There is no hard and fast rule, but typically the property file is named as build. You could create multiple build properties files based on the deployment environments - such as build. The contents of the build property file are similar to the normal java property file. They contain one property per line. Each property is represented by a name and a value pair.
It is highly recommended that the properties are annotated with proper comments. Comments are listed using the hash character. The following example shows a build. In the above example, sitename is a custom property which is mapped to the website name. You can declare any number of custom properties in this fashion. See the next section for examples.
Here is the result of a search through the codebase. Because system properties are available via Project instance, I searched for them with a. After that I filtered out the often-used but not-so-important values most of them read-only values : path. If new properties get added it happens , expect them to appear under the ant. Accordingly, please avoid using properties that begin with these prefixes. This protects you from future Ant releases breaking your build file.
Ant start up scripts in their Windows and Unix version return the return code of the java program. So a successful build returns 0 , failed builds return other values. Setting a system property when invoking Ant is not straight forward as the corresponding command line arguments must be sent to the Java executable rather than Ant's main class. When using the ant. Starting with Ant 1. As this is a normal Ant property it can be set via the command line or even from within a build file.
Tasks and types using the temporary directory will state the fact inside of their respective manual page. In addition every execution of an external command on OpenVMS will create a temporary file holding a DCL script that invokes the actual command. Tasks not provided with the Ant distribution will ignore the ant. Security Note: Using the default temporary directory specified by java.
This is especially true in multi-user environments. It is recommended that ant. Ant 1. Unix launch script that come with Ant works correctly with Cygwin. You should not have any problems launching Ant from the Cygwin shell.
It is important to note, however, that once Ant is running it is part of the JDK which operates as a native Windows application. You can use an executable name such as sh and rely on that command being available in the Windows path. It has two parts: ant. Most often you will just call ant. The behaviour can be modified by a number of ways explained below.
Script ant. The requirements are:. If any of these conditions is violated, script antenv. This script first invokes configuration scripts if there exist: the system-wide configuration antconf.
Finally ant. All settings made by ant. 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. For the current version of Ant 1. The more up-to-date the version of Java, the more Ant tasks you get.
Note : Ant 1. The Ant team strongly supports users running Ant on OpenJDK and other open source Java runtimes, and so strives to have a product that works well on those platforms. To install Ant, choose a directory and copy the distribution files there. Note that current releases of Ant no longer support these systems. This is due to limitations in the OS's handling of the "for" batch file statement. It is recommended, therefore, that Ant be installed in a short , 8.
On these systems you will also need to configure more environment space to cater for the environment variables used in the Ant launch script. To do this, you will need to add or update the following line in the config. Before you can run Ant there is some additional setup you will need to do unless you are installing the RPM Version from jpackage. Note that using this method, the settings will only be valid for the command line session you run them in. Note : Do not install Ant's ant.
Ant is an application, whilst the extension directory is intended for JDK extensions. In particular there are security restrictions on the classes which may be loaded by an extension. The ant. You can check the basic installation with opening a new shell and typing ant. You should get a message like this. So Ant works. This message is there because you need to write a buildfile for your project. With a ant -version you should get an output like. If this does not work, ensure your environment variables are set right.
JDK is recommended as some tasks require the Java tools. PATH is set for user convenience. Ant supports a number of optional tasks. An optional task is a task which typically requires an external library to function. The optional tasks are packaged together with the core Ant tasks. The external libraries required by each of the optional tasks is detailed in the Library Dependencies section.
These external libraries must be added to Ant's classpath, in any of the following ways:. This makes the JAR files available to all Ant users and builds. This allows different users to add new libraries to Ant.
All JAR files added to this directory are available to command-line Ant. On the command line with a -lib parameter. This lets you add new JAR files on a case-by-case basis. Avoid this; it makes the JAR files visible to all Java applications, and causes no end of support calls. See below for details. Where possible, this option is generally to be preferred, as the Ant script itself can determine the best path to load the library from: via relative path from the basedir if you keep the library under version control with your project , according to Ant properties, environment variables, Ivy downloads, whatever you like.
If you are using the binary distribution of Ant, or if you are working from source code, you can easily gather most of the dependencies and install them for use with your Ant tasks. This is an Ant script that you can run to install almost all the dependencies that the optional Ant tasks need. You may also need to set proxy settings.
See the Proxy Settings section for details. Note that not all dependencies are gathered using fetch. Tasks that depend on commercial software, in particular, will require you to have the commercial software installed in order to be used. The Apache Ant Project also provides additional tasks and types that are available as separately downloaded Ant Libraries.
