[resolved] cannot start Talend

[izumisawaa]

Hi
I cannot boot talend's start-up screen.

I confirmed talend's log file.
- ${LAST_TIME_TALEND_WORKSPACE}/.metadata/.log
The final root cause: rg.eclipse.core.internal.dtree.ObjectNotFoundException
-'/${LAST_TIME_TALEND_WORKSPACE}/metadata/connections/${CONNECTION_NAME}_${VERSION}.properties' was not found.
But, That properties File is found!!

I cannot use Studio at all.
Please teach what I should do.
Regards

Hi

TIS doesn't find the property file of the connection that fails in retrieve schema.

Are you creating a local connection? right?
Go the TIS studion installation folder/configuration and see if the file connection_user.properties exists, if so, delete the file connection_user.properties, restart TIS studio, create a local connection again, select the workspace which contians the project.

Hi,
Yes, I have only local workspace.
The result was the same though it deleted files(connection_user.properties and items) like your instruction.

Hi
OK, now I show you a way of restoring all the items:
1. Create a new project and login the project.
2. Go to workspace/old_project_folder/metadata/ and copy all the folders.(pic1)
3. Open the Navigator viewer of new project, open the new_project_name folder/metadata, right click on the metadata folder and paste them.(pic2)
4. Use the same way to restore all the items of code, context, joblet.
5. Finally, restore the job items, go to workspace/old_project_folder/process/, copy all the folders and items or some of items which you want to restore.
Open the Navigator viewer of new project, open the new_project_name folder/process, right click on the process folder and paste them.
6. Go back to Repository viewer and refresh.
Best regards

Hi,

My Workspace revived by having taught to you.

3. Open the Navigator viewer of new project, open the new_project_name folder/metadata, right click on the metadata folder and paste them.(pic2)

=>I re-made connection because I had made an error of the copy of metadata.
Additionally, there is no problem.
Thank you very match!
