Description

Following the steps of https://jetty.org/docs/jetty/12/programming-guide/maven-jetty/jetty-maven-helloworld.html#configuring-embedded-jetty-with-maven gives error:

[ERROR] Failed to execute goal on project hello-world: Could not resolve dependencies for project org.example:hello-world:jar:0.1-SNAPSHOT: The following artifacts could not be resolved: org.eclipse.jetty:jetty-server:jar:12.0.10-SNAPSHOT (absent): Could not find artifact org.eclipse.jetty:jetty-server:jar:12.0.10-SNAPSHOT 

I looked up the latest version of this artifact at https://mvnrepository.com/artifact/org.eclipse.jetty/jetty-server/12.0.10, so I tried using 12.0.10 instead of 12.0.10-SNAPSHOT, and got a new error:

We need to get rid of the "-SNAPSHOT" portion of that example.

Use <jettyVersion>12.0.10</jettyVersion> for now.

We need to get rid of the "-SNAPSHOT" portion of that example.

Use <jettyVersion>12.0.10</jettyVersion> for now.

When I use that version and run the example as-is, I get the following error:

@LovingSalamander oops, looks like that documentation has not been ported to jetty-12. A better guide is to look at the javadoc, particularly for eg the Request.Handler which has a simple HelloWorld example: https://javadoc.jetty.org/jetty-12/org/eclipse/jetty/server/Request.Handler.html
