[SOLVED] Cannot start a Tomcat server with the Community Server Connectors extension in VS Code

Cannot start a Tomcat server with the Community Server Connectors extension in VS Code

In VS Code I have created a Maven project for a Java Servlet (no Spring) and now I try to deploy the generated .war file to a local Tomcat 8.5 via the Community Server Connectors extension.

However when the extension loads I always get an error balloon with the message:

Unable to start the RSP server: Extension backend error - rsp error - community server connector failed to start - typeerror: cannot read properties of undefined (reading 'map')

And then when I try to click the Create New Server icon I get as a subsequent message:

Unable to create the server: Extension backend error - there are no rsp providers to choose from.

Any idea why this happens and how I can fix this? Or how can I debug this in more detail?

Solution

The issue seem to have been that I had used Java 8 as the JDK.

I now switched to a Java 17 JDK for VS Code - and it works: I can create a new Tomcat server under the "Servers - Community Server Connector" heading and start it successfully up.
