RE: [p2-dev] RE: Metadata generator app creates metadata thatcauses IU installation to fail
|
Pascal - would it be possible for the metadata generator to
validate the generated metadata on completion? The timestamp in this case
resulted in a reference that could not be resolved. Is this kind of thing is
detectable?
Let me know and I will raise a bugzilla issue.

Thx for the update and detailed data set. Still I'll dig a bit to figure out
what is going on.

RE: [p2-dev] RE: Metadata generator app
creates metadata that causes IU installation to
fail |
I have found the apparent source of
the problem: the org.apache.ivy plugin. The version in the site at the moment is
2.0.0.cr2, however in the plugin MANIFEST.MF seemed wrong: Bundle-Version:
2.0.0.cr2_20081028224207. I edited this to Bundle-Version: 2.0.0.cr2, reran the
metadata generator and hey presto: everything installed perfectly.
Thoughts?Thanks,MilesMiles

Subject: RE: [p2-dev] RE: Metadata
generator app creates metadata that causes IU installation to fail
1. The IvyDE site (e.g.
http://mirrors.ukfast.co.uk/sites/ftp.apache.org/ant/ivyde/updatesite) is a legacy site. So the mirror app is generating
metadata for it. 2. I can install other IUs into my eclipse install without error.
There are
lots of differences between the 2 sets of metadata. So many that it would be
better to let it speak for itself, so I have attached the files to this mail.
Would you mind taking a look? I would be interested to know what you
think.Thanks,MilesMiles

Two questions:
- Do you know if the IvyDE update site is a p2
repository or a legacy update site?
- If you try to install IvyDE and then
you try to install something in that installation, do you get the same
error?
I'm suspecting that the problem here is with the fact that p2 does
not have the complete metadata when installing from a p2 update site.
Did you
try to see what was the difference in the two
metadata?
Thx

[p2-dev] RE: Metadata generator app creates metadata that
causesIUinstallation to fail |
The
basic point here is that, when I mirror the IvyDE update site I get meta data
that allows me to install the Apache IvyDE and Apache Ivy features. If I
generate metadata for the site using the p2 metadata generator app then I get
metadata that causes installation to fail. Does anyone know why this might be
and why the 2 operations result in different metadata? Is different code being
used in each case?
Why do I care? Because I need to create a large, mixed
mirror based on stuff from update sites across the planet. This one problem
means that I may need to create a separate internal repo just for IvyDE since
the only way to get viable p2 meta for it is a straight mirror. This is not very
convenient.
Thanks,
Miles

If anyone has read
this message and you need more information I will happily provide
it.
As
a workaround I tried copying the mirrored metadata (which works - allows me to
install Apache Ivy and Apache IvyDE) into the build directory. I then ran the
metadata generator over the result in append mode hoping that it would merely
add metadata to the initial set. Unfortunately it rewrote the sections on the
Apache IUs and resulted in metadata that caused installation of the Apache Ivy
IU to fail.
Thanks.

Subject: [p2-dev] Metadata
generator app creates metadata that causes IU installation to fail
Hi All,
I have run into a problem whilst
trying to mirror the Apache IvyDE site. Here are the steps to
reproduce:
1. Mirror http://www.apache.org/dist/ant/ivyde/updatesite using mirror apps from 3.5M3 as per these docs:
http://wiki.eclipse.org/Equinox_p2_Repository_Mirroring
2. Try
installing both IUs from mirror into vanilla 3.4.1 install:
success.
3. Uninstall both IUs from 3.4.1
4. Discard mirrored
metadata and generate using the metadata generator app (also from 3.5M3) as
per these docs: http://wiki.eclipse.org/Equinox_p2_Metadata_Generator
5. Try
installing both IUs from the resulting mirror (with new metadata): install
fails with the following error:
Unsatisfied dependency:
[org.apache.ivy.feature.feature.group 2.0.0.cr2] requiredCapability:
org.eclipse.equinox.p2.iu/org.apache.ivy/[2.0.0.cr2,2.0.0.cr2]
Unsatisfied
dependency: [org.apache.ivy.feature.feature.group 2.0.0.cr2]
requiredCapability:
org.eclipse.equinox.p2.iu/org.apache.ivy/[2.0.0.cr2,2.0.0.cr2]
I do not know how to interpret this error but it seems to me
that there is some kind of circularity occurring here. Does anyone have any idea
what is going wrong and where?
Thanks,
Miles
