Cannot checkout as local project in Talend 6.4.1

[Anonymous]

Hi , 

I was trying to checkout git branch as local , but failing due to below error, 

org.eclipse.core.runtime.CoreException: Cannot open the project.Error task is org.talend.repository.model.migration.MigrationTaskFortOleDbCoseConnection.

Interestingly , I could checkout some other branches but for specific branch I just failed, 

I have tried with new workspace location, but got the same issue, 

Git credential are working fine.

Really need help,

Hello,

Is your specific branch corrupted? Have you tried to create a new project in TAC, setup as desired and Import items into the new project once opened to restore to the last state of your Git project?

Would you mind creating a case on talend support portal so that we can give you a remote assistance by using webex session through support cycle with priority?

Best regards

Sabrina

After lot trials/test , I could figure out the issue, 

Issue was due to Talend version upgrade,

Recently I had a upgrade Talend 6.4.1 to Talend 6.5.1 and I did committed some job changes to same git branch and I was trying to load same branch into old Talend 6.4.1, 

Talend not being backward compatible cost me 2 days of time  

Cheers,
