[jira] Commented: (MDEP-154) dependency:copy always creates new timestamp, when copying from Repository to local filesystem

    [ http://jira.codehaus.org/browse/MDEP-154?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=205577#action_205577 ] 

Philippe Bourgau commented on MDEP-154:
---------------------------------------

Hi,

We are having exactly the same issue with unpack-dependencies. The consequence is that dependencies get unpacked once again, even if they did not change. This slows the build down, and as we are using unpack-dependencies for our dev builds, it is really annoying.

How to reproduce:
It is easier to reproduce the problem with the global updatePolicy option set to always. Suppose that the dependencies did not change in your global repository. When running unpack-dependencies:

 1 - in your local repository the dependencies get a new timestamp (strange, no real download, it's just a touch)
 2 - the metadata for the dependencies in the local repo do not change
 3 - the dependencies are unpacked for nothing
 4 - the markers for the unpack-dependencies are not updated (this seems weird according to point 3)

Thank you,

Philippe
