ant如何编译nutch2.x？
我下载的是nutch2.1 ，看很多网上的教程都是1.x的版本；我在官网上看到 1.x不需编译，而2.x则不行，要用ant编译(至少网站上是这么说的)
然后我安装了ant，在编译的时候有问题了。
2.x的目录结构下直接是 conf,doc,lib,src,build.xml等
而在src下才有一个运行需要的bin目录
我进到解压完的根目录，直接ant (里面有build.xml)
运行一下就卡住了，里面的信息片段：

--------------------编程问答-------------------- 和你相同问题
--------------------编程问答-------------------- 求高手帮忙解决呀，那个什么缺少的包我也已经导入了。还是没有用，不是因为那个原因！！！！ --------------------编程问答-------------------- 不是卡住了，是[ivy:resolve] :: loading settings :: file = /home/appmon/release-2.2.1/ivy/ivysettings.xml这里要花一点时间联网检测，等一会就会继续，大约2-5分钟，如果很久没有反应，则Ctrl+C结束，再重新运行ant。 --------------------编程问答-------------------- 楼上说的对，等一会就行了。 --------------------编程问答-------------------- loading之后报错呢？为什么会提示module not found呢？

这个问题可以通过下载sonar的jar包，并将jar包放到相应的路径，放路径的话可以直接修改build.xml文件，在里面找到org/sonar/ant/antlib.xml，然后在classpath中修改jar的位置。
至于卡在那里不动的问题，确实是网络的问题，需要耐心等一会
如果无易做图常下载jar包，有时是因为无法连接中央仓库所导致的，可以换个地址试试，可以参考这篇博客
