熟悉ant的帮忙看下，执行这个build.xml时一直报错，connection time out

背景是：项目的jar包升级，从ibatis2升级到mybatis3，我从google code下载了这个build文件，搭建了ant环境，但是用ant编译的时候报错，connection time out。请大家帮忙看看，谢谢

1.ant环境应该没错

2.开始执行

3.报错：

4.看下文档目录

请各位大牛帮忙看下，多谢了

执行 ANT -V查看详细信息

:oops: 这个build.xml怎么这么复杂？？？？？

这个链接超时是不是某些下载链接无法链接下载啊？？？

I'm trying to run a build script which has a target that uses the
task and references an external <xmlcatalog>, but Ant is giving me the warning message below. Apache resolver library not found, internal resolver will be used Warning: catalogpath listing external catalogs will be ignored I've Googled a lot about this problem and couldn't find any helpful information, except this thread: <a href="http://www.ant-tasks.com/msg/14363.html">http://www.ant-tasks.com/msg/14363.html</a> </blockquote> Hello, I got the same error message today and solved it. So I am posting some comments on this issue for the archive: The original author's problem has been probably caused by the fact that he was using xml-commons-resolver-1.0 in the classpath. The Ant documentation explicitly mentions that you should use xml-commons-resolver-1.1: <a href="http://ant.apache.org/manual/CoreTypes/xmlcatalog.html">http://ant.apache.org/manual/CoreTypes/xmlcatalog.html</a> My own problem was caused by myself having put the correct version of resolver.jar into JDK's jre/lib/endorsed directory (because I upgraded Xalan and it appeared to pick it up all right from there). For some reason, if resolver.jar is visible to the classloader for jre/lib/endorsed, Ant will not be able to use it, EVEN if you add it to the Ant classpath.
