Re: [tycho-user] Tycho now supports alternative Target locations
That would be possible, the problem is only that such a target can be quite large.
If you think that you have a strong usecase for this I think it would be best added to the following ticket:

Hi,
wouldn't it now be nice if there was some tycho command to say "make this target local" ? and from that day on tycho uses the local definition that it cached somewhere (maven repo) 
of that specific target version?

this is now our target pom:

https://github.com/Servoy/servoy-eclipse/blob/master/launch_targets/pom.xml

i could add a profile there that would "localize" the target fully..
And from that moment on tycho uses the local target.

we do get a lot of these things:

and our target resolvement is taken quite some time for a lot of projects
So for me if tycho would have support now for getting a local (dir) target then it would be even nicer if that could be fully automated from a target definition 

Kind of what we now do in our local eclipse.
So all our developers are exporting that target file to there local disk and then have a special local.target pointing to that output and using that as the actual target in eclipse. Because it is very annoying that sometimes if there is a network problem developers are suddenly getting all kinds of problems because Eclipse decided to check the target and failed todo so.

    Until now it was only possible to use P2 based Update-sites with Tycho,
    from now on the other location types (Directory, Feature, Installation)
    are also supported.

    The feature is available in the up-comming 2.0 release line and as the
    feature is relative new it would be good if people can test the feature
    and give feedback if something is missing there.

    If using this feature the following things should be taken into account:

    * Because of the nature of file based locations you probably always
    wan't to include the target project in the reactor build when you
    reference files from that project as the reactor build is the only
    source for tycho to find 'projects'. The same applies if you reference
    other projects.
    * only a very small subset of the available variables are supported at
    the moment: Environment Variables, System-Properties and Project
    references, if you feel something essential is missing please open a
    bug
    so we can add support for this.
