vaadin-quick-start does not work

General
1

C:\programs\my-app> .\mvnw
Exception in thread “main” javax.net.ssl.SSLException: Received fatal alert: protocol_version

I have googled that error but did not get any solution for that.

Sounds like something to do with your system configuration. Which Java version are you using? Are you behind a proxy?

3

Java 8. No proxy.

Oh, since you’re probably using Windows, you should maybe run mvnw.cmd instead of the mvnw shell script. You might need to run it as an administrator on the first run.

Just my configurations or something with JDK were wrong.

I installed new JDK 12 and set JAVA_HOME to it and then it started to work.

Great!
