This post covers the steps to fix the Eclipse error “Incompatible file format. Workspace was saved with an incompatible version: 0” or any other tool based on top of Eclipse, be it DBeaver, BMIDE, Anypoint Studio, KNIME or any other.
The steps to fix this error are pretty much same for any application built on top of Eclipse.
Being a developer is sometimes painful when there are errors in the development tool itself. Abd the first place of troubleshooting for a developer is the log file. Let’s open the log file mentioned in the error.
java.lang.Exception: Incompatible file format. Workspace was saved with an incompatible version: 0.
org.eclipse.core.internal.resources.ResourceException: Incompatible file format. Workspace was saved with an incompatible version: 0.
The above error appears while opening Eclipse and does not open Eclipse.
The simplest way to fix “Incompatible file format. Workspace was saved with an incompatible version: 0.” error in Eclipse is to delete the org.eclipse.core.resources under <WORKSPACE_PATH>\.metadata\.plugins folder.
Fix for “Incompatible file format. Workspace was saved with an incompatible version: 0.”:
To fix the error, there are two easy ways.
1. Delete org.eclipse.core.resources folder
Go to <WORKSPACE_PATH>\.metadata\.plugins and look for the plugin folder named org.eclipse.core.resources
Delete or rename this folder and try to open Eclipse again.
Eclipse creates this org.eclipse.core.resources plugin folder again and opens fine. In most cases, this should fix the error. In case, you are still facing the issue, follow point #2.
Note: After the corrupted org.eclipse.core.resources folder is deleted, you need to reimport the project to the workspace.
2. Create a new workspace
Create a new workspace on the Eclipse launch screen by selecting the Browse... button and choosing another folder than your current workspace.
That’ it and the eclipse error "Incompatible file format. Workspace was saved with an incompatible version: 0." while launching Eclipse will not be there anymore.
Cheers!!!
