Error while adding New Resource in Thingworx Extension

Hi All,

I am trying to add a new Resource when creating a Extension in Eclipse.

But I am getting an error as " Please choose a valid Superclass - Class is not instance of: com.thingworx.resources.Resource". Attached the screenshot with the post.

Any idea, why this error is thrown.

NOTE: I have included the SDK zip while creating the project itself.

In addition to above, I also tried after adding few external JAR files to the project library.

Has anyone faced this error.

Thanks in Advance.

Yes. I too think it might be due to some compatibility issue.

When I used lower version SDK, I did not see this error.

With / without the external libraries, it was working okay.

Seems like either eclipse is not able to recognize the superclass or it is not available. Can you click on the browse button beside superclass and do you see this class coming from thingworx-ext-sdk-version.jar, something like this.
