Ant is
the standard build tool used by most open source Java projects and is widely being used in commercial
settings as well. You need Ant version 1.4 or latter. You can download the 1.4 binaries for Ant from <a href="javascript:if(confirm('http://jakarta.apache.org/builds/jakarta-ant/release/v1.4/ \n\nThis file was not retrieved by Teleport Pro, because it is addressed on a domain or path outside the boundaries set for its Starting Address. \n\nDo you want to open it from the server?'))window.location='http://jakarta.apache.org/builds/jakarta-ant/release/v1.4/'" tppabs="http://jakarta.apache.org/builds/jakarta-ant/release/v1.4/" target="_top">this link to the Apache/Jakarta website</a>. If you have problems finding
binaries at that location try the Ant home page which is located <a href="javascript:if(confirm('http://jakarta.apache.org/ant/index.html \n\nThis file was not retrieved by Teleport Pro, because it is addressed on a domain or path outside the boundaries set for its Starting Address. \n\nDo you want to open it from the server?'))window.location='http://jakarta.apache.org/ant/index.html'" tppabs="http://jakarta.apache.org/ant/index.html" target="_top">on the Apache/Jakarta website</a>.</p><p>Once you have the Ant distribution unarchive it to create a jakarta-ant-1.4 directory. The Ant documentation
is located in the docs/manual directory. You should start with the docs/manual/index.html file and browse through its
contents if you want to use Ant. You won't need to know anything about Ant build scripts in order to compile and run
the examples in the JBoss documentation. All we care about at this point is that you have Ant installed and availble
in your executation path such that you can run ant from the command line. To do this you need the path to the jakarta-ant-1.4/bin
directory in your PATH environment variable(or the equivalent construct for you OS). So for example, I have Ant installed
in /usr/local/Java/Ant/jakarta-ant-1.4 and my PATH contains /usr/local/Java/Ant/jakarta-ant-1.4/bin. On a win32 platform
with Ant installed in G:/tmp/jakarta-ant-1.4 you would need G:/tmp/jakarta-ant-1.4/bin in your PATH. Setup your
PATH now.</p><p>You need the bin directory of a 1.3 JDK(Java development kit) in your path as well for access to the
java interpreter and java compiler. You also typically need to set the JAVA_HOME environment variable to point to
the location of a JDK 1.3 installation so that Ant can find the javac compiler. Your Ant installation may have been
configured such that this is not necessary and you can try the following installation test without this set at first.</p><p> Test the Ant installation by opening a shell or command prompt. Next create a build.xml file in the
current directory that contains the contents listed in the following figure:<div class="figure"><p><a name="d0e177"></a><b>Figure 1.1. Ant build.xml script for testing an Ant installation</b></p><div class="literallayout"><br>
<!-- Simple Ant build script to test an Ant installation --><br>
<project name="TestInstall" default="run" basedir="."><br>
<br>
<target name="init"><br>
<available file="ASimpleHelloObject.java" property="ASimpleHelloObject"/><br>
</target><br>
<br>
<target name="ASimpleHelloObject" unless="ASimpleHelloObject" depends="init"><br>
<echo file="ASimpleHelloObject.java"><br>
public class ASimpleHelloObject<br>
{<br>
public static void main(String[] args)<br>
{<br>
System.out.println("ASimpleHelloObject.main was called");<br>
}<br>
}<br>
</echo><br>
<echo message="Wrote ASimpleHelloObject.java" /><br>
</target><br>
<br>
<target name="compile" depends="ASimpleHelloObject"><br>
<javac destdir="." srcdir="." debug="on" classpath="."><br>
<include name="ASimpleHelloObject.java"/><br>
</javac><br>
</target><br>
<br>
<target name="run" depends="compile"><br>
<java classname="ASimpleHelloObject" classpath="." /><br>
<echo message="Ant appears to be successfully installed" /><br>
</target><br>
<br>
</project><br>
</div></div>
</p><p>On a linux system with the build.xml file in /tmp you should see output like:<div class="literallayout"><br>
<tt>bash-2.04$ ant<br>

<br>
init:<br>

[echo] Ant appears to be successfully installed<br>
<br>

<br>
Total time: 2 seconds</tt><br>
</div>On a win32 system with the build.xml file in D:/temp you should see output like:<div class="literallayout"><br>
<tt><br>

</div>If instead out see something like:<div class="literallayout"><br>
<tt><br>
D:\temp>ant<br>
<br>
Warning: JAVA_HOME environment variable is not set.<br>
If build fails because sun.* classes could not be found<br>
you will need to set the JAVA_HOME environment variable<br>
to the installation directory of java.<br>

BUILD FAILED<br>

D:\temp\build.xml:22: Cannot use classic compiler, as it is not available A comm<br>
on solution is to set the environment variable JAVA_HOME to your jdk directory.<br>
<br>
Total time: 1 second<br>
</tt><br>
</div>then you need to setup the JAVA_HOME environment to point to your JDK 1.3 installation.</p></div><table border="0" cellpadding="0" cellspacing="0" height="65"><tr height="65"><td rowspan="2"><img src="gbar.gif" tppabs="http://www.huihoo.org/jboss/online_manual/3.0/gbar.gif" width="432" height="79"></td><td rowspan="2" background="gbar.gif" tppabs="http://www.huihoo.org/jboss/online_manual/3.0/gbar.gif" width="100%" align="right" valign="top"><a href="index.html" tppabs="http://www.huihoo.org/jboss/online_manual/3.0/index.html"><img src="doc.gif" tppabs="http://www.huihoo.org/jboss/online_manual/3.0/doc.gif" border="0"></a><a href="ch01.html" tppabs="http://www.huihoo.org/jboss/online_manual/3.0/ch01.html"><img src="toc.gif" tppabs="http://www.huihoo.org/jboss/online_manual/3.0/toc.gif" border="0"></a><a href="ch01.html" tppabs="http://www.huihoo.org/jboss/online_manual/3.0/ch01.html"><img src="prev.gif" tppabs="http://www.huihoo.org/jboss/online_manual/3.0/prev.gif" border="0"></a><a href="ch01s06.html" tppabs="http://www.huihoo.org/jboss/online_manual/3.0/ch01s06.html"><img src="next.gif" tppabs="http://www.huihoo.org/jboss/online_manual/3.0/next.gif" border="0"></a></td></tr><tr></tr></table></body></html>⌨️ 快捷键说明
