一个开源项目bamboo，用了一个Oceanstore项目的类生产了jar作为lib，现在我需要修改oceanstore里面的类来使得bamboo支持ipv6,在原来jar文件里面，Nodeid,相关的类包含了四个class文件：:NodeId$1.class, NodeId$BadFormat.class, NodeId$Both.class，NodeId.class文件，而我现在下来Oceanstore源码，修改后编译只有两个calss文件，NodeId$BadFormat.class，NodeId.class。我用这两个文件运行jar -uf 更新jar里面的这两个文件，在运行bamboo程序就出了错误。。
我的问题是：
NodeId$1.class和odeId$Both.class是什么意思，编译源代码为什么没有两个文件产成，
而且我这种直接更新jar文件，是因为其他两个nodeid类文件的.class没有更新出现的问题，还是其他原因使得运行发生错误
在bamboo的lib里面有makefile文件，是不是更新里面的lib要使用make命令呢，为什么我使用是提示 Nothing to be done for `all'我该怎么去融合两个开源项目呢，重新编写makefile有太麻烦，这么直接更新又出现错误。下面是NodeId.java 文件和lib里面的makefile文件package ostore.util;

名字里有$的是内部类，也就是包含在NodeId中的。你改的类里没有这些内部类，当然就不生成了。你的代码太乱了，我是没兴趣看。csdn提供了java的语法着色，为什么不用呢？？
