organized as follows. The platforms used most for development are, in no particular order, Linux, macOS, Microsoft Windows and Unix; these are therefore that platforms that tend to work best. Since Ant 1.
