java - 运行 Ant 脚本时出现代理问题

Question

我正在为我的项目目的开发一个 Ant 脚本，并发现我的代理给我带来了问题。以下是 Apache 文档中“复制”任务的最简单示例:

=================== 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"/>
            </resources>
        </copy>
    </target>
</project>

我遇到了下一个错误:

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.

我尝试过设置

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

并在命令行中定义此属性

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

但遇到同样的错误:

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