When you build a SNAPSHOT with an existing name (Guvnor shows you all the SNAPSHOTS and lets you select an existing one), the SNAPSHOT is updated (maybe under the hood the SNAPSHOT gets removed and a new one is created). So, if you have an application pointing to the SNAPSHOT you can update the assets it uses without modifying anything in the application itself.
The package snapshot wont be gone in the near future. One reason is
for backward compatibility. Another concern is that we still need to
find out if there are any use cases that package version can not
cover. In this case, your input is exactly what we are looking for.
Please see my comment in-line below.

Jervis, so you are trying to deprecate SNAPSHOTS in
favor of Versions? I don't think they address the same issue. With
SNAPSHOTS you can put different names to different "moments" of a
package.
We don't have this yet, but I guess this will be a very useful
feature. I.e. a named package version or package version alias.
More important, SNAPSHOTS were created and updated on
demand and not every time you update the package, so you can
update a SNAPSHOT definition adding or changing its assets and you
don't need to update your applications.
Not sure how you can do this? a SNAPSHOT is a read-only copy of
package. You can not change its configuration nor you can add or
change its asset.
They always read the package using same SNAPSHOT
name.
Using versions, I need to be careful in change my applications
when I want them to use some modifications I have in my package.
I mean, I also see package versioning as something good, but
I'm not sure if versions could replace SNAPSHOT. Are you
planning to add some way to put a name to a particular group of
versioned assets?
I have been able to use guvnor package versions
with some success..
Is there any service I can call to create a new
version? I have checked that it seems to change the
package version when you click on "save package".
Can I have some URL to achieve it automatically?
Hi,
Sorry for the late response, I was in holiday. There is no
REST service to create a package version as this is not
needed. A package version is created automatically when
your package gets updated (through Guvnor UI or through
REST).
Hi
everyone. I am using Guvnor
5.2, and I need to make some
operations from my
application.
Specifically, I need to
make two
operations remotely:
- List Snapshots, as it
is possible to list
packages.
- Create a new snapshot
from a package.
Is this possible to
make these operation
through rest API?
Hi,
Start from 5.3, Guvnor Packages
are fully versioned. I would
recommend you to use a vesioned
package instead of package
snapshot. Package snapshot will be
deprecated in the future.
