helloWorld compilation error: package org.hipi.image does not exist #24

Open ecsho opened 8 years ago

ecsho commented 8 years ago

I'm using Hipi 2.1, Hadoop 2.6.0 and OpenCV 2.4.11. The simple helloWorld (i.e. just echo a message) could be built with gradle and executed successfully. However, the complex helloWorld (i.e. include map reduce function and import HIPI library in the top of the helloWorld program) is unable to build with gradle. The error messages state that org.hipi.image and org.hipi.imagebundle do not exist.

Pls. enlight how to diagnosis and fix this issue.

Hi, add compile files('libs/hipi-2.1.0.jar') to your dependencies in build.gradle file.

I am facing the same issue. Can anyone help me out here

mahekmerchant commented 8 years ago

add dependencies{ compile project(':core') }

ashishkumar4029 commented 7 years ago

you need to add dependencies in build.gradle file in your helloWorld project. Here is the code:

jar { manifest { attributes("Main-Class": "org.hipi.examples.HelloWorld") } dependencies{ compile project(':core')
} from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } } }

hope it works

I was facing the same problem @ashishkumar4029 : your solution worked for me. I am new to gradle and I do not understand it a much. can you please explain what this script means?
