[jira] Reopened: (HADOOP-6267) build-contrib.xml unnecessarily enforces that contrib projects be located in contrib/ dir

Todd Lipcon reopened HADOOP-6267:
---------------------------------


I disagree. This is simply better ant style, and the technique is a specific example on the ant import task documentation:

http://ant.apache.org/manual/CoreTasks/import.html

Part of the ASF principles and the choice of the Apache license is to encourage outside contributions. While this has no positive (or negative) effect on the project build itself, it makes it easier to develop code that will later be contributed, and encourages that development to be tightly coupled to the existing build process. This means there will be less work later to add it as a contrib/ project, which is good for everyone involved.

Do you have any specific complaints about the patch? If it is zero-sum for the existing codebase but positive for future contributions, it seems to me like it's a net win.

> build-contrib.xml currently sets hadoop.root to ${basedir}/../../../. This path is relative to the contrib project which is assumed to be inside src/contrib/. We occasionally work on contrib projects in other repositories until they're ready to contribute. We can use the <dirname> ant task to do this more correctly.
