> Refactor HAMA POM
> -----------------
>
> Key: HAMA-382
> URL: https://issues.apache.org/jira/browse/HAMA-382
> Project: Hama
> Issue Type: Improvement
> Components: build , examples
> Affects Versions: 0.2.0
> Reporter: Tommaso Teofili
> Assignee: Tommaso Teofili
> Fix For: 0.3.0
>
> Attachments: HAMA-382.patch
>
>
> Refactoring include:
> Change the groupId to not include the 'incubator' and replace it with 'hama'
> as the 'incubating' suffix is already added to the artifact version and the
> artifactId to 'hama-core', thus the resulting artifact would be
> org.apache.hama/hama-core/$version-incubating.
> Create a profile 'examples' to generate the hama-examples jar with Maven
