Ant: How to set Environment Variables Using Ant - ant

Question

I have environment variables in a file called release.com as follows,
echo "<<< OpenSplice HDE Release V5.5.1OSS For x86.linux2.6, Date 2012-05-23 >>>"
if [ "$SPLICE_ORB" = "" ]
then
SPLICE_ORB=DDS_OpenFusion_1_6_1
export SPLICE_ORB
fi
if [ "$SPLICE_JDK" = "" ]
then
SPLICE_JDK=jdk
export SPLICE_JDK
fi
OSPL_HOME="/usr/local/covidien/HDE/x86.linux2.6"
OSPL_TARGET=x86.linux2.6
PATH=$OSPL_HOME/bin:$PATH
LD_LIBRARY_PATH=$OSPL_HOME/lib:$LD_LIBRARY_PATH
CPATH=$OSPL_HOME/include:$OSPL_HOME/include/sys:$CPATH
OSPL_TMPL_PATH=$OSPL_HOME/etc/idlpp
OSPL_URI=file://$OSPL_HOME/etc/config/ospl.xml
. $OSPL_HOME/etc/java/defs.$SPLICE_JDK
CLASSPATH=$OSPL_HOME/jar/dcpssaj.jar:$CLASSPATH
CLASSPATH=$OSPL_HOME/jar/dcpscj.jar:$CLASSPATH
export CLASSPATH OSPL_HOME OSPL_TARGET PATH LD_LIBRARY_PATH CPATH OSPL_TMPL_PATH OSPL_URI
$#
and i will use this environment variables in Linux as,
# source release.com
Using Ant script how to set release.com as source ?

To add to Mark's answer, Ant XML build files may also be used to centralize your dependencies in external files.
dependencies.xml
<project name="deps" basedir=".">
<dirname property="deps.basedir" file="${ant.file.deps}"/>
<property name="my.jar" location="${deps.basedir}/my-tasks.jar" />
<taskdef name="my-ant-task" classpath="${my.jar}"
classname="org.my.domain.ant.MyAmazingTask" />
</project>
build.xml
<project name="my-project" basedir=".">
<import file="dependencies.xml" />
<target name="give-my-task-a-spin">
<my-ant-task />
</target>
</project>
If you have a large number of custom tasks, it a good idea to place them in an antlib, which can reduce memory usage by sharing the same class loader for all the tasks in the library.
<antlib>
<taskdef name="my-task01"
classname="org.my.domain.ant.MyCustomTask01" />
<taskdef name="my-task02"
classname="org.my.domain.ant.MyCustomTask02" />
<taskdef name="my-task03"
classname="org.my.domain.ant.MyCustomTask03" />
...
</antlib>
