can't update features in buckminster [message #554497]

Hi,

I have a working Buckminster installation that I use with Hudson. All nice and dandy. Alongside the normal Bucky features I need to install my own headless plugin, to do some custom build steps.

The problem is that now when I need to update my feature, I get an error:

Cannot complete the install because of a conflicting dependency.

[0.2]To: org.erlide.jinterface [0.8.2.201008231151]

I tried to uninstall the old version, doesn't work either (albeit silently).

What is the problem? (Can it be related to the fact that the update site where I installed from doesn't have that version available?)

What can I do to be able to update?

best regards,
Vlad

I tried this with a fresh buckminster and with a stable update site and it's the same: I can't update and I can't uninstall my feature...

There's no message in the log. What am I missing?

Hi Vlad,

do you happen to use nested features? As far as I know it is not
possible to update nested features, since the outer feature references a
concrete version of the contained features.
Do you use the automatic provisioning of the hudson plugin with a custom
json file? If so, have you tried simply deleting buckminster and let the
plugin install it again from scratch?

Best regards,
Johannes

Hi,

No, the headless feature is standalone. (It is included in the full SDK feature, but that one isn't used in this setting)

I use a standalone buckminster installation, because I had some problems with letting hudson install it.

Of course I can reinstall buckminster from scratch, but it feels like one should be able to update or uninstall the features. BTW, I tried to use the director app directly on the buckminster dir, but didn't work either (this may be caused by the wrong command line)

regards,
Vlad

How exactly did you try to update if not with the director? I'm not so
sure if the Buckminster install command is even able to do this. The
director should be the safer bet in any case...

You say maybe caused by the wrong command line? What did you try and
what was the response for that? Maybe I can help with fixing the
commandline if that turns out to be the problem.

Best regards,
Johannes

With 'buckminster install' and 'buckminster uninstall'. They should call the director under the hood, don't they?

> The director should be the safer bet in any case...

I managed to update with the director, but I still have to do uninstall first. (It didn't work at first because I had several versions of this feature installed, I had to uninstall all of them first).

It's working now, but it's highly unexpected. If I can update from the UI, I should be able to do it headless too, right?

Thanks for the help!

Vlad

The buckminster install and uninstall is originally based on the old
update manager and I don't think that it has the same functionality as
the p2 director.

Yes. But the director has no explicit update. An update is expressed by
-u installable.unit.id -i installable.unit.id
So uninstall + install in the same invocation. The director merges that
into an update operation.

Hope that helps

Yes, they do. But there is one difference. With the director, you can provide a whole slew of things to be installed in
one single command and they can be installed from several repositories. p2 will do one single plan and then install all
of it. With Buckminster install, the whole installation process is repeated for each thing that is installed so it's
generally much slower and sometimes less reliable. The end result should be the same but there are corner cases where p2
will make different decisions depending on how much it has access to.

Absolutely. The motivation for Buckminster install was to provide a smooth migration path when moving from the old
update manager to p2. It's still there because we don't want to break peoples builds but today it's just a very thin
layer on top of the director.

I definitely agree with Johannes. Use the director instead.
