[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.

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
