Unable to import project into eclipse

[albe91]

hi,
i followed the guide and tried to import the project into eclipse (Kepler before and Luna after),but after selecting the unzipped folder librec-v1.1 or librec.v1.0 it says that no project has been detected.
Neither it is possible to run the jar file from command line since it gives the following error:

Exception in thread "main" java.lang.NullPointerException
at happy.coding.io.Configer.getPath(Configer.java:41)
at librec.main.LibRec.debugInfo(LibRec.java:248)
at librec.main.LibRec.main(LibRec.java:70)

If i'm doing something wrong please tell me!
Thanks for the patience
AF

Hi AF,

The released version does not include the source code. That's why you cannot import project from the unzipped folder librec-v1.1 or -v1.0. The tutorial says to download the source code (http://www.librec.net/tutorial.html#setup). The latest source code can be download as a zip, or a specific version of source code can be download via https://github.com/guoguibing/librec/releases.

The librec libraray requires a configuration file, "librec.conf" by default. According to your exceptions, make sure the data set path is in right format:

ratings.wins=D:\path\to\dataset\ratings.txt
ratings.lins=/home/user/ratings.txt

The formats can be found in http://www.librec.net/tutorial.html#develop

You are right, i didn't read carefully the instructions, my bad!
Thanks a lot and sorry to have bothered you!

[guoguibing]

Can you show me your settings?

[guoguibing]

The path settings should be like below:

ratings.wins=D:\path\to\dataset\ratings.txt
ratings.lins=/home/user/ratings.txt

[albe91]

This is the path
################################################### General Settings #############################################
###dataset: item ratings and user social inforamtion
dataset.training.wins=D:\path\to\dataset\ratings.txt
dataset.training.lins=/Users/SmokingRooster/Documents/train.txt

[guoguibing]

Note that in windows, the path should be separated by "\" rather than ""

I'm on Mac os x

It seems that the OS detection has a bug. I'll fix it up later.

[albe91]

No problem sir!

[guoguibing]

I do not have a mac. Can you try to replace with the new dependent library: https://github.com/guoguibing/librec/tree/master/librec/lib

Now it's working, thanks for the support!
