Todd Lipcon commented on HADOOP-6671:
-------------------------------------

Cool stuff, Alejandro! A few things I noticed while trying this out locally:

- nit: The project name is "Hadoop Common" rather than "Hadoop Commons"
- I'm getting errors for our usage of the com.sun.javadoc stuff - eg:
{code}
/home/todd/git/hadoop-common/src/main/java/org/apache/hadoop/classification/tools/ExcludePrivateAnnotationsJDiffDoclet.java:[42,16]
 cannot access com.sun.javadoc.Doclet
class file for com.sun.javadoc.Doclet not found
    return JDiff.start(RootDocProcessor.process(root));
/home/todd/git/hadoop-common/src/main/java/org/apache/hadoop/classification/tools/RootDocProcessor.java:[55,12]
 cannot find symbol
{code}
Is this the bit where I need to add a softlink? Any workaround for this we can 
do local to the project?

- "mvn test" seems to be dumping all the log to stdout. Is there a way to get 
it to log just to the files like ant used to?
- is there an equivalent of our "bin-package" target which makes a tarball but 
doesn't build the forrest docs?
- the assembly doesn't seem to build if I choose not to compile native:
{code}

[INFO] ------------------------------------------------------------------------
[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------
[INFO] An Ant BuildException has occured: 
/home/todd/git/hadoop-common/target/native/lib does not exist.
{code}

> 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.
