Subject [jira] Commented: (HDFS-830) change build.xml to look at lib's jars before ivy, to allow overwriting ivy's libraries.
Date Wed, 16 Dec 2009 19:46:18 GMT

    [ https://issues.apache.org/jira/browse/HDFS-830?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12791547#action_12791547

Konstantin Boudnik commented on HDFS-830:
-----------------------------------------

I've converse with Aaron in offline and he had shared how he does common testing in his setup.
Here's the main idea (and it is fully supported by our current mechanism):
{noformat}
  common% ant jar mvn-install
  hdfs% ant veryclean test -Dresolvers=internal
{noformat}
The idea is that first command installs fresh Common artifacts to the local maven repository.
The second command then wipes out old version from Ivy cache and use the internal maven repository
to obtain the needed snapshots.

I've checked it and it works like a chime. So, I'd suggest to drop proposed the modification
all together and update an appropriate Wiki page with this information if it isn't already
done.

> Currently build.xml looks first into ivy's locations ,before picking up jars from lib
directory.
> We need to change that to allow overwriting ivy's libs with local ones, by putting them
into lib.
