Vaadin 10+ Project Unable to fetch information about available starters

Hi,

currently we are developing with Vaadin8 and Eclipse. We wanted to evaluate Vaadin10+ (V14) and see if we need an upgrade.
But we are facing some start issues. I can download a starter project from vaadin, but i wanted to create a project in eclipse.
After i installed the 2019-12 Version of eclipse and made a new workspace i wanted to download the Vaadin Plugin. So far so good.
After that i wanted to create a Vaadin 10+ project and as you can see in the screenshot im facing such an problem without any solution.

Any ideas how we can resolve that?

Hello Tugrul, are you using proxy? If yes - I’d recommend you to configure it in Eclipse https://mkyong.com/web-development/how-to-configure-proxy-settings-in-eclipse/.

It still seems a connection issue, but i have no clue what exactly the problem is.

Thanks for the comments. It seems that library we’re using ignores the proxy settings. We already have an issue for it https://github.com/vaadin/eclipse-plugin/issues/798.

ah thanks i see, is there any workaround yet?

thank you very much.

A workaround until that is to use Maven archetype(com.vaadin:vaadin-archetype-application) or the web based project creator (vaadin.com/start).

cheers,
