build fails on mapreduce example project

[sialta]

When I try to run the example mapreduce program as said in getting started page I get this errors. Why?

[edureka@localhost hipi]$ cd examples/helloWorld/ [edureka@localhost helloWorld]$ gradle jar :examples:helloWorld:compileJava /usr/local/hipi/examples/helloWorld/src/main/java/org/hipi/examples/HelloWorld.java:3: error: package org.hipi.image does not exist import org.hipi.image.FloatImage; ^ /usr/local/hipi/examples/helloWorld/src/main/java/org/hipi/examples/HelloWorld.java:4: error: package org.hipi.image does not exist import org.hipi.image.HipiImageHeader; ^ /usr/local/hipi/examples/helloWorld/src/main/java/org/hipi/examples/HelloWorld.java:5: error: package org.hipi.imagebundle.mapreduce does not exist import org.hipi.imagebundle.mapreduce.HibInputFormat; ^ /usr/local/hipi/examples/helloWorld/src/main/java/org/hipi/examples/HelloWorld.java:24: error: cannot find symbol public static class HelloWorldMapper extends Mapper<HipiImageHeader, FloatImage, IntWritable, FloatImage> { ^ symbol: class HipiImageHeader location: class HelloWorld /usr/local/hipi/examples/helloWorld/src/main/java/org/hipi/examples/HelloWorld.java:24: error: cannot find symbol public static class HelloWorldMapper extends Mapper<HipiImageHeader, FloatImage, IntWritable, FloatImage> { ^ symbol: class FloatImage location: class HelloWorld /usr/local/hipi/examples/helloWorld/src/main/java/org/hipi/examples/HelloWorld.java:24: error: cannot find symbol public static class HelloWorldMapper extends Mapper<HipiImageHeader, FloatImage, IntWritable, FloatImage> { ^ symbol: class FloatImage location: class HelloWorld /usr/local/hipi/examples/helloWorld/src/main/java/org/hipi/examples/HelloWorld.java:25: error: cannot find symbol public void map(HipiImageHeader key, FloatImage value, Context context) ^ symbol: class HipiImageHeader location: class HelloWorldMapper /usr/local/hipi/examples/helloWorld/src/main/java/org/hipi/examples/HelloWorld.java:25: error: cannot find symbol public void map(HipiImageHeader key, FloatImage value, Context context) ^ symbol: class FloatImage location: class HelloWorldMapper /usr/local/hipi/examples/helloWorld/src/main/java/org/hipi/examples/HelloWorld.java:30: error: cannot find symbol public static class HelloWorldReducer extends Reducer<IntWritable, FloatImage, IntWritable, Text> { ^ symbol: class FloatImage location: class HelloWorld /usr/local/hipi/examples/helloWorld/src/main/java/org/hipi/examples/HelloWorld.java:31: error: cannot find symbol public void reduce(IntWritable key, Iterable values, Context context) ^ symbol: class FloatImage location: class HelloWorldReducer /usr/local/hipi/examples/helloWorld/src/main/java/org/hipi/examples/HelloWorld.java:46: error: cannot find symbol job.setInputFormatClass(HibInputFormat.class); ^ symbol: class HibInputFormat location: class HelloWorld /usr/local/hipi/examples/helloWorld/src/main/java/org/hipi/examples/HelloWorld.java:53: error: cannot find symbol job.setMapOutputValueClass(FloatImage.class); ^ symbol: class FloatImage location: class HelloWorld 12 errors :examples:helloWorld:compileJava FAILED
