Leiv Hellebo commented on MJBOSS-59:
------------------------------------
with the new patch it is possible to do the following for a project with
<fileNames>
<fileName>my-ds.xml</fileName>
<fileName>mywar.war</fileName>
</fileNames>
$ mvn jboss:unpack
# change some .xhtml files, this doesn't require full redeploy, so best not
# to touch my-ds.xml and mywar.war/WEB-INF/web.xml .
$ mvn jboss:unpack
# then change some JPA entity, which requires rebuilding of a persistenceunit,
# this will be triggered by a redeploy so
$ mvn jboss:unpack -Djboss.overwrite=true
> Make unpack not overwrite existing files if there are no changes

> Currently the HardDeployMojo overwrites all destination files, even if there
> are no new changes to those files.
> It would be very nice if e.g. web.xml for web-apps was not overwritten unless
> a newer version was available. This would allow resources like .xhtml-files
> and .class-files to be redeployed without triggering a full redeploy of the
> application when the web.xml file is unmodified.
> The attached patch modifies unpack(zipFile,targetDir) to check file
> timestamps and avoids overwriting existing targets unless newer sources are
> available.
> Similar changes to copyFile(src,dst) would perhaps be interesting, but
> without, say a
> /**
> * @parameter default-value="true"
> */
> boolean overwrite
> it will make "mvn jboss:hard-deploy" no longer trigger a redeploy of the
> fileName(s).
> (Indeed this patch will of course, if applied, also remove the
> redeploy-side-effect doing a jboss:hard-deploy. But then that is the whole
> point of this patch. The redeploy-side-effect should rather be had through
> other means, say a new goal hard-redeploy.)
