Subject [jira] [Updated] (HDFS-2649) eclipse:eclipse build fails for hadoop-hdfs-httpfs

Jason Lowe updated HDFS-2649:

    Attachment: hdfs-2649.patch

I did a bit of investigation on this problem, and it appears to be a bug in the Maven Eclipse
plugin since version 2.7.  This problem may be fixed in version 2.9 (see http://jira.codehaus.org/browse/MECLIPSE-621).
 Unfortunately 2.9 still hasn't been released.

There have been plenty of discussions about how to workaround this issue.  One tactic is to
request version 2.6 of the Eclipse plugin rather than the latest (2.8).  That's what this
patch does, and it appears to work.  It does have the drawback that we'll have to remember
to remove this workaround at some point (e.g.: when 2.9 or later becomes generally available).

Another possible approach would be to place the filtered and unfiltered resources into separate
directories (e.g.: src/main/resources/filtered/ and src/main/resources/unfiltered/) but have
the build remove the extra directory level before depositing the resources into the target/
