Issue with proxy while running Ant script

I'm developing an Ant script for my project purposes and figured out that my proxy causes problem for me. Here is the simplest example from Apache documentation of 'copy' task:

=================== build.xml =====================
<project default="simplestCopy">
    <property name="test.dir" value="${basedir}/test/" />

    <target name="simplestCopy">
        <mkdir dir="${test.dir}" />
        <copy todir="${test.dir}" flatten="true">
            <resources>
                <url url="http://ant.apache.org/index.html"/>
            </resou开发者_如何转开发rces>
        </copy>
    </target>
</project>

I've got next error:

d:\temp>ant
Buildfile: d:\temp\build.xml

simplestCopy:
java.net.ConnectException: Connection refused: connect

BUILD FAILED
d:\temp\build.xml:7: Warning: Could not find resource url "http://ant.apache.org/index.html" to copy.

I've tried to set kind of

<property name="java.net.useSystemProxies" value="true" />

And define this property in command line

d:\temp>ant -Djava.net.useSystemProxies=true -verbose

But got same error:

d:\temp>ant -Djava.net.useSystemProxies=true -verbose

Any ideas how to fix?

Thanks for help...

Use the setproxy task: http://ant.apache.org/manual/Tasks/setproxy.html

I started the tomcat server and then issue the command and it works
