Shellscript for installing CDT into Eclipse SDK

Eclipse SDK BuildID: I20090313-0100 (3.5m6)
CDT BuildID: 6.0.0M6-200903161435
Host OS: Tested on linux-gtk and windows XP

I'm running a little shellscript to call p2 director in order to install CDT (from its zipped Repository) into the Eclipse SDK.

My p2 commands is basically the same as referenced in the Docs:
   http://127.0.0.1:16775/help/topic/org.eclipse.platform.doc.isv/guide/p2_director.html

with the one exception that I do not pass in a -version argument. This was not necessary in previous builds -- the script ran successfully with m4 and m5; and, I do not know where to obtain a proper version. Thus I'm assuming that the -version argument is optional, and/or documentation is missing for the p2 director -version argument. My command is (full shellscript attached):

./eclipse/eclipse -nosplash \
  -data install-ws -consolelog -clean \
  -application org.eclipse.equinox.p2.director.app.application \
  -metadataRepository file:${curdir}/install-source/ \
  -artifactRepository file:${curdir}/install-source/ \
  -installIU org.eclipse.cdt.feature.group \
  -vmargs \
    -Xms128M -Xmx256M -XX:PermSize=128M -XX:MaxPermSize=256M 

and the failure generated by p2 director is:

I can confirm that the workaround of adding

  -destination (absolutePath)/eclipse

works. I did not manage to install into a separate extension location that way, which would be link via a *.link file from dropins/ -- but I might not have tried hard enough.

The -version argument turned out not to be necessary. I suggest marking it as optional in the docs. Do you need a separate bug for this?

- p2 does not deal with extension location as target of an installation. This is the famous extension location discussion. I think you are cc'ed on it.

- please open a bug for the doc.  thx
