[p2] no SDKProfile generated when building eclipse from source [message #112058]

I am trying to build eclipse from source, but the result does not have
any SDKProfile or generated p2 metadata. The way I understand it, the
build script should be generating the p2 metadata. Is this a correct
assumption? If so, where in the eclipse build scripts is the call to
generate the metadata or where is the configuration set for generating
this metadata? I see the generate.p2.metadata targets in the
assemble.org.eclipse.sdk.os.win.arch.xml and
package.org.eclipse.sdk.os.win.arch.xml files but I do not see how the
if="generate.p2.metadata" conditional is ever set.
Thanks for any help.

This never received a reply and I would also like to know the answer. I
know that Tim hasn't found the answer yet. I can generate the
metadata but I'm still missing an SDKProfile.

I noticed that the generated content.xml is very much like an
SDKProfile so I tried taking the <units> element from that but some
stuff was missing. In particular, any references to org.eclipse.sdk.ide
and so nothing appeared under Installed Software. Obviously this isn't
the right way to do it anyway.

Taking the SDKProfile from the official tarball kinda works but it
doesn't quite match my build so that isn't really the answer either.
What is the correct way to generate it?

Regards,
James

So I eventually realised that you have to use the P2 director
application to install as well as generating the metadata. The
SDKProfile stuff is now present.

However, there is still a problem. I run P2 director as root as it is a
multi-user installation. When each user runs Eclipse, their own copies
of bundles.info and source.info do not get created. The missing
source.info is a problem because unless I copy it manually, Eclipse
does not see any of the source plugins and tries to install them the
first time I use the Update Manager. If I use the Classic Update
Manager, I see lots of red Xs with messages about plugins not being
available at runtime.

I could copy these files manually in a wrapper script but a proper
solution would be nice. Aren't the files supposed to be copied
automatically?

Regards,
James

Hi James,
Someone left a great comment on my blog yesterday with instructions for
generating the SDKProfile (2 java commands). I have since tested the
instructions (substituting different names for Gentoo) and am now
happily using p2 for my solaris-gtk-x86 distribution. The blog entry is
here; just look for Chewi's comments at the bottom:

I hope this helps!

Haha. If you look at my e-mail address, you'll notice that was me. (-;
I didn't notice this other problem till after I posted the comment.
Maybe you ran the P2 director application as the same user that you're
running Eclipse as? It would probably work okay in that case.

James

Hmm I've noticed something interesting. If I use the prebuilt tarball
of Eclipse (in this case, linux-gtk-x86_64), as long as the
installation is not writable by the user running Eclipse, the exact
same problem occurs. So it's not a problem with the way we're building
Eclipse. Maybe I should file a bug?

Hi James,
Good to put a name with a handle. I had not noticed your email address....
Anyway, this is an interesting use case, and you are quite right that I
was running eclipse and the p2 director as the same user. I will keep
an eye out for this.
Thanks again.
