Can not open Knime workflows nor create new workflows after migration to a new Drive

KNIME Analytics Platform
1

Basically the title.
Additionally I get this error:

java.lang.IllegalAccessError: tried to access method org.knime.core.node.workflow.WorkflowContext$Factory.(Lorg/knime/core/node/workflow/WorkflowContext;)V from class org.knime.core.node.workflow.WorkflowManager
Here is the log:

knime.log (3.0 MB)

Could you give us a little more context (system, what new drive) and maybe you delete the log and try to start KNIME again so we might have a look at the core information.

Then you might try a -clean restart once, and make sure no additional instances of KNIME are run and you have access to your knime-workspace.

KNIME start with -clean option in knime.ini

Hi @mlauber71,

I am using Windows and exchanged my HDD with a SSD.

EDIT: I tried it with the clean option and it still shows the same error.

Do you use Dropbox or Microsoft OneDrive for your knime-workflow.

You should make sure all three of your meta folders are accessible

  • the folder where the KNIME program is (you can just create a new one with a fresh version)
  • The knime-worspace folder where all your workflows are which is the most important one and should not be corrupted
  • The folder where KNIME stores the temporary files

All three must be accessible there must be enough space and they must accept complex folder names with special characters.

A clean restart or new installation might be an idea along with making sure your SSD is structurally ok.

Hi @mlauber71,

I will look into it.

The plug-in which seems to produce the errors is the eclipse plug in.

Does this piece of information help you?
