I have an enhancement I offer to contribute, if this mail is going to
the wrong place i apologize and ask "Where should I send it?".
I have been looking for a good way to download an artifact from the
command line. dependency:get can put the file to my local repo or
optionally in a named file, but I want to get the file and retain
whatever name that file has.
I added code in the GetMojo to support a parameter to specify a
destination directory and one to optionally strip the version tag from
the file name. I didn't find any prior art for a test on the existing
destination parameter to copy paste so there is no test case =(
Attached is a svn diff of my change. It includes a version name change
to exclude my magic build from being overwritten if a real version 2.5.2
is released.
Cheers!
/ Andreas
