在Ubuntu中使用Nut 1.4

Question

I try to use nutch 1.4 crawler in ubuntu however when I try to execute nutcg with all the setting that are suggested in nutch wiki it gives this error:

erogol@erogol-G50V:~/Desktop/search engine/apache-nutch-1.4-bin/runtime/local$

Program will exit.

Do you have any suggestion or idea to solve the using problem for nutch?

Thanks in advance... all nutch knowers :)

Answer 1

The problem isn't about nutch: the space within the search engine folder name creates problems. As you can see from the ClassNotFoundException the part after the space is taken as name of the class to be executed. Can't you just rename search engine to something else like search-engine ?
