Lukas Theussl closed MAVEN-1623:
--------------------------------
Resolution: Fixed
> copyResources does not preservelastmodified
> -------------------------------------------
>
> Key: MAVEN-1623
> URL: http://jira.codehaus.org/browse/MAVEN-1623
> Project: Maven
> Type: Bug
> Environment: maven-1.0rc3
> Reporter: Matthias Kerkhoff
> Priority: Minor
> Fix For: 1.1-beta-3
>
>
> I noticed that whenever files are copied with the help of maven:copyResources
> the lastModified time is updated.
> This happens because the underlying ant copyTask is not
> called with preserveLastModified=true.
> (org.apache.maven.jelly.tags.maven.CopyResources, lines 109-137)
> While this is only annoying for me, I can easily imagine situations in which
> this behaviour will cause real problems.
> For example, commercial software often checks the last
> modified timestamp of some files.
> Actually, I digged into this because I tried to understand why some ears and
> rars in our project are constantly rebuild - even if we didn't change
> anything between the builds. So, fixing this (or adding an additional
> parameter to the tag) may also result in a performance gain.
