FileNotFountException for intro.csv in mahout userBasedCF recommendation

[Dulakshi Vihanga]

I created a maven project and in the pom file I added the following
dependency

<dependency>
        <groupId>org.apache.mahout</groupId>
        <artifactId>mahout-mr</artifactId>
        <version>0.11.0</version>
    </dependency>

I followed the example in mahout in action and added the RecommenderIntro
class to src/main/java and copied the intro.csv file into src/main/resource
folder.

Error occurs in:

*DataModel model = new FileDataModel (new File("resources\intro.csv"));*
Exception in thread "main" java.io.FileNotFoundException: resources/intro.csv

org.apache.mahout.cf.taste.impl.model.file.FileDataModel.<init>(FileDataModel.java:180)

    at 
org.apache.mahout.cf.taste.impl.model.file.FileDataModel.<init>(FileDataModel.java:147)
    at recstest.UserBased.main(UserBased.java:19)

I also copied the file to main src\main\java and checked and still the
same error occurs.
What could be the reason for this?
