问题
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.
回答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)

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.
回答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).
回答4:
ClearTeam Explorer which comes with version 8 of clearCase should have no problem with Juno
回答5:
The org.eclipse.update.core JAR can be copied over to the eclipse instance's plugins directory from the IMShared\plugins directory to resolve the issue.
