我们有一个可通过 HTTP 访问的 Ivy 存储库。它可以被多台机器毫无问题地访问，但在 Windows 机器上，我们会收到服务器访问错误。

现在没有涉及防火墙或代理，并且可以使用其他工具（例如，浏览器、curl、wget ......）毫无问题地访问 URL。例如：

$ curl http://ivy.ethz.ch/checkstyle/checkstyle-all/5.5/ivy-5.5.xml
<ivy-module version="2.0">
    <info organisation="checkstyle" module="checkstyle-all" revision="5.5" status="integration" publication="20120806133612"/>
        <publications>
                <artifact name="checkstyle-all" type="jar" ext="jar"/>
        </publications>
</ivy-module>

在服务器端，日志什么也没有显示：没有错误，甚至没有连接

编辑 ivysettings.xml应该没问题，因为它们可以在 Mac OS X 和 Linux 上毫无问题地使用：

<ivysettings>
    <settings  defaultResolver = "ETHZ-HTTP" >
        <caches defaultCacheDir = "${ivy.settings.dir}/ivy-cache" />
    </settings>
    <resolvers>
        <url name="ETHZ-HTTP">
            <ivy      pattern="http://ivy.ethz.ch/[organisation]/[module]/[revision]/[artifact]-[revision].xml" />
            <artifact pattern="http://ivy.ethz.ch/[organisation]/[module]/[revision]/[artifact]-[revision].[ext]" />
        </url>
    </resolvers>
</ivysettings>

有什么提示吗？

也许你的 Windows 机器上有一个防火墙阻止 Java 做任何网络？

试试这个简单的 ant build.xml 文件来测试它：

<project>
    <get src="http://ivy.ethz.ch/checkstyle/checkstyle-all/5.5/ivy-5.5.xml" dest="ivy-5.5.xml" />
</project>
