Subject [jira] Commented: (HADOOP-6671) To use maven for hadoop common builds
Date Fri, 02 Apr 2010 20:27:28 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6671?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12852939#action_12852939

E. Sammer commented on HADOOP-6671:

So much of the build system today "acts as" maven it might as well be maven. Having some consistency
in the way the individual projects are built would be extremely nice. Maven is as painful
as every other build tool we've seen but at least its pain comes in a consistent, known, quantity.
The tooling support tends to be better due to the predictable nature of the the build process.
The surrounding infrastructure (such as Hudson) is already mvn aware. The main problem with
mvn tends to be errant dependencies in poms but this can be avoided (see the SpringSource
Ivy / Maven repositories for an example of *very* well maintained metadata - http://www.springsource.com/repository/app/).

>             Project: Hadoop Common
>          Issue Type: Improvement
>          Components: build
>    Affects Versions: 0.22.0
>            Reporter: Giridharan Kesavan
> We are now able to publish hadoop artifacts to the maven repo successfully [ Hadoop-6382]
> Drawbacks with the current approach:
> * Use ivy for dependency management with ivy.xml
> * Use maven-ant-task for artifact publishing to the maven repository
> * pom files are not generated dynamically 
> To address this I propose we use maven to build hadoop-common, which would help us to
manage dependencies, publish artifacts and have one single xml file(POM) for dependency management
and artifact publishing.
> I would like to have a branch created to work on mavenizing  hadoop common.
