IBM Clearcase plugin installation issue with Eclipse

Question

I am trying to install IBM Rational ClearCase SCM Adapter (For Eclipse), Version 7.6.0.0 following instructions on IBM site on Eclipse Juno CDT.

I am using Install New Software > Add with the following URL.

http://www3.software.ibm.com/ibmdl/pub/software/rationalsdp/clearcase/60/update/windows/

Installation fails with the following message

Cannot complete the install because one or more required items could not be found. Software currently installed: Rational ClearCase MVFS Support 7.6.0.v201105111445 (com.ibm.rational.clearcase.ccrefresh.feature.group 7.6.0.v201105111445) Missing requirement: Rational ClearCase Refresh Provider For MVFS Support 7.6.0.v201105111445 (com.ibm.rational.clearcase.ccrefresh 7.6.0.v201105111445) requires 'bundle org.eclipse.update.core 0.0.0' but it could not be found Cannot satisfy dependency: From: Rational ClearCase MVFS Support 7.6.0.v201105111445 (com.ibm.rational.clearcase.ccrefresh.feature.group 7.6.0.v201105111445) To: com.ibm.rational.clearcase.ccrefresh [7.6.0.v201105111445]

My question is : is this an issue of the plugin which does not support Eclipse Platform 4.X ? Or is there something wrong with my installation ?

For the record, the installation of the same plugin works correctly with Eclipse Indigo CDT.

Answer 1

I managed to solve this using the hints from Eclipse Help Site.

It's not a real issue with the plugin, but rather with the removal of the old Eclipse Update Manager APIs from Juno. What I did was to download an older Update Manager jar, drop it in the plugins folder, and them try the installation again. Now it works.

(One possible location for the download - Grepcode)

Answer 2

If you want to use a Clearcase plugin with Eclipse Juno or later (Kepler), the Open Source ClearCase plugin (not from IBM) works.

If you are a 64 bits user, it seems that Erez A. Korn's workaround does not work, so you have to fallback on another plugin.

Answer 3

Yes, it is a "Eclipse4.0 support" issue, as the official Eclipse versions supported for the IBM plugin are all 3.x.

Note that this isn't the only plugin suffering from this installation error message: the TeamCity plugin also get the same kind of error. (see TW-20759).
