Re: [tycho-user] Subproject produces "eclipse-repository" packaging, but Eclipse instance fails to install referenced plugin

By connecting a debugger to the target eclipse instance, I was able to determine that this was caused by a handful of corrupted jars in my $HOME/.p2 repo. I've submitted an enhancement request to add the full path of the corrupted zip file to the exception. I now need to know the exact surgery I need to make to the corrupted jars in $HOME/.p2 to fix this. I would guess that I would just delete them and let Eclipse redownload them, but I'm not going to guess on this. I've asked that question in my original PDE forum post, but does anyone know the answer to that question?

looks like some signed content was corrupted.
This could be either your bundles/features (if you happen to sign them) or external dependencies of it.

Check the eclipse error log if there are any details about which file is corrupted.
You may also try to mirror your p2 repo [1], this should validate it (possibly in debug mode using -X maven CLI switch).

I inherited a largish Eclipse plugin codebase

Now I'm attempting to install the built update site in an existing
Eclipse instance.  I've tried defining the update site in Eclipse by
selecting the "update-site/target/<basename>.zip" from the "Archive"
button, and also "update-site/target/repository" from the "Local" button.

When I select this update site in "Install New Software", I'm able to
select the one feature, then click "Finish" on the "Install Details"
page, but the next page always reports this:
An error occurred during the
org.eclipse.equinox.internal.p2.engine.phases.CheckTrust phase.
session context was:(profile=_home_opnfv_eclipse_java-neon_eclipse,
operand=, action=).
Error reading signed content.
error in opening zip file

The other curious, and perhaps telling, symptom is that on the "Install
Details" page, when it lists the plugins to be installed, there is a
block below which has a "Size:" label.  This says "0 bytes".  I don't
know what this indicates, if anything.

I'm not familiar with the required structure of an update site, so I
don't know what might be wrong.  Maven doesn't complain when it builds
this module.

What else can I look at to diagnose this?
