Question

I have some strange error in Scout Eclipse. My college push some cone in git and I pull it out. On his computer everything works well, but on mine it's get error when launching SWT.

Error is :

I really try to make it works but I am running out of ideas.

== Ensure you are using the same target Platform as your colleague

Open Preferences > Plug-in development > Target Platform. You should have the same active target platform definition.

If you use running platform as active target definition, you should have exaclty the same Eclipse IDE installation to be able to compare.

== Ensure you start the application the same way

Open the client product file for example:

/<your-app>.ui.swt/products/development/<app>-swt-client-dev.product

Click on the Synchronize link in the testing section in the overview tab. (sometime you need to do this operation twice).

Start the application with the run or debug button in the same section.

== Test an other scout application on your computer

To determine if your eclipse scout IDE installation is OK or not, what happend when you create a test application in an other workspace? Do you manage to start it?

== Verify the content of your target platform

@marko-zadravec suggested to verify if you do not have 2 version of org.eclipse.jface in your target platform.

In the "Target Platform" preference page, select your active target definition in the list and click on the Edit button.

Switch to the Content tab. Check if you havent two org.eclipse.jface bundles.

== Reinstall the IDE

Sometimes reinstalling Eclipse for Scout Developers is the quickest solution to solve those kind of problems (Go to the Eclipse Downloads page).
