搞了两个晚上了，protoc --version返回正确，jdk版本也是1.7，在protobuf-2.5.0下mvn package也是成功的

谢谢你的回复，我在ubuntu下执行mvn eclipse:eclipse -DskipTests能成功，但是在win7 64位下还是报那个错，请问在win下我需要装cygwin吗？

请问需要安装cygwin吗？

自己顶一下，楼主，请问碰到过这种情况吗？

jdk版本太低，使用jdk1.7

终于解决了，是由于jdk的版本问题，我的win7是64位的，装的32位的jdk，换成64位的jdk就好了

用maven编译完成后，hadoop-2.4.0-src的大小 还是90多M，感觉没下完全啊！d:/1.png,没看到share目录，没有jar包啊？？这是为什么

pig2  大神留个QQ啊，有问题想请教你啊  我的是824884219

学习了，总结的不错

jdk的版本必须在1.6以上

博主，请问我用hadoop2.6.0,
（注意的是，我们这里是引入的是编译包，编译的下载hadoop--642.4.0.tar.gz

那这个还可以用么？？？
