[jira] Commented: (HADOOP-3302) Support Maven-based builds

["Hiram Chirino (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-3302?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12617103#action_12617103 ] 

Hiram Chirino commented on HADOOP-3302:
---------------------------------------

1) While maven is more exposed to malicious repository attacks due to it automatically getting dependencies, that same attack can affect someone if they download dependencies manually.  Hopefully maven one day will provide a better signature checking facility.
2) Agreed dependencies of the final distro need to be manually checked but this should be getting done regardless.  This does not mean that build time dependencies all need to be ASL compatible, jut the run time and distribution artifacts.
3) Once again this one affects any repo, not just maven repo users.

So I'm hoping that artifact signature checking becomes an option in maven day.

> The reasons I would like to use maven are:
> - the possibility to define artifact templates to define a kind of standard layout/design by artifact
> - it is not necessary for every developer to come up with his own ant build-file and process
> - the possibility to define and resolve dependencies transitively
> But there are also some disadvantages/concerns I identified:
> Maven is downloading a lot of plugins from a central repository that is not under my control
> - What's about the licenses of these plugins? How do I know I am allowed to use them for a commercial product?
> - What's about security? How can I be sure, that the plugins are not manipulated and contain the original (delivered by the JAR provider for e.g. junit-jar) contents. I observed, that some plugins didn't pass the md5 checks but have been installed anyway.
