'FeatureNotFoundException: Feature 'bigData' not found' error when open SVN project

[TalendSolutionExpert]

Problem Description

Opening an existing SVN project in Talend Studio, results in the following error message:

The Studio error log displays the following message:

!ENTRY org.talend.platform.logging 2 0 2018-08-23 10:27:04.344
!MESSAGE 2018-08-23 10:27:04,344 WARN org.talend.commons.exception.CommonExceptionHandler - org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1DiagnosticWrappedException: org.eclipse.emf.ecore.xmi.FeatureNotFoundException: Feature 'bigData' not found.

Root Cause

This issue may happen when opening an existing project with a higher version of Talend, for example, opening a Talend 5.6 project in Talend 6.4. Opening the project in a higher version generates new binaries that might conflict with the existing ones.

Solutions

To resolve this issue, go back to the SVN project that wasn't changed for the higher version of Studio, by performing the following steps:

1. Identify the version you want to go back to.
2. Dump that revision into a new dump file.
3. Load the new dump file into a new repository.
4. Replace the old repository with the new repository.
