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,
 
Miles

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,
 
Miles

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

[p2-dev] RE: Metadata generator app creates metadata that causes IUinstallation to fail

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.

Miles

[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: 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
