Hi,
The conflict may be occur when you have used studio for a while. To avoid this conflict, my suggestion is that use JDK 1.6 instead of 1.7. Please see the related reference https://community.talend.com/t5/Installing-and-Upgrading/Cannot-start-Talend-open-studio/td-p/94562
Is there any error log which is located in <Talend Studio installation path>/workspace/.metadata/.log for Talend Open Studio Data Integration.
In addition, try this solution:
Please follows the steps as below to restore the items.
1. Backup the workspace.
2. Delete the workspace and restart the studio.
3. Import all items from the backup of workspace done in step1.
Best regards
Sabrina

Hi,
There is unknown conflict problem when you use JDK 1.7. It suggested that you should use JDK 1.6.
In addition, please pay more attention on these points:
1. set the java environment correctly.
2. Make sure there is no space and Illegal character in your installation path.
Your feedback will be appreciated.
Best regards

Hi,
Which solution do you used to resolve it? Could you share your experience with us? Downgrade JDK 1.7 into JDK1.6 or delete the workspace?
Best regards

I face the same issue. If your workspace is put inside source control, there is chances to fix it.

Clone your workspace via source control to another folder (let say "Talend2", open talent . set up workspace to the new location of "Talend2", load project. If success then you have 50% chances now..

 

Now close "Talend2" workspace, open git.. go to the troublesome workspace (let call it "Talend1")

revert any local changes, make sure it fresh and on commit revision that working before.

 

Now try your luck, open "Talend1" using talend, delete project . Tick delete physical. Close talend.

Open source code control again, if any local changes (file deleted), just revert/restore it.

 

Now, open again Talend1" using talend. setup workspace, setup back the project. It will ask for restart. Just restart and your can open the project again.
