Use p2 Install Repository v4.0.x for existing Eclipse installation via links folder

We used to install the Rational Team Concert client into a supported version of Eclipse via link folder and pointing to the p2 Install Repository files.
We are still on RTC v2.0.0.2 and our current configuration is (kinda): 
.
`--  eclipse
   `-- links
       `-- RTC.link
where the 'RTC.link' file is set to use the content of RTC-Client-p2Repository-2.0.0.2iFix6.zip.
We are preparing to migrate to RTC v4.0.7 and if we set the 'RTC.link' file to use the content of RTC-Client-p2Repo-4.0.7.zip, we are not able to use this approach anymore: 
!ENTRY org.eclipse.equinox.p2.engine 4 4 2015-04-15 17:01:16.064

Any advice?
Thanks in advance.

In fact, we found we are able to update some of our Eclipse based IDEs (e.g., IBM RSA) and not others (e.g., Genuitec MyEclipse). So, it could be a missing reference problem for some "base" plug-ins...

This is a curious case - I can see the same issue with the RTC 4.0.6 p2 package.

In the root folder of the package, there should be two files artifacts.jar and contents.jar, but artifacts.xml and contents.xml (unpacked) are there instead. This simple fact seems to confuse the Eclipse p2 installer. Simply compress these two files into the respective .jar files, and move the .xml files somewhere else, and the problem is gone.

We notice these two files are unpacked even in the older p2 repository: 
RTC-Client-p2Repository-2.0.0.2iFix6
|-- features
|-- license
|-- plugins
|-- artifacts.xml
`-- content.xml

The only difference with the new one seems to be a binary folder: 

RTC-Client-p2Repo-4.0.7
|-- binary
|-- features
|-- license
|-- plugins
|-- artifacts.xml
`-- content.xml
Anyway, we will give your suggestion a try:

Thanks for the advice, Donald.

I remember seeing a notification saying that it worked but later you edited the post and said it did not work. So what happened? I tested with RTC 4.0.7 p2 package with a RTC 3.0.1.1 client (the oldest I could find) and managed to upgrade it without major issues - just had to restart the RTC Eclipse client twice to finish the installation.

Sadly, it was a false positive result (due to a mistaken configuration).

We are not going to update an existing RTC client. Instead, we would install/use the RTC client plug-ins in all our Eclipse based IDEs.

We tried Donald's trick: 
$ cd RTC-Client-p2Repo-4.0.7
$ jar cf artifacts.jar artifacts.xml && rm artifacts.xml
$ jar cf content.jar content.xml && rm content.xml
but it did not work... The error message now is:

You will need to be very specific about the configuration that is having the issue. I just tried with plain Eclipse 3.5, and only part of the RTC components got installed and I had a perspective called "Jazz Administration". Strange, right?

On IBM RSA v8.5 we could observe the RTC client plug-ins appear to be present, but in fact the log lists:

I forgot to mention, there is no common Eclipse version that is officially supported by both RTC 2.0.0.x and RTC 4.0.7. So your current Eclipse version does make a (huge) difference. My tests showed that Eclipse 3.5.2 (RTC 3.0.1) still works, but Eclipse 3.5 fails.

SEC Servizi commented Apr 24 '15, 9:13 a.m.

We are updating the RTC version as well as the Eclipse IDE.
