A quick test of condition elements in ant

ant-condition-test.xml

<project name="condition-test" default="all">
    <target name="condition">
        <condition property="isTomcat">
            <matches pattern="^(tomcat)" string="${webContainer}" />
        </condition>
        <condition property="isWebLogic">
            <matches pattern="^(web)" string="${webContainer}" />
        </condition>
    </target>

    <target name="all" depends="condition">
        <echo message="the value of webContainer is ${webContainer}"/>
        <echo message="isTomcat = ${isTomcat}"/>
        <echo message="isWebLogic = ${isWebLogic}"/>
    </target>
</project>

# Test:
$ ant -f ant-condition-test.xml -DwebContainer=tomcat
Buildfile: /Users/jeff.johnson/dev/ant-condition-test.xml

condition:

all:
     [echo] the value of webContainer is tomcat
     [echo] isTomcat = true
     [echo] isWebLogic = ${isWebLogic}
